@hono/vite-build

@hono/vite-build is a set of Vite plugins for building Hono applications with Vite. It supports multiple runtimes and platforms, allowing you to build a project that includes JavaScript files for these platforms from a Hono app.

Here are the modules included:

@hono/vite-build/base
@hono/vite-build/cloudflare-pages
@hono/vite-build/cloudflare-workers
@hono/vite-build/bun
@hono/vite-build/node

Usage

Install

You can install vite and @hono/vite-build via the npm.

npm i -D vite @hono/vite-build

Or you can install them with Bun.

bun add -D vite @hono/vite-build

Settings

Add "type": "module" to your package.json. Then, create vite.config.ts and edit it. The following is for Bun.

import { defineConfig } from 'vite'
import build from '@hono/vite-build/bun'
// import build from '@hono/vite-build/cloudflare-pages'
// import build from '@hono/vite-build/cloudflare-workers'
// import build from '@hono/vite-build/node'

export default defineConfig({
  plugins: [
    build({
      // Defaults are `src/index.ts`,`./src/index.tsx`,`./app/server.ts`
      entry: './src/index.tsx',
    }),
  ],
})

Build

Just run vite build.

npm exec vite build

bunx --bun vite build

Run

Run with the command on your runtime. For examples:

Cloudflare Pages:

wrangler pages dev ./dist

Bun:

cd ./dist
bun run ./index.js

Node.js:

cd ./dist
node ./index.js

Common Options

type BuildOptions = {
  entry?: string | string[]
  output?: string
  outputDir?: string
  external?: string[]
  minify?: boolean
  emptyOutDir?: boolean
}

Default values:

export const defaultOptions = {
  entry: ['src/index.ts', './src/index.tsx', './app/server.ts'],
  output: 'index.js',
  outputDir: './dist',
  external: [],
  minify: true,
  emptyOutDir: false,
  staticPaths: [],
}

Platform specific things

Cloudflare Pages

This plugin generates _routes.json automatically. The automatic generation can be overridden by creating a public/_routes.json. See Create a _routes.json file on Cloudflare Docs for more details.

Example project

src/index.tsx:

import { Hono } from 'hono'

const app = new Hono()

app.get('/', (c) => {
  return c.html(
    <html>
      <head>
        <link href='/static/style.css' rel='stylesheet' />
      </head>
      <body>
        <h1>Hello!</h1>
      </body>
    </html>
  )
})

export default app

public/static/style.css:

h1 {
  font-family: Arial, Helvetica, sans-serif;
}

The project with those file will be built to the following files with @hono/vite-build/bun:

dist
├── index.js
└── static
 └── style.css

Build a client

If you also want to build a client-side script, you can configure it as follows.

export default defineConfig(({ mode }) => {
  if (mode === 'client') {
    return {
      build: {
        rollupOptions: {
          input: './src/client.ts',
          output: {
            dir: './dist/static',
            entryFileNames: 'client.js',
          },
        },
        copyPublicDir: false,
      },
    }
  } else {
    return {
      plugins: [build()],
    }
  }
})

The build command:

vite build --mode client && vite build

import.meta.env.PROD is helpful in detecting whether it is in development or production mode if you are using it on a Vite dev server.

app.get('/', (c) => {
  return c.html(
    <html>
      <head>
        {import.meta.env.PROD ? (
          <script type='module' src='/static/client.js'></script>
        ) : (
          <script type='module' src='/src/client.ts'></script>
        )}
      </head>
      <body>Hello!</body>
    </html>
  )
})
