Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

  • 支持 esmcjs ,你可以在 electron v28+ 中使用 esm
  • 支持 vuereact 等其他 vite 支持的框架
  • 可选 electron-builder 简单配置打包

安装

# pnpm
pnpm add @tomjs/vite-plugin-electron -D

# yarn
yarn add @tomjs/vite-plugin-electron -D

# npm
npm i @tomjs/vite-plugin-electron --save-dev

如果使用 builder 打包应用,请安装 electron-builder

# pnpm
pnpm add electron-builder -D

# yarn
yarn add electron-builder -D

# npm
npm i electron-builder --save-dev

使用说明

推荐约定

目录结构

  • 推荐 electron 和 页面 src 代码目录结构
|--electron
|  |--main        // main process code
|  |  |--index.ts
|  |--preload     // preload process code
|  |  |--index.ts
|  |--build       // electron-builder resources for electron package
|  |  |--icons
|--src            // front-end code
|  |--App.vue
|  |--main.ts
  • 零配置,默认 dist 输出目录
|--dist
|  |--main
|  |  |--index.js
|  |  |--index.js.map
|  |--preload
|  |  |--index.js
|  |  |--index.js.map
|  |--renderer
|  |  |--index.html

默认配置和行为

详细查看 PluginOptionsrecommended 参数说明

electron

electron/main/index.ts

import { dirname } from 'node:path';
import { fileURLToPath } from 'node:url';
import { app, BrowserWindow } from 'electron';

// when package.json "type": module"
global.__dirname = dirname(fileURLToPath(import.meta.url));

const preload = join(__dirname, '../preload/index.mjs');
const url = process.env.VITE_DEV_SERVER_URL;

async function createWindow() {
  win = new BrowserWindow({
    title: 'Main window',
    width: 800,
    height: 700,
    webPreferences: {
      preload,
      nodeIntegration: true,
      contextIsolation: false,
    },
  });

  if (isDev) {
    win.loadURL(url);
  } else {
    win.loadFile(indexHtml);
  }
}

app.whenReady().then(createWindow);

vue

以使用 esm 为例,不过要求 Electron>=28

  • package.json

Electron preload process 必须使用 .mjs 后缀,否则报错,查看官方文档。所以 preloadesm 默认输出使用 mjs 后缀。为了保持一致性,main process 也以 .mjs 结尾。

{
  "type": "module",
  "main": "dist/main/index.mjs"
}
  • vite.config.ts
import { defineConfig } from 'vite';
// import renderer from 'vite-plugin-electron-renderer'; // 启用 nodeIntegration
import electron from '@tomjs/vite-plugin-electron';
import vue from '@vitejs/plugin-vue';

export default defineConfig({
  plugins: [
    vue(),
    // 如使用约定的目录结构,则不需要配置
    electron(),
    // 如果自定义了目录结构,则必须根据实际情况赋值
    // electron({
    //   main: {
    //     entry: 'electron/main/index.ts',
    //   },
    //   preload: {
    //     entry: 'electron/preload/index.ts',
    //   },
    // }),
    // renderer(),
  ],
});

react

以使用 cjs 为例

  • package.json
{
  // "type": "commonjs",
  "main": "dist/main/index.js"
}
  • vite.config.ts
import { defineConfig } from 'vite';
import electron from '@tomjs/vite-plugin-electron';
import react from '@vitejs/plugin-react-swc';

export default defineConfig({
  plugins: [react(), electron()],
});

文档

参数

PluginOptions

| 参数名 | 类型 | 默认值 | 说明 | | --- | --- | --- | --- | | recommended | boolean | true | 这个选项是为了提供推荐的默认参数和行为 | | external | string[] | | 不打包这些模块,但是 dependencies and peerDependencies 默认排除,详见 | | main | MainOptions | | electron main 进程选项 | | preload | PreloadOptions | | electron preload 进程选项 | | debug | boolean | false | Electron调试模式,不启动Electron。 您还可以使用 process.env.VITE_ELECTRON_DEBUG | | builder | boolean | false | 如果是boolean类型,是否启用electron-builder。如果是Object,则是electron-builder配置。 您还可以使用 process.env.VITE_ELECTRON_DEBUG 开启它。 | | inspect | boolean | false | Electron 将监听指定 port 上的 V8 调试协议消息, 外部调试器需要连接到此端口上。您还可以使用 process.env.VITE_ELECTRON_INSPECT。 有关更多信息,请参阅debugging-main-process。 |

recommended 选项用于设置默认配置和行为,几乎可以达到零配置使用,默认为 true 。如果你要自定义配置,请设置它为false。以下默认的前提条件是使用推荐的 项目结构

  • 检查是否存在 electron/main/index.tselectron/main/index.ts,如果有则分别给 main.entrypreload.entry 赋值。如果不存在,main.entry 必须主动赋值,负责会报错
  • 输出目录根据 vitebuild.outDir 参数, 将 electron/mainelectron/preloadsrc 分别输出到 dist/maindist/preloaddist/renderer
  • 其他待实现的行为

MainOptions

继承自 tsupOptions,添加了一些默认值,方便使用。

| 参数名 | 类型 | 默认值 | 说明 | | --- | --- | --- | --- | | entry | string | - | main 入口文件 | | format | 'cjs' \| 'esm' | - | 打包格式。如果未指定,将使用 package.json 中的 "type" 字段 | | outDir | string | "dist-electron/main" | main 输出文件夹 | | onSuccess | () => Promise<void \| undefined \| (() => void \| Promise<void>)> | undefined | 构建成功后运行的回调函数 |

PreloadOptions

继承自 tsupOptions,添加了一些默认值,方便使用。

| 参数名 | 类型 | 默认值 | 说明 | | --- | --- | --- | --- | | entry | string | - | preload 入口文件 | | format | 'cjs' \| 'esm' | - | 打包格式。如果未指定,将使用 package.json 中的 "type" 字段 | | outDir | string | "dist-electron/preload" | preload 输出文件夹 | | onSuccess | () => Promise<void \| undefined \| (() => void \| Promise<void>)> | undefined | 构建成功后运行的回调函数 |

BuilderOptions

recommendedbuilder.enable 都为 true 时,使用 electron-builder 打包 Electron 应用程序。

  • 在vite中配置的build.outDir目录中,根据配置和package.json生成新的package.json,排除非依赖项。
  • 执行npm install然后打包。

不适合所有人使用。

使用该功能,需要额外安装 electron-builder

| 参数名 | 类型 | 默认值 | 说明 | | --- | --- | --- | --- | | appId | string | "com.electron.${name}" | 应用程序 ID。详细 | | productName | string | `` | 应用程序名称。详细 | | builderConfig | Configuration | undefined | electron-builderConfiguration |

默认配置如下

const config = {
  directories: {
    buildResources: 'electron/build',
    app: path.dirname(resolvedConfig.build.outDir),
    output: 'release/${version}',
  },
  files: ['main', 'preload', 'renderer'],
  artifactName: '${productName}-${version}-${os}-${arch}.${ext}',
  electronDownload: {
    // when npm registry mirror is 'registry.npmmirror.com'
    mirror: 'https://npmmirror.com/mirrors/electron',
  },
  electronLanguages: ['zh-CN', 'en-US'],
  win: {
    target: [
      {
        target: 'nsis',
        arch: ['x64'],
      },
    ],
  },
  mac: {
    target: ['dmg'],
  },
  linux: {
    target: ['zip'],
  },
  nsis: {
    oneClick: false,
    perMachine: false,
    allowToChangeInstallationDirectory: true,
    deleteAppDataOnUninstall: false,
  },
};

补充说明

  • mainpreload 未配置相关参数时的默认值

| 参数 | 开发模式默认值 | 生产模式默认值 | | --------- | -------------- | -------------- | | sourcemap | true | false | | minify | false | true |

环境变量

vite 插件变量

| 变量 | 描述 | | --- | --- | | VITE_ELECTRON_DEBUG | Electron主进程调试,不要启动Electron。 当值为 true 或 1 时启用,为 false 或 0 时禁用。默认值未定义。 | | VITE_ELECTRON_INSPECT | Electron 将在指定端口上侦听 V8 检查器协议消息,外部调试器需要连接到该端口。 当值为 true 时,默认端口为 5858。 | | VITE_ELECTRON_BUILDER | 启用 Electron-builder 进行打包。 当值为 true 或 1 时启用,为 false 或 0 时禁用。 默认值未定义。 |

调试

Web调试

使用 @tomjs/electron-devtools-installer 安装 Chrome Devtools 插件后像 Web 开发一样使用

import { app } from 'electron';

app.whenReady().then(() => {
  const { installExtension, REACT_DEVELOPER_TOOLS, REDUX_DEVTOOLS } = await import(
    '@tomjs/electron-devtools-installer'
  );

  installExtension([REACT_DEVELOPER_TOOLS, REDUX_DEVTOOLS])
    .then(exts => {
      console.log(
        'Added Extension: ',
        exts.map(s => s.name),
      );
    })
    .catch(err => {
      console.log('Failed to install extensions');
      console.error(err);
    });
});

Main Process 调试

通过 vscode 运行 Debug Main Process 调试主线程,调试工具参考 官方文档

launch.json 配置如下:

{
  "version": "0.2.0",
  "configurations": [
    {
      "name": "Debug Main Process",
