Bun Plugin Vue

A simple Vue plugin for Bun build, dev server etc. Made to be able to load SFC's into bun's bundler.

Important

This module is only compatible with the Bun Runtime.

• Script
• Script Setup
• Script with TS
• Styles
• Scoped Styles
• Template

Installation

bun add -D @killusions/bun-plugin-vue

Typing Vue

If you want to have Vue's types, add a vue-shim.d.ts file to the root of your project:

// vue-shim.d.ts
declare module '*.vue' {
  import type { DefineComponent } from 'vue';
  const component: DefineComponent<object, object, any>;
  export default component;
}

Usage

The following is a quickstart, but see the examples directory for full examples.

In Bun Build

import vuePlugin from '@killusions/bun-plugin-vue'

Bun.build({
  // index.html Imports main.ts where App.vue is setup
  entrypoints: ['./index.html'],
  outdir: './dist',
  plugins: [vuePlugin()],
})

In Bun Full-Stack Dev Server

First create the local plugin file:

// vue-plugin.ts
import vuePlugin from '@killusions/bun-plugin-vue'
export default vuePlugin()

Then update bunfig.toml

[serve.static]
plugins = ["./vue-plugin.ts"]

Plugin Options

The plugin has optional settings that you can pass:

interface VuePluginOptions {
  prodDevTools?: boolean; // Default = false
  optionsApi?: boolean; // Default = false
  prodHydrationMismatchDetails?: boolean; // Default = false
}

• prodDevTools: If set to true, it will enable Vue DevTools in production mode. This is useful for debugging but may expose sensitive information, so use with caution.
• optionsApi: If set to true, it will enable the Options API in Vue. This is useful if you want to use the Options API instead of the Composition API.
• prodHydrationMismatchDetails: If set to true, it will provide detailed error messages for hydration mismatches in production mode. This is useful for debugging hydration issues but may expose sensitive information, so use with caution.

Known Issues

Hot Reloading Error Logs

Because bun implements hot reloading in the Full-Stack Dev Server to eliminate HMR error logs, add the following to the main.ts where your vue app is created:

import { createApp } from 'vue';
import App from './App.vue';

const app = createApp(App);

// The important part for HMR
if (import.meta.hot) {
  import.meta.hot.on('bun:invalidate', () => {
    app.unmount();
  })
  import.meta.hot.accept()
}

app.mount('#app');

This HMR code will be dead-code eliminated during production.
