Deploy Pages

wrangler pages deploy ./dist

Deploy Worker

wrangler deploy


## Cloudflare Pages

### Deploy Static Site
```bash
# One-time deploy
wrangler pages deploy ./dist --project-name=my-app

# Connect Git repo (auto-deploy)
wrangler pages project create my-app --production-branch=main

Build Configuration

# wrangler.toml (Pages Functions)
name = "my-app"
compatibility_date = "2025-01-01"

[build]
command = "npm run build"

Cloudflare Workers

Worker Configuration

# wrangler.toml
name = "my-worker"
main = "src/index.ts"
compatibility_date = "2025-01-01"

[vars]
ENVIRONMENT = "production"

[[kv_namespaces]]
binding = "MY_KV"
id = "abc123"

Basic Worker

export default {
  async fetch(request, env, ctx) {
    return new Response('Hello from the edge!', {
      headers: { 'Content-Type': 'text/plain' }
    });
  }
};

Environment & Secrets

# Set secret (encrypted)
wrangler secret put API_KEY

# Set variable (plain text)
wrangler pages secret put API_URL

# Bulk upload
echo "SECRET_KEY" | wrangler secret put SECRET_KEY

DNS Management

# List DNS records
wrangler dns list example.com

# Add A record
wrangler dns create example.com --type A --name www --content 1.2.3.4

# Update record
wrangler dns update example.com --type A --name www --content 5.6.7.8

Deployment Workflow

1. Initialize Project

wrangler init my-project
cd my-project

2. Develop Locally

wrangler dev

3. Deploy

# Production
wrangler deploy

# Preview
wrangler deploy --env staging

Best Practices

Use Environments: Separate staging and production
Versioning: Rollback via dashboard if needed
Edge Caching: Leverage Cache API for performance
Rate Limiting: Protect Workers with rate limits
Monitoring: Enable Workers Analytics

Common Commands

# View logs (tail)
wrangler tail

# List deployments
wrangler deployments list

# Rollback
wrangler rollback --message "Revert breaking change"

# KV operations
wrangler kv:key put --binding=MY_KV "key" "value"
wrangler kv:key get --binding=MY_KV "key"

Anti-Patterns

Don't store secrets in wrangler.toml (use wrangler secret)
Don't deploy without testing locally (wrangler dev)
Don't ignore compatibility_date (affects runtime behavior)
Don't use Workers for long-running tasks (30s limit)
