Quick Start — Functions

Go from zero to a deployed Function in under 2 minutes.

Prerequisites

• Node.js 18+
• An Aerostack account (sign up free)

1. Install the CLI

   npm install -g @aerostack/cli

2. Log in

   aerostack login

3. Create a new function

   From a template

   Pick a template to start with a working app:

   # REST API with Hono + D1 database
   aerostack init my-app --template api
   
   # REST API with Neon PostgreSQL
   aerostack init my-app --template api-neon
   
   # WebSocket group chat
   aerostack init my-app --template ws-chat
   
   # Conversational AI agent
   aerostack init my-app --template ws-voice-agent
   
   # SSE AI streaming
   aerostack init my-app --template ai-stream
   
   # Multiplayer game state sync
   aerostack init my-app --template ws-multiplayer-game

   See all 8 templates: Templates

   Blank project

   Start with a clean project:

   aerostack init my-app
   cd my-app

   This creates:

   my-app/
   ├── src/
   │   └── index.ts          ← Your function code
   ├── aerostack.toml        ← Configuration
   ├── package.json
   └── tsconfig.json

4. Run locally

   cd my-app
   npm install
   aerostack dev

   Your function is running at http://localhost:8787. All platform bindings (DB, Cache, Queue, AI, Vector Search, Storage) work locally out of the box.

5. Deploy

   aerostack deploy function

   That’s it. Your function is live on Cloudflare’s edge in 300+ data centers. The CLI outputs your live URL.

   Deploying function: my-app
     Building... done (1.2s)
     Uploading... done
     Bindings configured:
       DB        → aerostack-core (Database)
       CACHE     → project-cache (Cache)
       QUEUE     → project-queue (Queue)
       AI        → Workers AI
       VECTORIZE → project-vectors (Vector Search)
       STORAGE   → project-storage (Storage)
   
     Live at: https://my-app.your-project.aerostack.dev

What just happened?

1. aerostack init scaffolded a TypeScript project with aerostack.toml configuration
2. aerostack dev started a local dev server with all 6 platform bindings simulated locally
3. aerostack deploy uploaded your code to Cloudflare’s edge, wired up real bindings, and gave you a URL

No Docker. No Kubernetes. No infrastructure config. One command to develop, one command to deploy.
