# C3 (create-cloudflare)
Official CLI for scaffolding Cloudflare Workers and Pages projects with templates, TypeScript, and instant deployment.
## Quick Start
```bash
# Interactive (recommended for first-time)
npm create cloudflare@latest my-app
# Worker (API/WebSocket/Cron)
npm create cloudflare@latest my-api -- --type=hello-world --ts
# Pages (static/SSG/full-stack)
npm create cloudflare@latest my-site -- --type=web-app --framework=astro --platform=pages
```
## Platform Decision Tree
```
What are you building?
├─ API / WebSocket / Cron / Email handler
│ └─ Workers (default) - no --platform flag needed
│ npm create cloudflare@latest my-api -- --type=hello-world
├─ Static site / SSG / Documentation
│ └─ Pages - requires --platform=pages
│ npm create cloudflare@latest my-site -- --type=web-app --framework=astro --platform=pages
├─ Full-stack app (Next.js/Remix/SvelteKit)
│ ├─ Need Durable Objects, Queues, or Workers-only features?
│ │ └─ Workers (default)
│ └─ Otherwise use Pages for git integration and branch previews
│ └─ Add --platform=pages
└─ Convert existing project
└─ npm create cloudflare@latest . -- --type=pre-existing --existing-script=./src/worker.ts
```
**Critical:** Pages projects require `--platform=pages` flag. Without it, C3 defaults to Workers.
## Interactive Flow
When run without flags, C3 prompts in this order:
1. **Project name** - Directory to create (defaults to current dir with `.`)
2. **Application type** - `hello-world`, `web-app`, `demo`, `pre-existing`, `remote-template`
3. **Platform** - `workers` (default) or `pages` (for web apps only)
4. **Framework** - If web-app: `next`, `remix`, `astro`, `react-router`, `solid`, `svelte`, etc.
5. **TypeScript** - `yes` (recommended) or `no`
6. **Git** - Initialize repository? `yes` or `no`
7. **Deploy** - Deploy now? `yes` or `no` (requires `wrangler login`)
## Installation Methods
```bash
# NPM
npm create cloudflare@latest
# Yarn
yarn create cloudflare
# PNPM
pnpm create cloudflare@latest
```
