Gulp-webpack简单应用

1.配置环境：  在  webstorm  的控制台中  (1) cnpm install --save-dev gulp    (2)  cnpm install --save-dev gulp-webpack

(3)cnpm install babel-loader babel-core babel-preset-es2017 --save-dev

2.目录结构：(  build文件夹 是在配置好所有文件后，在webstorm的控制台输入  gulp  后自动生成的)

3.gulpfile文件配置：

 /**
  * Created by Administrator on 2016/11/16.
  */

 const gulp = require("gulp");
 const webpack = require("gulp-webpack");

 gulp.task("copy_html_files", function () {
     gulp.src("src/**/*.html").pipe(gulp.dest("build"));
 });

 gulp.task("copy_package_json", function () {
     gulp.src("src/package.json").pipe(gulp.dest("build"));
 });

 gulp.task("compile_index", function () {
     gulp.src("src/index/index.js").pipe(webpack({
         output: {
             filename: "index/index.js"
         },
         module: {
             loaders: [
                 {
                     test: /\.js$/,
                     loader: 'babel', // 'babel-loader' is also a valid name to reference
                     query: {
                         presets: ['es2017']
                     }
                 }
             ],
         },
         externals: {
             electron: "require('electron')",
             path: "require('path')",
             fs: "require('fs')",
             url: "require('url')"
         }
     })).pipe(gulp.dest("build"));
 });

 gulp.task("copy_main_js", function () {
     gulp.src("src/main.js").pipe(gulp.dest("build"));
 });

 gulp.task("default", ["copy_package_json", "copy_html_files", "copy_main_js", "compile_index"]);

4.根目录下的package.json配置好后：

 {
   "name": "application-name",
   "version": "0.0.1",
   "devDependencies": {
     "babel-core": "^6.18.2",
     "babel-loader": "^6.2.7",
     "babel-preset-es2017": "^6.16.0",
     "gulp": "^3.9.1",
     "gulp-webpack": "^1.5.0"
   }
 }

5.src 目录下的package.json是为了适应 electeon 的配置：

 {
   "scripts": {
     "start":"electron ."
   },
   "name": "application-name",
   "version": "0.0.1",
   "main": "main.js"
 }

6.src目录下的 main.js 文件也是为了适应 electron 的配置：

 /**
  * Created by Administrator on 2016/11/16.
  */

 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 win;

 function createWindow() {
     // Create the browser window.
     win = new BrowserWindow({width: 800, height: 600})

     var filepath = path.join(__dirname, 'index.html');

     console.log(filepath);

     // and load the index.html of the app.
     //此处需要手动配置   index.html 的路径
     win.loadURL(url.format({
         pathname: path.join(__dirname, "index", 'index.html'),
         protocol: 'file:',
         slashes: true
     }));

     // Open the DevTools.
     win.webContents.openDevTools();

     // Emitted when the window is closed.
     win.on('closed', () => {
         // 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.
         win = 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', () => {
     // 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', () => {
     // 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 (win === null) {
     createWindow()
 }
 });

7.src目录中的index中的   index.html  引入的是  index.js文件

8.配置时，将工程配置为   npm   :
