Deploy Elysia on Vercel

Elysia can be deployed on Vercel with zero configuration using either Bun or Node runtime.

1. In src/index.ts, create or import an existing Elysia server
2. Export the Elysia server as the default export

import { Elysia, t } from 'elysia'

export default new Elysia()
    .get('/', () => 'Hello Vercel Function')
    .post('/', {
        body: t.Object({
            name: t.String()
        })
    }, ({ body }) => body)

3. Develop locally with the Vercel CLI

vc dev

4. Deploy to Vercel

vc deploy

That’s it. Your Elysia app is now running on Vercel.

pnpm

If your pnpm configuration does not install peer dependencies, add the peers required by Elysia v2 explicitly:

pnpm add typebox exact-mirror openapi-types

Using Node.js

To deploy with Node.js, make sure to set type: module in your package.json

package.json

{
  "name": "elysia-app",
  "type": "module"
}

Using Bun

To deploy with Bun, make sure to set the runtime to Bun in your vercel.json

vercel.json

{
  "$schema": "https://openapi.vercel.sh/vercel.json",
  "bunVersion": "1.x"
}

If this doesn’t work

Vercel has zero-configuration support for Elysia. For additional configuration, please refer to the Vercel documentation
