@stewie-js/adapter-bun

❗ Work in progress.

Stewie is under active development and not yet stable. APIs may change between releases. Not recommended for production use yet.

Bun HTTP adapter for Stewie. Since Bun's Bun.serve() natively speaks Request / Response, this adapter is a thin wrapper that connects your Stewie app handler to Bun.serve().

Part of the Stewie framework.

Install

pnpm add @stewie-js/adapter-bun

The example above also uses @stewie-js/server and @stewie-js/core, which are a common pairing but not required by the adapter itself — it works with any handler that accepts a Request and returns a Response.

Usage

import { createBunHandler } from '@stewie-js/adapter-bun'
import { renderToString } from '@stewie-js/server'
import { jsx } from '@stewie-js/core'
import App from './App.js'

const template = Bun.file('dist/client/index.html').text()

Bun.serve(createBunHandler(async (req) => {
  const { html, stateScript } = await renderToString(jsx(App, {}))
  const page = (await template)
    .replace('<!--ssr-outlet-->', html)
    .replace('</body>', `  ${stateScript}\n</body>`)
  return new Response(page, {
    headers: { 'content-type': 'text/html; charset=utf-8' },
  })
}, { port: 3000 }))
console.log('Listening on http://localhost:3000')

API

| Export | Description | |---|---| | createBunHandler(app, options?) | Returns a BunServeOptions object (including the fetch handler) ready to pass directly to Bun.serve() | | StewieApp | Type: (request: Request) => Response \| Promise<Response> | | BunServeOptions | Type: the serve-options object returned by createBunHandler |

Unhandled errors thrown by the app handler are caught, logged to console.error, and converted to a 500 response automatically.
