项目推荐

想要快速的了解 electron，调试 electron，打包 electron，推荐项目electron-webpack-quick-start

快速开始

先安装 cross-env，用于设置环境变量。因为在后面安装electron，需要下载，默认的源在国内下载很慢，需要通过设置环境变量来切换下载地址

#安装cross-env，用于设置环境变量的
npm install cross-env -g

Clone项目到本地

# Clone repository
git clone https://github.com/electron-userland/electron-webpack-quick-start.git

进入项目目录

cd electron-webpack-quick-start

安装项目依赖

cross-env ELECTRON_MIRROR="https://npm.taobao.org/mirrors/electron/" npm install

对比 electron 7.0.0，说明下为什么没有设置npm_config_electron_custom_dir 环境变量。该项目用的 electron版本是 5.0.6，所以环境变量只用设置 ELECTRON_MIRROR。可以看下 electron-download文件下的 index.js文件，只有默认 url 里加了 v，设置 ELECTRON_MIRROR 后， url 里不会带 v

 get baseUrl () {
  if (this.version.indexOf('nightly') !== -1) {
   return process.env.NPM_CONFIG_ELECTRON_NIGHTLY_MIRROR ||
    process.env.npm_config_electron_nightly_mirror ||
    process.env.npm_package_config_electron_nightly_mirror ||
    process.env.ELECTRON_NIGHTLY_MIRROR ||
    this.opts.nightly_mirror ||
    'https://github.com/electron/nightlies/releases/download/v'
  }
  return process.env.NPM_CONFIG_ELECTRON_MIRROR ||
   process.env.npm_config_electron_mirror ||
   process.env.npm_package_config_electron_mirror ||
   process.env.ELECTRON_MIRROR ||
   this.opts.mirror ||
   'https://github.com/electron/electron/releases/download/v'
 }

体验打包

我想打包成一个免安装的 exe程序，所以我在 package.json 文件里添加了：

 "build": {
  "productName": "HelloWord",
  "appId": "scripter.HelloWord",
  "win": {
   "target": ["portable"]
  },
  "portable": {
   "artifactName": "HelloWord.exe"
  }
 }

整个 package.json 内容如下：

{
 "name": "electron-webpack-quick-start",
 "version": "0.0.0",
 "license": "MIT",
 "scripts": {
  "dev": "electron-webpack dev",
  "compile": "electron-webpack",
  "dist": "yarn compile && electron-builder",
  "dist:dir": "yarn dist --dir -c.compression=store -c.mac.identity=null"
 },
 "dependencies": {
  "source-map-support": "^0.5.12"
 },
 "devDependencies": {
  "electron": "5.0.6",
  "electron-builder": "^21.0.11",
  "electron-webpack": "^2.7.4",
  "webpack": "~4.35.3"
 },
 "build": {
  "productName": "HelloWord",
  "appId": "scripter.HelloWord",
  "win": {
   "target": ["portable"]
  },
  "portable": {
   "artifactName": "HelloWord.exe"
  }
 }
}
