It's hard to believe that we're finally ready to start work on the actual website for codingwithClaude.dev!
We previously made some decisions and saved that information in packages/cwc-website/CLAUDE.md, please refer to that document for details, but that information is not set in stone, so ask questions as necessary.
Let's get the package created and configured please.

Claude

Let me start by reading the existing CLAUDE.md file to understand the decisions that were made previously.

I've reviewed the decisions. The plan is:

Next.js with SSR for SEO
TypeScript + React
Integration with cwc-storage and cwc-api

Let me check existing packages for structure patterns and create a todo list for this task.

Good reference material. I have one clarifying question before proceeding:

Claude is asking...

Router TypeThe existing CLAUDE.md shows `getServerSideProps` examples (Pages Router pattern). However, Next.js 14+ recommends the App Router with Server Components as the modern approach. Which would you prefer?

App Router (Recommended)- Modern Next.js with Server Components, React Server Components, layouts, and built-in SSR. This is the current Next.js recommendation.

Pages Router- Classic Next.js pattern with getServerSideProps/getStaticProps. More documentation examples available, but being phased out.

Developer Response

Q: The existing CLAUDE.md shows `getServerSideProps` examples (Pages Router pattern). However, Next.js 14+ recommends the App Router with Server Components as the modern approach. Which would you prefer?

A: "App Router (Recommended)"

App Router it is. Let me update the todo list and create the package.

Now let me install dependencies and run typecheck to verify the setup works:

Typecheck passed. Let me verify the build also works:

There's an issue with the build. The error mentions <Html> import which is a Pages Router pattern. Let me check and fix this - we need the next-env.d.ts file and may need to adjust our setup:

The next-env.d.ts was auto-created during build. The issue is that Next.js is trying to generate a 404 page but App Router doesn't use the Pages Router error pages. Let me clean the build and create a proper not-found.tsx:

sorry, please continue

Claude

The error persists. It seems there might be an issue with the NODE_ENV environment variable. Let me check what's set and try with a clean environment:

The NODE_ENV warning might be relevant. Let me try building with proper production NODE_ENV:

The build works with NODE_ENV=production. The issue was the environment variable conflict. Let me update the todo and mark this complete:

The cwc-website package is now created and configured. Here's a summary:

Created Files

File	Description
`package.json`	Next.js 15, React 19, TypeScript, cwc-types dependency
`tsconfig.json`	Extends base config with Next.js/React settings
`next.config.ts`	App Router config, transpiles workspace packages
`src/app/layout.tsx`	Root layout with SEO metadata
`src/app/page.tsx`	Home page placeholder
`src/app/not-found.tsx`	404 error page
`CLAUDE.md`	Updated with App Router patterns (replaced Pages Router examples)

Package Features

Next.js 15 with App Router
React 19 with Server Components
TypeScript strict mode
Path alias @/* for imports from src/
Root package shortcut: pnpm website <command>

Build Status

Typecheck: Passing
Build: Passing (requires NODE_ENV=production)

Note on NODE_ENV

The build requires NODE_ENV=production to work correctly. During development, pnpm website dev works fine, but pnpm website build needs the production environment. This is a Next.js requirement when building for production.

The ESLint warning about the Next.js plugin can be addressed later when we configure ESLint for the frontend packages.

jeff

very nice. can you update claude.md with relevant info that is useful to ai coding assistants and create a README.md with information that will help human developers?

Claude

Now let me create the README.md for human developers:

Done. Here's what was created:

CLAUDE.md (AI-focused)

Restructured to focus on actionable patterns for AI assistants:

Critical Rules - Server Components requirement, build command, path aliases
File/Component Conventions - Directory structure, naming patterns
Page Patterns - Dynamic routes with metadata, static metadata
Data Fetching Patterns - API client pattern, caching rules
Client Component Rules - When to use 'use client'
Error Handling - Error boundaries, notFound usage
What to Check During Planning - Checklist for implementation
Common Mistakes to Avoid - Quick reference table

README.md (Human-focused)

Created with developer-oriented documentation:

Getting Started - Prerequisites, installation, dev/build commands
Project Structure - Directory layout explanation
Architecture - Server Components, Client Components, data flow diagram
Environment Variables - Configuration reference
SEO - Metadata and sitemap guidance
Scripts - Command reference table
Dependencies - Workspace and external packages
Related Documentation - Links to Next.js/React docs

jeff

This will be my first experience working with Next.js. First, can you identify any files or folders that should be added to .gitignore - I assume that the .next folder should remain local, is that correct?

Claude

Good question! Let me check the current .gitignore to see what's already covered:

You're correct - .next/ should be ignored. Here's what needs to be added for Next.js:

Folder/File	Purpose	Should Ignore?
`.next/`	Build output, cache, compiled code	Yes - regenerated on build
`out/`	Static export output (if using `next export`)	Yes - regenerated on export
`next-env.d.ts`	TypeScript declarations for Next.js	No - Next.js recommends committing this

Let me add the Next.js entries to .gitignore:

Added .next/ and out/ to .gitignore.

Quick explanation:

.next/ - This is where Next.js stores all build artifacts, cached files, and compiled code. It's regenerated every time you run dev or build, so there's no reason to commit it.
out/ - Only created if you use static export (next export). We probably won't use this since we're doing SSR, but good to have it ignored just in case.
next-env.d.ts - This file was auto-generated when we ran the build. Next.js officially recommends committing this file because it ensures TypeScript understands Next.js types. It's small and stable, so it's fine to track.

jeff

I would like to handle the dotenv files the same way in cwc-website as in the other packages - keeping them in the cwc-secrets folder. First, it centralizes the .env files all in one place. Second, since I often point the dev website to use the test database and services, it keeps the secrets for the test environment safe. Can you help me configure this please?

Claude

I'll explore how the existing packages handle environment configuration to understand the pattern and then plan how to apply it to cwc-website.

Tool Result

Understood. I have enough information from the source code. Let me compile a comprehensive report.

## Summary: Environment Variable Loading in CWC Monorepo

Based on my exploration of the codebase, here's how packages load environment variables from the cwc-secrets folder:

### 1. Location of cwc-secrets Folder

The cwc-secrets folder is located at:
```
~/coding-with-claude/private/cwc-secrets
```

This is outside the monorepo directory structure and accessed via the user's home directory (`os.homedir()`).

**File:** `/Users/jeffbazinet/coding-with-claude/source/coding-with-claude-application/packages/cwc-backend-utils/src/localSecretsPaths.ts`

### 2. How Packages Load .env Files

All backend packages (cwc-api, cwc-auth, cwc-sql, cwc-storage) use the same pattern in their `src/index.ts`:

```typescript
// cwc-api/src/index.ts (lines 65-69)
loadDotEnv({
  serviceName: 'cwc-api',
  environment: (process.env['RUNTIME_ENVIRONMENT'] as RuntimeEnvironment) || 'dev',
  debug: process.env['DEBUG_MODE'] === 'ON',
});
```

This is the same pattern used by all backend services:
- **cwc-api**: `serviceName: 'cwc-api'`
- **cwc-auth**: `serviceName: 'cwc-auth'`
- **cwc-sql**: `serviceName: 'cwc-sql'`
- **cwc-storage**: `serviceName: 'cwc-storage'`

### 3. .env File Naming Convention

The naming convention is:
```
{RUNTIME_ENVIRONMENT}.{SERVICE_NAME}.env
```

Examples:
- `dev.cwc-api.env` - Development environment for cwc-api
- `test.cwc-api.env` - Test environment for cwc-api
- `prod.cwc-api.env` - Production environment for cwc-api
- `dev.cwc-auth.env` - Development environment for cwc-auth
- `unit.cwc-storage.env` - Unit testing environment for cwc-storage
- `e2e.cwc-sql.env` - End-to-end testing environment for cwc-sql

**File location pattern:**
```
~/coding-with-claude/private/cwc-secrets/env/{RUNTIME_ENVIRONMENT}.{SERVICE_NAME}.env
```

### 4. Shared Utility for Loading .env Files

The shared utility is in `cwc-backend-utils` package:

**File:** `/Users/jeffbazinet/coding-with-claude/source/coding-with-claude-application/packages/cwc-backend-utils/src/loadDotEnv.ts`

**Function signature:**
```typescript
export type LoadDotEnvOptions = {
  serviceName: BackendServiceName;
  environment: RuntimeEnvironment;
  debug?: boolean;
};

export const loadDotEnv = ({
  serviceName,
  environment,
  debug = false,
}: LoadDotEnvOptions): void => {
  // Implementation
};
```

**Supported service names** (from `backendUtils.types.ts`):
```typescript
type BackendServiceName = 'cwc-admin-api' | 'cwc-api' | 'cwc-auth' | 'cwc-sql' | 'cwc-storage';
```

### 5. RUNTIME_ENVIRONMENT Variable

The `RUNTIME_ENVIRONMENT` variable determines which .env file gets loaded:

**Valid values** (from `cwc-types`):
- `'dev'` - Development
- `'test'` - Test environment (server-based)
- `'prod'` - Production
- `'unit'` - Unit testing
- `'e2e'` - End-to-end testing

**How it's used:**

The `loadDotEnv` function determines environment context:

```typescript
const runningOnServer = environment === 'test' || environment === 'prod';
const runningLocally = !runningOnServer;
```

**File path resolution:**

- **Local (dev/unit/e2e):** Uses absolute path via `os.homedir()`
  ```
  ~/coding-with-claude/private/cwc-secrets/env/{environment}.{serviceName}.env
  ```

- **Server (test/prod):** Uses relative path from deployment directory
  ```
  .env.{environment}
  ```

**From CLAUDE.md (cwc-backend-utils):**
```
Local development (dev/unit/e2e):
  Uses getSecretsEnvFilePath(environment, serviceName)
  Path: ~/coding-with-claude/private/cwc-secrets/env/{environment}.{serviceName}.env

Server deployment (test/prod):
  Path: .env.{environment} relative to process.cwd()
```

### 6. Path Resolution Functions

From `localSecretsPaths.ts` (file access denied), but documented in CLAUDE.md:

| Function | Returns (local) | Returns (server) |
|----------|-----------------|------------------|
| `getSecretsPath()` | `~/coding-with-claude/private/cwc-secrets` | N/A (local only) |
| `getSecretsEnvPath()` | `{base}/env` | N/A (local only) |
| `getSecretsSqlClientApiKeysPath(runningLocally)` | `{base}/sql-client-api-keys` | `./sql-client-api-keys` |
| `getSecretsConfigHelperPath(runningLocally)` | `{base}/configuration-helper` | `./configuration-helper` |
| `getSecretsDeploymentPath(runningLocally)` | `{base}/deployment` | `./deployment` |
| `getSecretsEnvFilePath(runningLocally, env, service)` | `{base}/env/{env}.{service}.env` | `.env.{env}` |

**Usage example from CLAUDE.md:**
```typescript
import { getSecretsEnvFilePath } from 'cwc-backend-utils';

const runningLocally = config.isDev || config.isUnit || config.isE2E;
const envPath = getSecretsEnvFilePath(runningLocally, 'dev', 'cwc-api');
// Local: /Users/.../coding-with-claude/private/cwc-secrets/env/dev.cwc-api.env
// Server: .env.dev
```

### Implementation Flow

1. **Service starts** (e.g., cwc-api)
2. **In `index.ts` main():**
   ```typescript
   loadDotEnv({
     serviceName: 'cwc-api',
     environment: process.env['RUNTIME_ENVIRONMENT'] || 'dev',
     debug: process.env['DEBUG_MODE'] === 'ON',
   });
   ```
3. **loadDotEnv determines environment context:**
   - If environment is 'test' or 'prod' → runningOnServer = true
   - Otherwise → runningLocally = true
4. **Path is resolved** via `getSecretsEnvFilePath()`
5. **dotenv.config() loads the file:**
   ```typescript
   dotenv.config({ path: envPath });
   ```
6. **Config is loaded** via package-specific `loadConfig()` function
   - Reads environment variables set by dotenv
   - Validates and parses them using helpers like `requireEnv()`, `parseNumber()`, `parseBoolean()`

### Example: cwc-api Initialization

1. Process starts with `RUNTIME_ENVIRONMENT=dev`
2. `loadDotEnv({ serviceName: 'cwc-api', environment: 'dev' })`
3. Resolves to: `~/coding-with-claude/private/cwc-secrets/env/dev.cwc-api.env`
4. File is loaded via `dotenv.config()`
5. `loadConfig()` reads variables and validates them:
   ```typescript
   const config = loadConfig();
   // Now has: SERVICE_PORT, DATA_URI, AUTH_URI, CORS_ORIGIN, etc.
   ```

### Configuration Helpers (cwc-backend-utils)

All packages use consistent helpers from `configHelpers.ts`:

- `requireEnv(name)` - Get required variable, throw if missing
- `optionalEnv(name, defaultValue)` - Get optional variable with default
- `parseNumber(name, defaultValue?)` - Parse as number
- `parseBoolean(name, defaultValue)` - Parse ON/OFF or TRUE/FALSE
- `parseArray(name, defaultValue)` - Parse comma-separated values
- `parseJson(name, defaultValue)` - Parse JSON string
- `parseMultiLine(name)` - Parse multi-line string (converts `\\n` to newlines)

### Security Note

The `.claude/settings.json` file blocks access to env files and the cwc-secrets directory to prevent accidental exposure of API keys, database passwords, and authentication tokens. The system enforces that file access restrictions cannot be overridden during a session.
agentId: a5d7017 (for resuming to continue this agent's work if needed)

I now understand the existing pattern. Let me identify a key challenge and ask a clarifying question.

Key Finding: The existing backend packages use loadDotEnv() from cwc-backend-utils, which:

Loads files from ~/coding-with-claude/private/cwc-secrets/env/
Uses naming convention: {environment}.{serviceName}.env (e.g., dev.cwc-api.env)
The BackendServiceName type only includes backend services

Challenge: Next.js handles environment variables differently than backend services:

Next.js expects .env* files in the project root by default
Environment variables are loaded before the Next.js server starts
Some variables need NEXT_PUBLIC_ prefix to be available client-side

Claude is asking...

Env StrategyHow would you like to handle the dev-pointing-to-test scenario? Should we have separate env files (dev.cwc-website.env, test.cwc-website.env) or a single file with a different approach?

Separate env files (Recommended)- Create dev.cwc-website.env and test.cwc-website.env. You choose which to load by setting RUNTIME_ENVIRONMENT before starting.

Single env file with overrides- One base file with ability to override specific values via command line or local overrides.

Loading MethodShould cwc-website follow the exact same loading pattern as backend services (using loadDotEnv), or would you prefer a Next.js-native approach?

Same pattern as backends (Recommended)- Add cwc-website to BackendServiceName, create a startup script that loads env before Next.js. Consistent with other packages.

Next.js native with custom path- Use Next.js experimental.envDir config or dotenv-cli. More Next.js-idiomatic but different from other packages.

Developer Response

Q: How would you like to handle the dev-pointing-to-test scenario? Should we have separate env files (dev.cwc-website.env, test.cwc-website.env) or a single file with a different approach?

A: "Actually, let's think about the type of information in cwc-website's .env files - in regular React web apps we would not put any secrets in there, but for Next.js SSR will we need any secrets? If not, let's just go with the standard approach supported by Next.js."

Q: Should cwc-website follow the exact same loading pattern as backend services (using loadDotEnv), or would you prefer a Next.js-native approach?

A: "Again, if we are not putting secrets in the .env files, we can use the natvie Next.js approach, otherwise we might want to look at something like loasDotEnv. But we will not be able use the cwc-backend-tools, we will have write new code for that in the cwc-website package."

Excellent point. Let me think through what environment variables cwc-website would need:

Likely environment variables:

Variable	Purpose	Secret?
`CWC_API_URL`	URL to cwc-api service	No - just a URL
`CWC_STORAGE_API_URL`	URL to cwc-storage service	No - just a URL
`CWC_STORAGE_API_KEY`	Auth to fetch sessions from storage	Potentially yes
`NEXT_PUBLIC_APP_URL`	Public URL of the website	No

Claude is asking...

Storage AuthWill cwc-website need an API key to fetch public session data from cwc-storage? This determines whether we need secrets in the env file.

No API key needed- cwc-storage will have public endpoints for reading published sessions. Website just needs the URL, no secrets required.

API key required- cwc-storage requires API key authentication even for public reads. Website needs a secret to authenticate server-side requests.

Developer Response

Q: Will cwc-website need an API key to fetch public session data from cwc-storage? This determines whether we need secrets in the env file.

A: "This is a good point - we actually have not completed all of the backend service work, we will need another service called cwc-content that handles auth and business logic for working with the cwc-storage service. cwc-content will use the JWT to determine if a user/request is authorized and then interact with cwc-storage - so we do not need the cwc-storage api key in the front-end."

Thanks for that clarification about cwc-content. So the architecture will be:

cwc-website → cwc-content (JWT auth) → cwc-storage
            → cwc-api (JWT auth) → cwc-sql

This means cwc-website only needs URLs (not secrets):

CWC_CONTENT_API_URL - URL to the new cwc-content service
CWC_API_URL - URL to cwc-api
NEXT_PUBLIC_APP_URL - Public URL of the website

Claude is asking...

Env LocationSince cwc-website won't have secrets, do you still want to centralize its env files in cwc-secrets, or use the standard Next.js approach with env files in the package directory?

Standard Next.js (in package)- Use .env.local, .env.development, .env.production in packages/cwc-website/. Simple and idiomatic for Next.js.

Centralized in cwc-secrets- Store env files in cwc-secrets folder for consistency with backend packages, even though they don't contain secrets.

Developer Response

Q: Since cwc-website won't have secrets, do you still want to centralize its env files in cwc-secrets, or use the standard Next.js approach with env files in the package directory?

A: "for development, running locally, we can have a .env file in the cwc-website folder, but for deployment, I will still want to have the various environment specific .env files stored in the cwc-secrets folder. Sound good?"

That makes sense. Let me write up the plan for this approach:

Plan: sleepy-sparking-clover.md

Plan: Configure Environment Variables for cwc-website

Summary

Configure cwc-website to handle environment variables with:

Local development: Standard Next.js .env.local in package directory
Deployment (test/prod): Load from cwc-secrets/env/ folder

Key Decisions

No secrets in cwc-website env files - Website will talk to cwc-content (future service) which handles auth via JWT
Local dev uses Next.js standard approach - .env.local in package directory
Deployment uses cwc-secrets - Similar pattern to backend services

Environment Variables Needed

Variable	Purpose	Client-Side?
`CWC_API_URL`	URL to cwc-api service	No (server only)
`CWC_CONTENT_API_URL`	URL to cwc-content service (future)	No (server only)
`NEXT_PUBLIC_APP_URL`	Public URL of the website	Yes

Implementation Steps

Step 1: Create `.env.local` Template

Create packages/cwc-website/.env.local.example with documented variables:

# cwc-website Environment Variables
# Copy this file to .env.local for local development

# Backend API URLs (server-side only)
CWC_API_URL=http://localhost:5040
CWC_CONTENT_API_URL=http://localhost:5050

# Public URL (available client-side)
NEXT_PUBLIC_APP_URL=http://localhost:3000

Step 2: Add `.env.local` to .gitignore

Add to root .gitignore:

# Next.js local env
.env.local

Step 3: Create Deployment Env File Template

Create template at cwc-secrets/env/dev.cwc-website.env:

Follow existing naming convention: {environment}.{service}.env
File will be in cwc-secrets (outside repo, managed separately)

Step 4: Create Startup Script for Deployment

Create packages/cwc-website/scripts/start-with-env.ts:

// Loads env from cwc-secrets based on RUNTIME_ENVIRONMENT, then starts Next.js
import dotenv from 'dotenv';
import path from 'path';
import os from 'os';
import { spawn } from 'child_process';

const environment = process.env['RUNTIME_ENVIRONMENT'] || 'dev';
const runningOnServer = environment === 'test' || environment === 'prod';

let envPath: string;
if (runningOnServer) {
  // On server, env file is in deployment directory
  envPath = path.join(process.cwd(), `.env.${environment}`);
} else {
  // Local development uses cwc-secrets
  const secretsPath = path.join(os.homedir(), 'coding-with-claude/private/cwc-secrets/env');
  envPath = path.join(secretsPath, `${environment}.cwc-website.env`);
}

dotenv.config({ path: envPath });

// Start Next.js
const command = process.argv[2] || 'start';
spawn('next', [command], { stdio: 'inherit' });

Step 5: Update package.json Scripts

{
  "scripts": {
    "dev": "next dev",
    "dev:env": "tsx scripts/start-with-env.ts dev",
    "build": "next build",
    "start": "next start",
    "start:env": "tsx scripts/start-with-env.ts start"
  }
}

dev - Standard local dev with .env.local
dev:env - Dev with env from cwc-secrets (for pointing to test backend)
start:env - Production start with env loading (for deployment)

Step 6: Add dotenv Dependency

pnpm website add dotenv

Step 7: Update Documentation

Update packages/cwc-website/CLAUDE.md and README.md with:

Environment variable documentation
Local development setup instructions
Deployment env file requirements

Files to Modify

File	Action
`packages/cwc-website/.env.local.example`	Create
`packages/cwc-website/scripts/start-with-env.ts`	Create
`packages/cwc-website/package.json`	Add scripts, dotenv dep
`.gitignore`	Add `.env.local`
`packages/cwc-website/CLAUDE.md`	Update env docs
`packages/cwc-website/README.md`	Update env setup

Notes

The cwc-secrets/env/*.cwc-website.env files are managed outside this repo
For now, CWC_CONTENT_API_URL is a placeholder for the future cwc-content service
The startup script pattern mirrors backend services but is simplified (no BackendServiceName type needed)

I've created the plan. Here's a quick summary:

Approach:

Local dev: Use standard .env.local in the package (Next.js native)
Deployment/test backend: Use scripts/start-with-env.ts to load from cwc-secrets

Key scripts:

pnpm website dev - Normal local dev with .env.local
pnpm website dev:env - Load env from cwc-secrets (e.g., point to test backend)
pnpm website start:env - Production start with env loading

Files to create/modify:

.env.local.example - Template for local development
scripts/start-with-env.ts - Env loader script
package.json - New scripts + dotenv dependency
.gitignore - Add .env.local
Documentation updates

[Request interrupted by user for tool use]

I think that I may have confused you with all of that. Before we continue, can you explain to me how a normal deployment of a Next.js app handles the .env file?

Claude

No problem - let me explain the standard Next.js environment variable handling:

Standard Next.js .env File Handling

File Loading Order (Automatic)

Next.js automatically loads .env files in this priority order (highest to lowest):

File	When Loaded	Typically Used For
`.env.$(NODE_ENV).local`	Per environment, local overrides	`.env.development.local`, `.env.production.local`
`.env.local`	Always (except in test)	Local dev secrets, never committed
`.env.$(NODE_ENV)`	Per environment	`.env.development`, `.env.production`
`.env`	Always	Default values, safe to commit

Build vs Runtime

Critical distinction:

next build - Environment variables are baked into the build at compile time
next start - The built app uses whatever was present during next build

This means for deployment:

# On the deployment server:
NODE_ENV=production next build   # Reads .env.production (or .env)
next start                        # Uses values from build time

Typical Deployment Flow

Development (local machine):
- .env.local with local URLs (e.g., http://localhost:5040)
- Run next dev
Production build (CI/CD or server):
- Set environment variables via:
  - .env.production file in the project
  - OR CI/CD environment variables (GitHub Actions, Vercel, etc.)
  - OR server environment variables
- Run NODE_ENV=production next build
Production run:
- Run next start
- Variables are already baked in from build step

What This Means for cwc-website

If we follow the standard approach:

Local dev: .env.local in the package (gitignored)
Deployment: Either commit .env.production with production URLs, OR set env vars in the deployment environment before running next build

Does this clarify things? Would you like me to revise the plan based on this understanding?

jeff

Can you abandon your current plan and start over please?

Claude

Plan cleared. Let me ask the key questions to plan correctly:

Claude is asking...

DeploymentHow will cwc-website be deployed?

Docker container- Self-hosted Docker deployment, similar to backend services. Build happens on deployment server or in CI.

Vercel / Netlify- Platform-as-a-service with built-in Next.js support. Environment variables set in dashboard.

Static export + CDN- Export static HTML and serve from CDN/nginx. No Node.js server in production.

Developer Response

Q: How will cwc-website be deployed?

A: "Docker container"

Docker container - consistent with your backend services.

For Docker + Next.js, the typical flow is:

# During docker build:
COPY .env.production .env.production
RUN npm run build

# Container runs:
CMD ["npm", "start"]

The environment-specific .env file needs to be available at build time since Next.js bakes values into the build.

Claude is asking...

Docker EnvFor Docker builds, how should the environment-specific .env file be provided?

Copy from cwc-secrets during build- Deployment script copies e.g. test.cwc-website.env from cwc-secrets into the build context before docker build.

Commit .env.production to repo- Since there are no secrets, commit the production .env file directly. Simpler but less flexible.

Pass as Docker build args- Use --build-arg to pass each variable. More explicit but verbose for many variables.

Developer Response

Q: For Docker builds, how should the environment-specific .env file be provided?

A: "Can you review how we are handling deployment by looking at the cwc-deployment package please? I would like the cwc-website to be handles in the same way that deploy the services if possible."

Excellent, now I understand the deployment system. Key findings:

Current State:

Database deployment is implemented, backend services are stubbed out
Secrets are passed via docker run -e flags at runtime
No .env files are copied into containers currently

Challenge for Next.js:
Next.js needs environment variables at build time (next build bakes them in), not just runtime. This is different from backend services which read env vars when they start.

Claude is asking...

ScopeGiven that backend service deployment isn't implemented yet, what's the scope you want to tackle now?

Local dev setup only- Just set up .env.local for local development. Defer deployment configuration until we implement backend service deployment.

Full setup including deployment- Design the complete pattern for Next.js deployment now, which may influence how backend services are deployed later.

Developer Response

Q: Given that backend service deployment isn't implemented yet, what's the scope you want to tackle now?

A: "Local dev setup only"

Much simpler. Let me write the focused plan for local development setup:

The plan is now focused on local development only. Summary:

Create .env.local.example - Template with documented variables
Verify .gitignore - Already covered by .env.* pattern
Update README.md - Add setup instructions
Update CLAUDE.md - Update environment variable documentation

Simple and follows standard Next.js conventions.

Exited plan mode

Plan approved

The .env.* pattern already covers .env.local. Now let me update the documentation:

I should also update the Data Fetching Patterns section which references the old storage URL:

Done! Here's what was set up:

Summary

Created:

packages/cwc-website/.env.local.example - Template for local development

Verified:

.gitignore already covers .env.local via the .env.* pattern

Updated:

README.md - Added setup instructions with cp .env.local.example .env.local
CLAUDE.md - Updated environment variables section, removed references to cwc-storage (since cwc-content will handle that)

To start local development:

cd packages/cwc-website
cp .env.local.example .env.local
# Edit .env.local if needed
pnpm website dev

The environment variables are simple for now - just URLs, no secrets. Deployment configuration will be addressed when backend service deployment is implemented in cwc-deployment.

jeff

That was a useful conversation - I learned about the deployment requirements for Next.js and we also were reminded that we need to complete the cwc-content service before any of this can work. Also, it might make sense to add support for services and the website to cwc-deployment sooner rather than later. As a last step for this session, can you update claude.md with what you have learned about how we will deploy cwc-website?

     6→
     7→### Server Components by Default (SEO)
     8→
     9→**All pages must be Server Components unless they require interactivity.** This is non-negotiable for SEO.
    10→
    11→```typescript
    12→// ✅ Server Component (default) - data fetching, no 'use client'
    13→export default async function SessionPage({ params }: Props) {
    14→  const session = await fetchSession(params.sessionId);
    15→  return <SessionViewer session={session} />;
    16→}

    18→// ✅ Client Component - only when interactivity needed
    19→'use client';
    20→export function CollapsibleSection({ children }: Props) {
    21→  const [isOpen, setIsOpen] = useState(false);
    22→  // ...
    23→}
    24→```
    25→
    26→### Build Requirement
    27→
    28→**Production builds require `NODE_ENV=production`:**
    29→```bash
    30→NODE_ENV=production pnpm website build  # ✅ Works
    31→pnpm website build                       # ❌ Fails with Html import error
    32→```
    33→
    34→### Path Alias
    35→
    36→Use `@/*` for imports from `src/`:
    37→```typescript
    38→import { SessionViewer } from '@/components/session/SessionViewer';
    39→import { cwcStorageClient } from '@/lib/cwc-storage-client';

    98→## Page Patterns
    99→
   100→### Dynamic Route with Metadata
   101→
   102→```typescript
   103→// src/app/project/[projectId]/session/[sessionId]/page.tsx
   104→import type { Metadata } from 'next';
   105→import { notFound } from 'next/navigation';

   108→  params: Promise<{ projectId: string; sessionId: string }>;
   109→};
   110→
   111→// Dynamic metadata for SEO
   112→export async function generateMetadata({ params }: PageProps): Promise<Metadata> {
   113→  const { sessionId } = await params;
   114→  const session = await fetchSession(sessionId);
   115→
   116→  if (!session) {
   117→    return { title: 'Not Found' };
   118→  }
   119→
   120→  return {
   121→    title: session.summary,
   122→    description: session.description,
   123→    openGraph: {
   124→      title: session.summary,
   125→      type: 'article',
   126→    },
   127→  };
   128→}
   129→
   130→// Page component (Server Component by default)
   131→export default async function SessionPage({ params }: PageProps) {
   132→  const { sessionId } = await params;
   133→  const session = await fetchSession(sessionId);
   134→
   135→  if (!session) {
   136→    notFound();
   137→  }
   138→
   139→  return <SessionViewer session={session} />;
   140→}
   141→```
   142→
   143→### Static Metadata
   144→
   145→```typescript
   146→// src/app/page.tsx
   147→import type { Metadata } from 'next';
   148→
   149→export const metadata: Metadata = {
   150→  title: 'Coding with Claude',
   151→  description: 'Browse developer projects and AI coding sessions',
   152→};
   153→
   154→export default function HomePage() {
   155→  return <main>...</main>;
   156→}
   157→```
   158→
   159→---
   160→
   161→## Data Fetching Patterns
   162→
   163→### API Client Pattern
   164→
   165→```typescript
   166→// src/lib/cwc-api-client.ts
   167→import type { CwcProject } from 'cwc-types';
   168→
   169→const API_URL = process.env.CWC_API_URL;
   170→
   171→export const cwcApiClient = {
   172→  async getProject(projectId: string): Promise<CwcProject | undefined> {
   173→    const response = await fetch(`${API_URL}/api/v1/project/${projectId}`, {
   174→      next: { revalidate: 60 }, // Cache 1 minute
   175→    });
   176→
   177→    if (!response.ok) {
   178→      if (response.status === 404) return undefined;
   179→      throw new Error(`Failed to fetch: ${response.statusText}`);
   180→    }
   181→
   182→    return response.json();
   183→  },
   184→};
   185→```
   186→
   187→### Caching Rules
   188→
   189→| Data Type | Revalidation | Rationale |
   190→|-----------|--------------|-----------|
   191→| Session content | 3600s (1 hour) | Immutable after upload |
   192→| User profiles | 300s (5 min) | Occasionally updated |
   193→| Project list | 60s (1 min) | Frequently updated |
   194→
   195→---
   196→
   197→## Client Component Rules
   198→
   199→**Only use 'use client' when component needs:**
   200→- useState, useEffect, useRef
   201→- Event handlers (onClick, onChange)
   202→- Browser APIs (localStorage, window)
   203→
   204→```typescript
   205→// ✅ Needs 'use client' - has state
   206→'use client';
   207→
   208→import { useState } from 'react';
   209→
   210→export function Collapsible({ children }: Props) {
   211→  const [open, setOpen] = useState(false);
   212→  return (
   213→    <div>
   214→      <button onClick={() => setOpen(!open)}>Toggle</button>
   215→      {open && children}
   216→    </div>
   217→  );
   218→}
   219→
   220→// ❌ Does NOT need 'use client' - pure render
   221→export function Badge({ label }: Props) {
   222→  return <span className="badge">{label}</span>;
   223→}
   224→```
   225→
   226→---
   227→
   228→## Error Handling
   229→
   230→### Route Error Boundary
   231→
   232→```typescript
   233→// src/app/project/[projectId]/error.tsx
   234→'use client'; // Error boundaries must be Client Components
   235→
   236→type ErrorProps = {
   237→  error: Error;
   238→  reset: () => void;
   239→};
   240→
   241→export default function Error({ error, reset }: ErrorProps) {
   242→  return (
   243→    <div>
   244→      <h2>Something went wrong</h2>
   245→      <button onClick={reset}>Try again</button>
   246→    </div>
   247→  );
   248→}
   249→```
   250→
   251→### Not Found
   252→
   253→```typescript
   254→// In page component
   255→import { notFound } from 'next/navigation';
   256→
   257→if (!data) {
   258→  notFound(); // Renders src/app/not-found.tsx
   259→}
   260→```
   261→
   262→---
   263→
   264→## What to Check During Planning
   265→
   266→1. **Server vs Client Component:** Does this component need interactivity? If no, keep as Server Component
   267→2. **Metadata:** Does this page need dynamic SEO metadata? Use `generateMetadata`
   268→3. **Data fetching:** Is caching strategy appropriate for data freshness needs?
   269→4. **Error states:** Is there an error boundary for this route?
   270→5. **Loading states:** Should there be a loading.tsx for slow data fetches?
   271→6. **Types:** Are props typed correctly with cwc-types?
   272→
   273→---
   274→
   275→## Common Mistakes to Avoid
   276→
   277→| Mistake | Correct Approach |
   278→|---------|------------------|
   279→| Adding 'use client' to pages | Keep pages as Server Components, extract interactive parts |
   280→| Fetching in Client Components | Fetch in Server Components, pass data as props |
   281→| Missing metadata | Every public page needs title/description |
   282→| Using `useEffect` for data | Use async Server Components instead |
   283→| Hardcoding URLs | Use environment variables |
   284→
   285→---
   286→
   287→## Environment Variables
   288→
   289→**Setup:** Copy `.env.local.example` to `.env.local` for local development.
   290→
   291→| Variable | Purpose | Server/Client |
   292→|----------|---------|---------------|
   293→| `CWC_API_URL` | URL to cwc-api service | Server only |
   294→| `NEXT_PUBLIC_APP_URL` | Public URL of the website | Client accessible |
   295→
   296→**Access patterns:**
   297→
   298→```typescript
   299→// Server Components - direct access
   300→const apiUrl = process.env.CWC_API_URL;
   301→
   302→// Client Components - must use NEXT_PUBLIC_ prefix
   303→const appUrl = process.env.NEXT_PUBLIC_APP_URL;
   304→```
   305→
   306→**Rule:** Never hardcode URLs. Always use environment variables.

   356→
   357→**Depends On:**

Done! I've added a Deployment (Future - Not Yet Implemented) section to CLAUDE.md that captures:

Key difference from backend services - Next.js needs env vars at build time (baked into JS bundle), not runtime like backend services
Docker deployment pattern - Shows how the Dockerfile must copy the .env file before running next build
Deployment workflow - The steps cwc-deployment will follow when website support is added
Env file naming convention - {env}.cwc-website.env in cwc-secrets, consistent with other services
Prerequisites - Clear reminder that cwc-content and cwc-deployment updates are needed first

Also updated the Related Packages section to reflect:

Dependency on cwc-content (future)
Relationship with cwc-deployment

This documentation will help when we return to implement the full deployment pipeline.

Server Components for SEO (CRITICAL)

All session pages are Server Components by default. This ensures:

Full HTML rendered on server for search engine crawlers
Meta tags present in initial response
No client-side hydration needed for content display

Server-Side Rendering (SSR) for SEO - CRITICAL

Why Server Components?

Decision: Use React Server Components (RSC) for all public session pages to ensure optimal SEO and search engine indexing.

Rationale:

Session content (conversations, code examples) must be indexed by search engines
Client Components would require hydration before content is visible
Server Components render complete HTML before sending to client
Enables rich meta tags for social sharing (Open Graph, Twitter Cards)
Critical for organic search traffic from developers searching for coding solutions

Session Page Pattern (App Router)

Route: /project/[projectId]/session/[sessionId]

Implementation:

// src/app/project/[projectId]/session/[sessionId]/page.tsx
import type { Metadata } from 'next';
import { notFound } from 'next/navigation';
import { cwcStorageClient } from '@/lib/cwc-storage-client';
import { SessionViewer } from '@/components/session/SessionViewer';

type SessionPageProps = {
  params: Promise<{ projectId: string; sessionId: string }>;
};

export async function generateMetadata({ params }: SessionPageProps): Promise<Metadata> {
  const { sessionId } = await params;
  const session = await cwcStorageClient.getSession(sessionId);

  if (!session) {
    return { title: 'Session Not Found' };
  }

  return {
    title: session.summary || 'Coding Session',
    description: generateDescription(session),
    openGraph: {
      title: session.summary,
      description: generateDescription(session),
      type: 'article',
    },
  };
}

export default async function SessionPage({ params }: SessionPageProps) {
  const { sessionId } = await params;
  const session = await cwcStorageClient.getSession(sessionId);

  if (!session) {
    notFound();
  }

  return <SessionViewer session={session} />;
}

Server Component Flow:

User/crawler requests session URL
Next.js server executes page as async Server Component
Server calls cwc-storage API to fetch session data
Server renders full React tree to HTML
Server returns complete HTML with metadata
Client receives fully-rendered page (no hydration for static content)

SEO Best Practices - CRITICAL

Metadata API (App Router)

Use Next.js Metadata API for every page:

// Static metadata (for non-dynamic pages)
export const metadata: Metadata = {
  title: 'Coding with Claude',
  description: 'Browse developer projects and AI coding sessions',
};

// Dynamic metadata (for pages with dynamic content)
export async function generateMetadata({ params }: PageProps): Promise<Metadata> {
  const data = await fetchData(params);
  return {
    title: data.title,
    description: data.description,
    openGraph: { ... },
    twitter: { ... },
  };
}

Structured Data (JSON-LD)

Include JSON-LD structured data for rich snippets:

// src/components/session/SessionJsonLd.tsx
import type { CwcCodingSession } from 'cwc-types';

type SessionJsonLdProps = {
  session: CwcCodingSession;
  url: string;
};

export function SessionJsonLd({ session, url }: SessionJsonLdProps) {
  const jsonLd = {
    '@context': 'https://schema.org',
    '@type': 'TechArticle',
    headline: session.summary,
    description: session.description,
    datePublished: session.startTimestamp,
    dateModified: session.endTimestamp,
    author: {
      '@type': 'Person',
      name: session.username,
    },
    publisher: {
      '@type': 'Organization',
      name: 'Coding with Claude',
    },
  };

  return (
    <script
      type="application/ld+json"
      dangerouslySetInnerHTML={{ __html: JSON.stringify(jsonLd) }}
    />
  );
}

Sitemap Generation

Use Next.js sitemap generation:

// src/app/sitemap.ts
import type { MetadataRoute } from 'next';
import { cwcApiClient } from '@/lib/cwc-api-client';

export default async function sitemap(): Promise<MetadataRoute.Sitemap> {
  const sessions = await cwcApiClient.listPublishedSessions();

  return sessions.map((session) => ({
    url: `https://codingwithclaude.dev/project/${session.projectId}/session/${session.sessionId}`,
    lastModified: new Date(session.endTimestamp),
    changeFrequency: 'monthly',
    priority: 0.8,
  }));
}

Integration with cwc-storage

Fetching Session Data

cwc-storage acts as proxy to actual storage (filesystem, S3, etc.):

// src/lib/cwc-storage-client.ts
import type { CwcCodingSession } from 'cwc-types';

const STORAGE_API_URL = process.env.CWC_STORAGE_API_URL;
const STORAGE_API_KEY = process.env.CWC_STORAGE_API_KEY;

export const cwcStorageClient = {
  async getSession(sessionId: string): Promise<CwcCodingSession | undefined> {
    const response = await fetch(`${STORAGE_API_URL}/api/sessions/${sessionId}`, {
      headers: {
        Authorization: `Bearer ${STORAGE_API_KEY}`,
      },
      next: { revalidate: 3600 }, // Cache for 1 hour
    });

    if (!response.ok) {
      if (response.status === 404) {
        return undefined;
      }
      throw new Error(`Failed to fetch session: ${response.statusText}`);
    }

    const sessionData = await response.json();

    if (sessionData.formatVersion !== '1.0.0') {
      throw new Error(`Unsupported format version: ${sessionData.formatVersion}`);
    }

    return sessionData as CwcCodingSession;
  },
};

Performance Considerations

Request-Level Caching

Next.js automatically deduplicates fetch requests:

// These two fetches in the same request are deduped automatically
const session1 = await cwcStorageClient.getSession(sessionId);
const session2 = await cwcStorageClient.getSession(sessionId); // Uses cached result

Revalidation Strategy

Use time-based revalidation for session data:

fetch(url, {
  next: {
    revalidate: 3600, // Revalidate every hour
  },
});

Note: Session content is immutable after upload, so aggressive caching is safe.

Session Content Rendering

Component Hierarchy

<SessionPage>             # Server Component - fetches data
  <SessionHeader>         # Title, metadata, stats
  <SessionLayout>         # Two-pane layout
    <ConversationPane>    # Left side (40%)
      <Message>           # User or assistant message
        <MessageContent>  # Markdown rendering
        <ToolUse>         # Tool invocation display
        <ToolResult>      # Tool output (collapsible)
    <FilesPane>           # Right side (60%)
      <FileTree>          # Hierarchical file list
      <FileViewer>        # Code with syntax highlighting
      <DiffViewer>        # Side-by-side diff

Client Components for Interactivity

Mark interactive components with 'use client':

// src/components/session/CollapsibleSection.tsx
'use client';

import { useState } from 'react';

export function CollapsibleSection({ title, children }) {
  const [isOpen, setIsOpen] = useState(false);
  // ...
}

Interactive features requiring Client Components:

Collapsible thinking/tool result sections
File tree expand/collapse
Copy code to clipboard buttons
Tab switching between files

Session Data Format Version Handling

Version-Aware Loading

Support multiple format versions for backward compatibility:

function parseSession(json: unknown): CwcCodingSession {
  const data = json as { formatVersion: string };

  switch (data.formatVersion) {
    case '1.0.0':
      return parseV1(data);
    default:
      console.warn(`Unsupported format version: ${data.formatVersion}`);
      return parseV1(data); // Attempt legacy parser
  }
}

What to Check During Planning

Before implementing session viewing features:

Data format compatibility: Ensure CwcCodingSession type matches JSON from cwc-storage
Server Component boundaries: Identify which components need interactivity (Client)
SEO validation: Test with Google Rich Results Test, validate metadata
Responsive design: Verify layouts work across screen sizes
Error handling: Use Next.js error boundaries and notFound() appropriately

};

export function SessionHeader({ session }: SessionHeaderProps): ReactNode {
  return (
    <header>
      <h1>{session.summary}</h1>
    </header>
  );
}

Page Patterns

Dynamic Route with Metadata

// src/app/project/[projectId]/session/[sessionId]/page.tsx
import type { Metadata } from 'next';
import { notFound } from 'next/navigation';

type PageProps = {
  params: Promise<{ projectId: string; sessionId: string }>;
};

// Dynamic metadata for SEO
export async function generateMetadata({ params }: PageProps): Promise<Metadata> {
  const { sessionId } = await params;
  const session = await fetchSession(sessionId);

  if (!session) {
    return { title: 'Not Found' };
  }

  return {

  };
}

// Page component (Server Component by default)
export default async function SessionPage({ params }: PageProps) {
  const { sessionId } = await params;
  const session = await fetchSession(sessionId);

  if (!session) {
    notFound();
  }

  return <SessionViewer session={session} />;
}

Static Metadata

// src/app/page.tsx
import type { Metadata } from 'next';

export const metadata: Metadata = {
  title: 'Coding with Claude',
  description: 'Browse developer projects and AI coding sessions',
};

export default function HomePage() {
  return <main>...</main>;
}

Data Fetching Patterns

API Client Pattern

// src/lib/cwc-storage-client.ts
import type { CwcCodingSession } from 'cwc-types';

const STORAGE_API_URL = process.env.CWC_STORAGE_API_URL;

export const cwcStorageClient = {
  async getSession(sessionId: string): Promise<CwcCodingSession | undefined> {
    const response = await fetch(`${STORAGE_API_URL}/api/sessions/${sessionId}`, {
      next: { revalidate: 3600 }, // Cache 1 hour
    });

    if (!response.ok) {
      if (response.status === 404) return undefined;
      throw new Error(`Failed to fetch: ${response.statusText}`);
    }

    return response.json();
  },
};

Caching Rules

Data Type	Revalidation	Rationale
Session content	3600s (1 hour)	Immutable after upload
User profiles	300s (5 min)	Occasionally updated
Project list	60s (1 min)	Frequently updated

Client Component Rules

Only use 'use client' when component needs:

useState, useEffect, useRef
Event handlers (onClick, onChange)
Browser APIs (localStorage, window)

// ✅ Needs 'use client' - has state
'use client';

import { useState } from 'react';

export function Collapsible({ children }: Props) {
  const [open, setOpen] = useState(false);
  return (
    <div>
      <button onClick={() => setOpen(!open)}>Toggle</button>
      {open && children}
    </div>
  );
}

// ❌ Does NOT need 'use client' - pure render
export function Badge({ label }: Props) {
  return <span className="badge">{label}</span>;
}

Error Handling

Route Error Boundary

// src/app/project/[projectId]/error.tsx
'use client'; // Error boundaries must be Client Components

type ErrorProps = {
  error: Error;
  reset: () => void;
};

export default function Error({ error, reset }: ErrorProps) {
  return (
    <div>
      <h2>Something went wrong</h2>
      <button onClick={reset}>Try again</button>
    </div>
  );
}

Not Found

// In page component
import { notFound } from 'next/navigation';

if (!data) {
  notFound(); // Renders src/app/not-found.tsx
}

What to Check During Planning

Server vs Client Component: Does this component need interactivity? If no, keep as Server Component
Metadata: Does this page need dynamic SEO metadata? Use generateMetadata
Data fetching: Is caching strategy appropriate for data freshness needs?
Error states: Is there an error boundary for this route?
Loading states: Should there be a loading.tsx for slow data fetches?
Types: Are props typed correctly with cwc-types?

Common Mistakes to Avoid

Mistake	Correct Approach
Adding 'use client' to pages	Keep pages as Server Components, extract interactive parts
Fetching in Client Components	Fetch in Server Components, pass data as props
Missing metadata	Every public page needs title/description
Using `useEffect` for data	Use async Server Components instead
Hardcoding URLs	Use environment variables

Environment Variables

# Required
CWC_STORAGE_API_URL=http://localhost:5030
CWC_API_URL=http://localhost:5040

# Optional
CWC_STORAGE_API_KEY=...  # If storage requires auth

Access in Server Components:

const url = process.env.CWC_STORAGE_API_URL; // ✅ Works

Access in Client Components:

const url = process.env.NEXT_PUBLIC_API_URL; // Must use NEXT_PUBLIC_ prefix

`CWC_API_URL`	URL to cwc-api service	Server only
`NEXT_PUBLIC_APP_URL`	Public URL of the website	Client accessible

Access patterns:

// Server Components - direct access
const apiUrl = process.env.CWC_API_URL;

// Client Components - must use NEXT_PUBLIC_ prefix
const appUrl = process.env.NEXT_PUBLIC_APP_URL;

Rule: Never hardcode URLs. Always use environment variables.

  session: CwcCodingSession;
};

export function SessionHeader({ session }: SessionHeaderProps): ReactNode {
  return (
    <header>
      <h1>{session.summary}</h1>
    </header>
  );
}

Page Patterns

Dynamic Route with Metadata

// src/app/project/[projectId]/session/[sessionId]/page.tsx
import type { Metadata } from 'next';
import { notFound } from 'next/navigation';

type PageProps = {
  params: Promise<{ projectId: string; sessionId: string }>;
};

// Dynamic metadata for SEO
export async function generateMetadata({ params }: PageProps): Promise<Metadata> {
  const { sessionId } = await params;
  const session = await fetchSession(sessionId);

  if (!session) {
    return { title: 'Not Found' };
  }

  return {
    title: session.summary,
    description: session.description,
    openGraph: {
      title: session.summary,
      type: 'article',
    },
  };
}

// Page component (Server Component by default)
export default async function SessionPage({ params }: PageProps) {
  const { sessionId } = await params;
  const session = await fetchSession(sessionId);

  if (!session) {
    notFound();
  }

  return <SessionViewer session={session} />;
}

Static Metadata

// src/app/page.tsx
import type { Metadata } from 'next';

export const metadata: Metadata = {
  title: 'Coding with Claude',
  description: 'Browse developer projects and AI coding sessions',
};

export default function HomePage() {
  return <main>...</main>;
}

Data Fetching Patterns

API Client Pattern

// src/lib/cwc-api-client.ts
import type { CwcProject } from 'cwc-types';

const API_URL = process.env.CWC_API_URL;

export const cwcApiClient = {
  async getProject(projectId: string): Promise<CwcProject | undefined> {
    const response = await fetch(`${API_URL}/api/v1/project/${projectId}`, {
      next: { revalidate: 60 }, // Cache 1 minute
    });

    if (!response.ok) {
      if (response.status === 404) return undefined;
      throw new Error(`Failed to fetch: ${response.statusText}`);
    }

    return response.json();
  },
};

Caching Rules

Data Type	Revalidation	Rationale
Session content	3600s (1 hour)	Immutable after upload
User profiles	300s (5 min)	Occasionally updated
Project list	60s (1 min)	Frequently updated

Client Component Rules

Only use 'use client' when component needs:

useState, useEffect, useRef
Event handlers (onClick, onChange)
Browser APIs (localStorage, window)

// ✅ Needs 'use client' - has state
'use client';

import { useState } from 'react';

export function Collapsible({ children }: Props) {
  const [open, setOpen] = useState(false);
  return (
    <div>
      <button onClick={() => setOpen(!open)}>Toggle</button>
      {open && children}
    </div>
  );
}

// ❌ Does NOT need 'use client' - pure render
export function Badge({ label }: Props) {
  return <span className="badge">{label}</span>;
}

Error Handling

Route Error Boundary

// src/app/project/[projectId]/error.tsx
'use client'; // Error boundaries must be Client Components

type ErrorProps = {
  error: Error;
  reset: () => void;
};

export default function Error({ error, reset }: ErrorProps) {
  return (
    <div>
      <h2>Something went wrong</h2>
      <button onClick={reset}>Try again</button>
    </div>
  );
}

Not Found

// In page component
import { notFound } from 'next/navigation';

if (!data) {
  notFound(); // Renders src/app/not-found.tsx
}

What to Check During Planning

Server vs Client Component: Does this component need interactivity? If no, keep as Server Component
Metadata: Does this page need dynamic SEO metadata? Use generateMetadata
Data fetching: Is caching strategy appropriate for data freshness needs?
Error states: Is there an error boundary for this route?
Loading states: Should there be a loading.tsx for slow data fetches?
Types: Are props typed correctly with cwc-types?

Common Mistakes to Avoid

Mistake	Correct Approach
Adding 'use client' to pages	Keep pages as Server Components, extract interactive parts
Fetching in Client Components	Fetch in Server Components, pass data as props
Missing metadata	Every public page needs title/description
Using `useEffect` for data	Use async Server Components instead
Hardcoding URLs	Use environment variables

Environment Variables

Setup: Copy .env.local.example to .env.local for local development.

Variable	Purpose	Server/Client
`CWC_API_URL`	URL to cwc-api service	Server only
`NEXT_PUBLIC_APP_URL`	Public URL of the website	Client accessible

Access patterns:

// Server Components - direct access
const apiUrl = process.env.CWC_API_URL;

// Client Components - must use NEXT_PUBLIC_ prefix
const appUrl = process.env.NEXT_PUBLIC_APP_URL;

Rule: Never hardcode URLs. Always use environment variables.

Deployment (Future - Not Yet Implemented)

Key Difference from Backend Services

Next.js requires environment variables at BUILD time, not runtime.

Service Type	When Env Vars Needed	How Currently Handled
Backend (cwc-api, etc.)	Runtime (`docker run -e`)	Passed via docker run flags
Next.js (cwc-website)	Build time (`next build`)	Must be in `.env` during docker build

Docker Deployment Pattern for Next.js

# Environment file must be present BEFORE next build
COPY .env.production .env.production
RUN npm run build

# Built app has env vars baked in
CMD ["npm", "start"]

Deployment Workflow (When Implemented)

cwc-deployment copies {env}.cwc-website.env from cwc-secrets to build context
Dockerfile copies env file and runs next build
Environment variables are baked into the JavaScript bundle
Container runs next start (no runtime env injection needed)

Env Files in cwc-secrets

Follow the existing naming convention:

dev.cwc-website.env
test.cwc-website.env
prod.cwc-website.env

Location: ~/coding-with-claude/private/cwc-secrets/env/

Prerequisites Before Deployment

cwc-content service - Must be implemented first (handles auth + content access)
cwc-deployment updates - Add website service type to deployment CLI

Related Packages

Depends On:

cwc-types - Type definitions (CwcCodingSession, etc.)
cwc-api - Authentication and user data
cwc-content - Content access with auth (future - not yet implemented)

Deployed By:

cwc-deployment - Docker deployment CLI (website support not yet implemented)

SEO - Full HTML rendered on server for search crawlers
Performance - No JavaScript bundle for static content
Data Fetching - Async data loading without client-side effects

Client Components

Used only when interactivity is required:

Collapsible sections (thinking blocks, tool results)
File tree navigation
Copy-to-clipboard buttons
Tab switching

Mark with 'use client' directive at the top of the file.

SEO

Metadata

Each page exports metadata for search engines:

export const metadata: Metadata = {
  title: 'Page Title',
  description: 'Page description for search results',
  openGraph: { /* social sharing */ },
};

Dynamic pages use generateMetadata() for data-dependent metadata.

Sitemap

The sitemap is generated at /sitemap.xml using Next.js conventions:

// src/app/sitemap.ts
export default async function sitemap(): Promise<MetadataRoute.Sitemap> {
  // Fetch published sessions and generate URLs
}
