Getting Started ​

Prerequisites ​

Create a project ​

bash
bunx create-b3-cf-app

Follow the prompts:

  1. Project directory — where to scaffold (e.g. my-app)
  2. Description — optional project description
  3. bun install — whether to install dependencies immediately
  4. git init — whether to initialize a git repository

Start developing ​

bash
cd my-app

# Terminal 1: Hono API worker (Cloudflare dev)
bun run cf:dev

# Terminal 2: Vite dev server (proxies /api → worker)
bun run --filter @repo/web dev

# Or both at once:
bun run dev

Open the Vite dev server URL (default http://localhost:5173). The home page calls /api/rpc/hello through the typed Hono RPC client.

Deploy ​

bash
bun run cf:deploy

This builds the SPA (bun run --filter @repo/web build) and deploys the Worker with assets to Cloudflare.
