Electron 🔗 Vite

English | 简体中文

• 🚀 Fully compatible with Vite and Vite's ecosystem _{^{(Based on Vite)}}
• 🎭 Flexible configuration
• 🐣 Few APIs, easy to use
• 🔥 Hot restart

Install

npm i vite-plugin-electron -D

Examples

• quick-start
• custom-start-electron-app
• bytecode

Usage

vite.config.ts

import electron from 'vite-plugin-electron'

export default {
  plugins: [
    electron({
      entry: 'electron/main.ts',
    }),
  ],
}

You can use process.env.VITE_DEV_SERVER_URL when the vite command is called 'serve'

// electron main.js
const win = new BrowserWindow({
  title: 'Main window',
})

if (process.env.VITE_DEV_SERVER_URL) {
  win.loadURL(process.env.VITE_DEV_SERVER_URL)
} else {
  // load your file
  win.loadFile('yourOutputFile.html');
}

API _^(Define)

electron(config: Configuration | Configuration[])

export interface Configuration {
  /**
   * Shortcut of `build.lib.entry`
   */
  entry?: import('vite').LibraryOptions['entry']
  vite?: import('vite').InlineConfig
  /**
   * Triggered when Vite is built every time -- `vite serve` command only.
   * 
   * If this `onstart` is passed, Electron App will not start automatically.  
   * However, you can start Electroo App via `startup` function.  
   */
  onstart?: (this: import('rollup').PluginContext, options: {
    /**
     * Electron App startup function.  
     * It will mount the Electron App child-process to `process.electronApp`.  
     * @param argv default value `['.', '--no-sandbox']`
     */
    startup: (argv?: string[]) => Promise<void>
    /** Reload Electron-Renderer */
    reload: () => void
  }) => void | Promise<void>
}

JavaScript API

vite-plugin-electron's JavaScript APIs are fully typed, and it's recommended to use TypeScript or enable JS type checking in VS Code to leverage the intellisense and validation.

• Configuration - type
• defineConfig - function
• resolveViteConfig - function, Resolve the default Vite's InlineConfig for build Electron-Main
• withExternalBuiltins - function
• build - function
• startup - function

Example

build(
  withExternalBuiltins( // external Node.js builtin modules
    resolveViteConfig( // with default config
      {
        entry: 'foo.ts',
        vite: {
          mode: 'foo-mode', // for .env file
          plugins: [{
            name: 'plugin-build-done',
            closeBundle() {
              // Startup Electron App
              startup()
            },
          }],
        },
      }
    )
  )
)

How to work

It just executes the electron . command in the Vite build completion hook and then starts or restarts the Electron App.

Recommend structure

Let's use the official template-vanilla-ts created based on create vite as an example

+ ├─┬ electron
+ │ └── main.ts
  ├─┬ src
  │ ├── main.ts
  │ ├── style.css
  │ └── vite-env.d.ts
  ├── .gitignore
  ├── favicon.svg
  ├── index.html
  ├── package.json
  ├── tsconfig.json
+ └── vite.config.ts

Be aware

• 🚨 By default, the files in electron folder will be built into the dist-electron
• 🚨 Currently, "type": "module" is not supported in Electron
• 🚨 In general, Vite may not correctly build Node.js packages, especially C/C++ native modules, but Vite can load them as external packages. So, put your Node.js package in dependencies. Unless you know how to properly build them with Vite.

  electron({
    entry: 'electron/main.ts',
    vite: {
      build: {
        rollupOptions: {
          // Here are some C/C++ plugins that can't be built properly.
          external: [
            'serialport',
            'sqlite3',
          ],
        },
      },
    },
  }),
