Run Bun on Vercel Serverless Functions

https://bun-vercel.vercel.app/

This is an experimental project and should not be used in production. This project is not endorsed by Vercel.

// src/main.ts
import { type Server } from "bun"

export default {
  async fetch(request: Request, server: Server) {
    return new Response("Hello from Bun on Vercel", {
      status: 200,
      headers: { "Content-Type": "text/plain" }
    })
  }
}

Get Started

There are two ways to deploy your project to Vercel:

1. GitHub integration
2. Manually from your computer

GitHub Integration

Note: An issue in Bun must be resolved before this method is fully operational

1. Update your package.json with bun-vercel

{
  "devDependencies": {
    "bun-vercel": "^1.0.0-alpha.4",
  }
}

2. Update the build script run bun-vercel

{
  "scripts": {
    "build": "bun-vercel ./src/main.ts"
  }
}

3. Add a vercel.json with your build command

{
  "buildCommand": "bun run build"
}

Manually

Before starting you should follow the same setup steps as the GitHub integration, as they will be needed regardless.

Note: To deploy from your computer you must have Docker installed so we can build for Amazon Linux

1. Install the Vercel CLI and run vercel link
2. Run bun run build
3. Run vercel deploy --prebuilt --prod
