Electron 打包 React项目

本篇内容将记录并介绍使用Electron来打包已有的React项目；

1、安装Electron

npm install -g electron
npm install -D electron
  • 我这里使用的是全局安装electron，原因是因为electron包比较大，而且运行Electron这一操作是可复用的，所以我认为全局安装electron更加合适，这里只需要安装一次electron，在哪里都能使用。

2、相关配置

  1. 在根目录添加 main.js文件

    // Modules to control application life and create native browser window
const {app, BrowserWindow} = require('electron');
const path = require('path');
const url = require('url');

// Keep a global reference of the window object, if you don't, the window will
// be closed automatically when the JavaScript object is garbage collected.
let mainWindow;

function createWindow () {
  // Create the browser window.
  mainWindow = new BrowserWindow({
    width: 800,
    height: 600,
    webPreferences: {
      preload: path.join(__dirname, 'preload.js'),
    },
  });

  // 加载应用----适用于 react 项目
 mainWindow.loadURL('http://localhost:3000/');

  // 打开开发者工具，默认不打开
  // mainWindow.webContents.openDevTools()

  // Open the DevTools.
  // mainWindow.webContents.openDevTools()

  // Emitted when the window is closed.
  mainWindow.on('closed', function () {
    // Dereference the window object, usually you would store windows
    // in an array if your app supports multi windows, this is the time
    // when you should delete the corresponding element.
    mainWindow = null;
  });
}

// This method will be called when Electron has finished
// initialization and is ready to create browser windows.
// Some APIs can only be used after this event occurs.
app.on('ready', createWindow);

// Quit when all windows are closed.
app.on('window-all-closed', function () {
  // On macOS it is common for applications and their menu bar
  // to stay active until the user quits explicitly with Cmd + Q
  if (process.platform !== 'darwin') app.quit();
});

app.on('activate', function () {
  // On macOS it's common to re-create a window in the app when the
  // dock icon is clicked and there are no other windows open.
  if (mainWindow === null) createWindow();
});

// In this file you can include the rest of your app's specific main process
// code. You can also put them in separate files and require them here.

  2. 修改package.json配置

    • 将刚刚配置的main.js文件配置到package的”main”: “main.js”

    • 默认情况下，homepage 是 http://localhost:3000，build 后，所有资源文件路径都是 /static，而 Electron 调用的入口是 file :协议，/static 就会定位到根目录去，所以找不到静态文件。在 package.json 文件中添加 homepage 字段并设置为”.”后，静态文件的路径就变成了相对路径，就能正确地找到了添加如下配置：

      “homepage”:”.”

    • 配置

          {
      "name": "rui",

      },
      "babel": {
          "presets": [

          ]
      },
      "devDependencies": {

          "type": "git",
          "url": "git@github.com:realRoyHsu/rui.git"
      }
  }

  3. 在根目录添加preload.js文件

        // All of the Node.js APIs are available in the preload process.
      // It has the same sandbox as a Chrome extension.
      window.addEventListener('DOMContentLoaded', () => {
        const replaceText = (selector, text) => {
          const element = document.getElementById(selector);
          if (element) element.innerText = text;
        };

        for (const type of ['chrome', 'node', 'electron']) {
          replaceText(`${type}-version`, process.versions[type]);
        }
      });

3、启动 Electron

# 启动react项目
npm start
# 启动electron
npm run electron:start

注意：启动electron应用后，如何无法显示index页面,可能是你路由配置了BrowserRouter模式，请改成HashRouter。VUE项目出不来的话，很大可能是使用了history路由模式，改成hash路由模式就可以了。

4、打包

  • 注意：要修改跟目录下面的main.js文件

    //   加载应用----react 打包
     mainWindow.loadURL(url.format({
         pathname: path.join(__dirname, './build/index.html'),
         protocol: 'file:',
         slashes: true,
     }));
// 加载应用----适用于 react 开发配置
// mainWindow.loadURL('http://localhost:3000/');

  • 将你配置的main.js、package.json、preload.js,复制一份到public静态文件中，不然打包后，还是会无法打开程序。
    注意：修改public中的main.js pathname: path.join(__dirname, './index.html')

    //   加载应用----react 打包
     mainWindow.loadURL(url.format({
         pathname: path.join(__dirname, './index.html'),
         protocol: 'file:',
         slashes: true,
     }));
// 加载应用----适用于 react 开发配置
// mainWindow.loadURL('http://localhost:3000/');

  • 安装electron-packager

    # 根目录下安装electron-packager包
npm install electron-packager --save-dev
# 安装electron-packager命令
npm install electron-packager -g

  • electron-packager命令介绍

    electron-packager <location of project> <name of project> <platform> <architecture> <electron version> <optional options>
    • location of project: 项目的本地地址，此处我这边是 ~/knownsec-fed
    • location of project: 项目名称，此处是 knownsec-fed
    • platform: 打包成的平台
    • architecture: 使用 x86 还是 x64 还是两个架构都用
    • electron version: electron 的版本

  • 配置package.json打包脚本

    “electron:build”: “electron-packager ./build rui –platform=win32 –arch=x64 –out=./../out –ar –app-version=0.0.1 –electron-version=6.0.1”,

  • 开始打包

    先编译出静态资源
npm run build
在编译electron
npm run electron:build

找到打包文件中exe文件，双击打开运行

5、asar压缩

"electron:build": "electron-packager ./build rui --platform=win32 --arch=x64 --out=./../out --app-version=0.0.1 --asar --electron-version=6.0.1",

6、使用inno来编译打包好的文件
