Bun Transpiler middleware for Hono

The Bun Transpiler middleware is a Hono middleware designed to transpile content such as TypeScript or TSX. You can place your script written in TypeScript in a directory and serve it using serveStatic. When you apply this middleware, your script will automatically be served transpiled into JavaScript code.

This middleware works only with Bun.

Usage

Installation

npm i @hono/bun-transpiler

Example

import { Hono } from 'hono'
import { serveStatic } from 'hono/bun'
import { bunTranspiler } from '@hono/bun-transpiler'

const app = new Hono()

app.get('/static/:scriptName{.+.tsx?}', bunTranspiler())
app.get('/static/*', serveStatic({ root: './' }))

export default app

Notes

• This middleware does not have a cache feature. If you want to cache the transpiled code, use Cache Middleware or your own custom middleware.
