Railway

For a simple Bun server deployment you can use Railway by changing just a few lines of code.

Update app export

Update the code inside server/src/index.ts and use the export below which gives Railway access to the host and port.

srver/src/index.ts
import { Hono } from 'hono'
import { cors } from 'hono/cors'
import type { ApiResponse } from 'shared/dist'
 
const app = new Hono()
 
app.use(cors())
 
app.get('/', (c) => {
  return c.text('Hello Hono!')
})
 
app.get('/hello', async (c) => {
 
  const data: ApiResponse = {
    message: "Hello BHVR!",
    success: true
  }
 
  return c.json(data, { status: 200 })
})
 
export default app;
export default { 
  port: Number(process.env.PORT) || 3000, 
  hostname: '0.0.0.0', 
  fetch: app.fetch, 
};

Add start command

Inside the root package.json add a new start command that will be used by Railway for deployment

package.json
// Rest of package.json
  "scripts": {
    "dev": "turbo dev",
    "dev:client": "turbo dev --filter=client",
    "dev:server": "turbo dev --filter=server",
    "build": "turbo build",
    "build:client": "turbo build --filter=client",
    "build:server": "turbo build --filter=server",
    "lint": "turbo lint",
    "type-check": "turbo type-check",
    "test": "turbo test",
    "postinstall": "turbo build --filter=shared --filter=server",
    "start": "bun run server/dist/index.js"
  },
