Webpack 是一个模块打包器。
它将根据模块的依赖关系进行静态分析，然后将这些模块按照指定的规则生成对应的静态资源。

基本命令

  webpack         // 最基本的启动webpack的方法  
  webpack -w      // 提供watch方法；实时进行打包更新
  webpack -p      // 对打包后的文件进行压缩
  webpack -d      // 提供source map，方便调式代码

全局安装

  # npm install webpack -g
  项目安装：
  # 进入项目目录
  # 确定已经有 package.json，没有就通过 npm init 创建
  # 安装 webpack 依赖
  # npm install webpack --save-dev

使用ES6

安装 babel-loader： 
# npm install babel-loader --save-dev
安装转码规则：       
# npm install babel-preset-es2015 --save-dev
ES7不同阶段语法提案的转码规则（共有4个阶段），选装一个
# npm install --save-dev babel-preset-stage-0
# npm install --save-dev babel-preset-stage-1
# npm install --save-dev babel-preset-stage-2
# npm install --save-dev babel-preset-stage-3
参考格式：
{
	test: /\.js$/,
	loader: 'babel?presets[]=es2015,presets[]=stage-0'
}

编译css

安装css-loader：  
# npm install css-loader  --save-dev
安装style-loader  
# npm install style-loader  --save-dev
参考格式：
{
	test: /\.css$/,
	loaders: ['style', 'css', 'autoprefixer']
}

编译less

# npm install less --save-dev
安装less-loader： 
# npm install less-loader --save-dev
参考格式：
{
	test: /\.less/,
	loaders: ['style', 'css', 'autoprefixer', 'less'],
}

使用autoprefixer自动补上浏览器兼容

# npm install autoprefixer-loader --save-dev
参考格式：
{
	test: /\.css$/,
	loaders: ['style', 'css', 'autoprefixer']
}, {
	test: /\.less/,
	loaders: ['style', 'css', 'autoprefixer', 'less'],
}

编译文件

安装file-loader： 
# npm install file-loader --save-dev
参考格式：
{
	test: /\.(eot|woff|svg|ttf|woff2|gif)(\?|$)/,
	loader: 'file-loader?name=[hash].[ext]'
}

编译图片

  # npm install url-loader --save-dev
  参考格式：
  {
  test: /\.(png|jpg)$/,
  loader: 'url?limit=1200&name=[hash].[ext]'
  }

编译JSX

  # npm install jsx-loader --save-dev
  # npm install babel-preset-react --save-dev
  参考格式：
  {
  test: /\.jsx$/,
  loaders: ['jsx', 'babel?presets[]=es2015,presets[]=stage-0,presets[]=react']
  }

示例源码

在项目目录下，新建一个webpack.config.js文件，把下面代码复制进去，然后在新建一个app.js和index.js文件，写上console.log('你好世界'); 执行命令：webpack 然后找到build目录就看到编译后的文件了

  var webpack = require('webpack');
  
  module.exports = {
	  entry: {
		  app: './app', //编译的入口文件
		  index: './index', //编译的入口文件
	  },
	  output: {
		  publicPath: '/build/', //服务器根路径
		  path: './build', //编译到当前目录
		  filename: '[name].js' //编译后的文件名字
	  },
	  module: {
		  loaders: [{
				  test: /\.js$/,
				  loader: 'babel?presets=es2015'
			  }, {
				  test: /\.css$/,
				  loaders: ['style', 'css', 'autoprefixer']
			  }, {
				  test: /\.less/,
				  loaders: ['style', 'css', 'autoprefixer', 'less'],
			  }, {
				  test: /\.(eot|woff|svg|ttf|woff2|gif)(\?|$)/,
				  loader: 'file-loader?name=[hash].[ext]'
			  }, {
				  test: /\.(png|jpg)$/,
				  loader: 'url?limit=1200&name=[hash].[ext]' //注意后面那个limit的参数，当你图片大小小于这个限制的时候，会自动启用base64编码图片
			  }
		  ]
	  },
	  plugins: [//plugins
			  new webpack.optimize.CommonsChunkPlugin('common.js'), //将公用模块，打包进common.js
			  new webpack.BannerPlugin('This file is created by viviannow')//插件的作用是给输出的文件头部添加注释信息。
	  ],
	  resolve: {
		  extensions: ['', '.js', '.jsx'] //后缀名自动补全
	  }
  };

This repo is a collection of simple demos of Webpack. 这个仓库是一些简单的webpack的例子的集合。

These demos are purposely written in a simple and clear style. You will find no difficulty in following them to learn the powerful tool.这些例子书写的都很简洁，你学起这个工具来不会有难度。

How to use 如何使用

First, install Webpack and webpack-dev-server globally.首先，你要全局的安装 webpack与webpack-dev-server。

//i =>install
$ npm i -g webpack webpack-dev-server

Then, clone the repo and install the dependencies. 然后，克隆仓库并安装依赖

$ git clone git@github.com:ruanyf/webpack-demos.git
$ cd webpack-demos
//下面是根据package.json安装
$ npm install

Now, play with the source files under the repo's demo* directories. 现在就可以运行demo...目录下的源文件了。

$ cd demo01
//下面是根据webpack.config.js的配制运行的。启动一个本地服务 
$ webpack-dev-server

Foreword: What is Webpack 前言：什么是webpack

Webpack is a front-end build systems like Grunt and Gulp. webpack是一个类似于grunt与gulp的前端构建工具

It can be used as a module bundler similar to Browserify, and do much more. 它可以像Browserify一样打包模块。并且可以做更多。

$ browserify main.js > bundle.js
# be equivalent to 等同于
$ webpack main.js bundle.js

Its configuration file is webpack.config.js. 它的配制文件是webpack.config.js

// webpack.config.js
module.exports = {
  entry: './main.js',
  output: {
    filename: 'bundle.js'
  }
};

After having webpack.config.js, you can invoke Webpack without any arguments.有了webpack.config.js文件你就可以不跟参数启用webpack。

$ webpack

Some command-line options you should know. 一些你要知道的命令行工具

webpack – for building once for development 在开发时构建一次
webpack -p – for building once for production (minification)再生产环境中构建 (minification微小)
webpack --watch – for continuous incremental build 监听文件改动，持续构建
webpack -d – to include source maps 引用源码的映射
webpack --colors – for making things pretty 优化输出

To produce a production ready application, you could write scripts field in your package.json file as following. 创建要投入生产的应用，你可以在package.json文件中添加 scripts字段，如下：

// package.json
{
  // ...
  "scripts": {
    "dev": "webpack-dev-server --devtool eval --progress --colors",
    "deploy": "NODE_ENV=production webpack -p"
  },
  // ...
}

Demo01: Entry file (source) 入口文件

Entry file is a file which Webpack will read to build bundle.js. webpack读取入口文件并编译成bundle.js

For example, main.js is an entry file. 例如，main.js是一个入口文件。

// main.js
document.write('<h1>Hello World</h1>');

index.html

<html>
  <body>
    <script type="text/javascript" src="bundle.js"></script>
  </body>
</html>

Webpack follows webpack.config.js to build bundle.js. webpack根据webpack.config.js去构建bundle.js

// webpack.config.js
module.exports = {
  entry: './main.js',
  output: {
    filename: 'bundle.js'
  }
};

Launch the server, visit http://127.0.0.1:8080 . 启动服务器，访问网址...

$ webpack-dev-server

Demo02: Multiple entry files (source)

Multiple entry files are allowed. It is useful for a multi-page app. 多入口文件是支持的，这对多入口应用来说很有用。

// main1.js
document.write('<h1>Hello World</h1>');

// main2.js
document.write('<h2>Hello Webpack</h2>');

index.html

<html>
  <body>
    <script src="bundle1.js"></script>
    <script src="bundle2.js"></script>
  </body>
</html>

webpack.config.js

module.exports = {
  entry: {
    bundle1: './main1.js',
    bundle2: './main2.js'
  },
  output: {
    filename: '[name].js'
  }
};

Demo03: Babel-loader (source) babel加载器

Loaders are preprocessors which transform a resource file of your app (more info). For example, Babel-loader can transform JSX/ES6 file into JS file. Official doc has a complete list of loaders. loaders是一个可以转换你应用源文件的预处理器，如Babel-loader可以把你的JSX/ES6文件转换成js文件，官方有完整的loaders的列表

main.jsx is a JSX file.

const React = require('react');
const ReactDOM = require('react-dom');

ReactDOM.render(
  <h1>Hello, world!</h1>,
  document.querySelector('#wrapper')
);

index.html

<html>
  <body>
    <div id="wrapper"></div>
    <script src="bundle.js"></script>
  </body>
</html>

webpack.config.js

module.exports = {
  entry: './main.jsx',
  output: {
    filename: 'bundle.js'
  },
  module: {
    loaders:[
      {
        // 加载babel-loader ，处理js或者jsx结尾的文件
        test: /\.js[x]?$/,
        exclude: /node_modules/,
        loader: 'babel-loader?presets[]=es2015&presets[]=react'
      },
    ]
  }
};

In webpack.config.js, module.loaders field is used to assign loaders. The above snippet uses babel-loader which also needs plugins babel-preset-es2015 and babel-preset-react to transpile ES6 and React. You can also take another way to set the babel query option. 在 webpack.config.js中，module.loaders是用来引用loaders的。上面用babel-loadder的同样要用插件babel-preset-es2015，与babel-preset-react去转义ES6与

module: {
  loaders: [
    {
      test: /\.jsx?$/,
      exclude: /node_modules/,
      loader: 'babel',
      query: {
        presets: ['es2015', 'react']
      }
    }
  ]
}

Demo04: CSS-loader (source)

Webpack allows you to require CSS in JS file, then preprocessed CSS file with CSS-loader.

main.js

require('./app.css');

app.css

body {
  background-color: blue;
}

index.html

<html>
  <head>
    <script type="text/javascript" src="bundle.js"></script>
  </head>
  <body>
    <h1>Hello World</h1>
  </body>
</html>

webpack.config.js

module.exports = {
  entry: './main.js',
  output: {
    filename: 'bundle.js'
  },
  module: {
    loaders:[
      { test: /\.css$/, loader: 'style-loader!css-loader' },
    ]
  }
};

Attention, you have to use two loaders to transform CSS file. First is CSS-loader to read CSS file, and another is Style-loader to insert Style tag into HTML page. Different loaders are linked by exclamation mark(!). 注意，你得用

After launching the server, index.html will have internal style sheet.

<head>
  <script type="text/javascript" src="bundle.js"></script>
  <style type="text/css">
    body {
      background-color: blue;
    }
  </style>
</head>

Demo05: Image loader (source)

Webpack could also require images in JS files.

main.js

var img1 = document.createElement("img");
img1.src = require("./small.png");
document.body.appendChild(img1);

var img2 = document.createElement("img");
img2.src = require("./big.png");
document.body.appendChild(img2);

index.html

<html>
  <body>
    <script type="text/javascript" src="bundle.js"></script>
  </body>
</html>

webpack.config.js

module.exports = {
  entry: './main.js',
  output: {
    filename: 'bundle.js'
  },
  module: {
    loaders:[
      { test: /\.(png|jpg)$/, loader: 'url-loader?limit=8192' }
    ]
  }
};

url-loader transforms image files. If the image size is smaller than 8192 bytes, it will be transformed into Data URL; otherwise, it will be transformed into normal URL. As you see, question mark(?) is be used to pass parameters into loaders.

After launching the server, small.png and big.png will have the following URLs.

<img src="data:image/png;base64,iVBOR...uQmCC">
<img src="4853ca667a2b8b8844eb2693ac1b2578.png">

Demo06: CSS Module (source)

css-loader?modules (the query parameter modules) enables the CSS Modules spec.

It means your module's CSS is local scoped CSS by default. You can switch it off with :global(...) for selectors and/or rules. (more info)

index.html

<html>
<body>
  <h1 class="h1">Hello World</h1>
  <h2 class="h2">Hello Webpack</h2>
  <div id="example"></div>
  <script src="./bundle.js"></script>
</body>
</html>

app.css

.h1 {
  color:red;
}

:global(.h2) {
  color: blue;
}

main.jsx

var React = require('react');
var ReactDOM = require('react-dom');
var style = require('./app.css');

ReactDOM.render(
  <div>
    <h1 className={style.h1}>Hello World</h1>
    <h2 className="h2">Hello Webpack</h2>
  </div>,
  document.getElementById('example')
);

webpack.config.js

module.exports = {
  entry: './main.jsx',
  output: {
    filename: 'bundle.js'
  },
  module: {
    loaders:[
      {
        test: /\.js[x]?$/,
        exclude: /node_modules/,
        loader: 'babel-loader',
        query: {
          presets: ['es2015', 'react']
        }
      },
      {
        test: /\.css$/,
        loader: 'style-loader!css-loader?modules'
      }
    ]
  }
};

Launch the server.

$ webpack-dev-server

Visit http://127.0.0.1:8080 , you'll find that only second h1 is red, because its CSS is local scoped, and both h2 is blue, because its CSS is global scoped.

Demo07: UglifyJs Plugin (source)

Webpack has a plugin system to expand its functions. For example, UglifyJs Plugin will minify output(bundle.js) JS codes.

main.js

var longVariableName = 'Hello';
longVariableName += ' World';
document.write('<h1>' + longVariableName + '</h1>');

index.html

<html>
<body>
  <script src="bundle.js"></script>
</body>
</html>

webpack.config.js

var webpack = require('webpack');
var uglifyJsPlugin = webpack.optimize.UglifyJsPlugin;
module.exports = {
  entry: './main.js',
  output: {
    filename: 'bundle.js'
  },
  plugins: [
    new uglifyJsPlugin({
      compress: {
        warnings: false
      }
    })
  ]
};

After launching the server, main.js will be minified into following.

var o="Hello";o+=" World",document.write("<h1>"+o+"</h1>")

Demo08: HTML Webpack Plugin and Open Browser Webpack Plugin (source)

This demo shows you how to load 3rd-party plugins.

html-webpack-plugin could create index.html for you, and open-browser-webpack-plugin could open a new browser tab when Webpack loads.

main.js

document.write('<h1>Hello World</h1>');

webpack.config.js

var HtmlwebpackPlugin = require('html-webpack-plugin');
var OpenBrowserPlugin = require('open-browser-webpack-plugin');

module.exports = {
  entry: './main.js',
  output: {
    filename: 'bundle.js'
  },
  plugins: [
    new HtmlwebpackPlugin({
      title: 'Webpack-demos',
      filename: 'index.html'
    }),
    new OpenBrowserPlugin({
      url: 'http://localhost:8080'
    })
  ]
};

Run webpack-dev-server.

$ webpack-dev-server

Now you don't need to write index.html by hand and don't have to open browser by yourself. Webpack did all these things for you.

Demo09: Environment flags (source)

You can enable some codes only in development environment with environment flags.

main.js

document.write('<h1>Hello World</h1>');

if (__DEV__) {
  document.write(new Date());
}

index.html

<html>
<body>
  <script src="bundle.js"></script>
</body>
</html>

webpack.config.js

var webpack = require('webpack');

var devFlagPlugin = new webpack.DefinePlugin({
  __DEV__: JSON.stringify(JSON.parse(process.env.DEBUG || 'false'))
});

module.exports = {
  entry: './main.js',
  output: {
    filename: 'bundle.js'
  },
  plugins: [devFlagPlugin]
};

Now pass environment variable into webpack.

# Linux & Mac
$ env DEBUG=true webpack-dev-server

# Windows
$ set DEBUG=true
$ webpack-dev-server

Demo10: Code splitting (source)

For big web apps it’s not efficient to put all code into a single file, Webpack allows you to split them into several chunks. Especially if some blocks of code are only required under some circumstances, these chunks could be loaded on demand.

At first, you use require.ensure to define a split point. (official document)

// main.js
require.ensure(['./a'], function(require) {
  var content = require('./a');
  document.open();
  document.write('<h1>' + content + '</h1>');
  document.close();
});

require.ensure tells Webpack that ./a.js should be separated from bundle.js and built into a single chunk file.

// a.js
module.exports = 'Hello World';

Now Webpack takes care of the dependencies, output files and runtime stuff. You don't have to put any redundancy into your index.html and webpack.config.js.

<html>
  <body>
    <script src="bundle.js"></script>
  </body>
</html>

webpack.config.js

module.exports = {
  entry: './main.js',
  output: {
    filename: 'bundle.js'
  }
};

Launch the server.

$ webpack-dev-server

On the surface, you won't feel any differences. However, Webpack actually builds main.js and a.js into different chunks(bundle.js and 1.bundle.js), and loads 1.bundle.js from bundle.js when on demand.

Demo11: Code splitting with bundle-loader (source)

Another way of code splitting is using bundle-loader.

// main.js

// Now a.js is requested, it will be bundled into another file
var load = require('bundle-loader!./a.js');

// To wait until a.js is available (and get the exports)
//  you need to async wait for it.
load(function(file) {
  document.open();
  document.write('<h1>' + file + '</h1>');
  document.close();
});

require('bundle-loader!./a.js') tells Webpack to load a.js from another chunk.

Now Webpack will build main.js into bundle.js, and a.js into 1.bundle.js.

Demo12: Common chunk (source)

When multi scripts have common chunks, you can extract the common part into a separate file with CommonsChunkPlugin.

// main1.jsx
var React = require('react');
var ReactDOM = require('react-dom');

ReactDOM.render(
  <h1>Hello World</h1>,
  document.getElementById('a')
);

// main2.jsx
var React = require('react');
var ReactDOM = require('react-dom');

ReactDOM.render(
  <h2>Hello Webpack</h2>,
  document.getElementById('b')
);

index.html

<html>
  <body>
    <div id="a"></div>
    <div id="b"></div>
    <script src="init.js"></script>
    <script src="bundle1.js"></script>
    <script src="bundle2.js"></script>
  </body>
</html>

webpack.config.js

var CommonsChunkPlugin = require("webpack/lib/optimize/CommonsChunkPlugin");
module.exports = {
  entry: {
    bundle1: './main1.jsx',
    bundle2: './main2.jsx'
  },
  output: {
    filename: '[name].js'
  },
  module: {
    loaders:[
      {
        test: /\.js[x]?$/,
        exclude: /node_modules/,
        loader: 'babel-loader',
        query: {
          presets: ['es2015', 'react']
        }
      },
    ]
  },
  plugins: [
    new CommonsChunkPlugin('init.js')
  ]
}

Demo13: Vendor chunk (source)

You can also extract the vendor libraries from a script into a separate file with CommonsChunkPlugin.

main.js

var $ = require('jquery');
$('h1').text('Hello World');

index.html

<html>
  <body>
    <h1></h1>
    <script src="vendor.js"></script>
    <script src="bundle.js"></script>
  </body>
</html>

webpack.config.js

var webpack = require('webpack');

module.exports = {
  entry: {
    app: './main.js',
    vendor: ['jquery'],
  },
  output: {
    filename: 'bundle.js'
  },
  plugins: [
    new webpack.optimize.CommonsChunkPlugin(/* chunkName= */'vendor', /* filename= */'vendor.js')
  ]
};

If you want a module available as variable in every module, such as making $ and jQuery available in every module without writing require("jquery"). You should use ProvidePlugin (Official doc).

// main.js
$('h1').text('Hello World');


// webpack.config.js
var webpack = require('webpack');

module.exports = {
  entry: {
    app: './main.js'
  },
  output: {
    filename: 'bundle.js'
  },
  plugins: [
    new webpack.ProvidePlugin({
      $: "jquery",
      jQuery: "jquery",
      "window.jQuery": "jquery"
    })
  ]
};

Demo14: Exposing global variables (source)

If you want to use some global variables, and don't want to include them in the Webpack bundle, you can enable externals field in webpack.config.js (official document).

For example, we have a data.js.

var data = 'Hello World';

We can expose data as a global variable.

// webpack.config.js
module.exports = {
  entry: './main.jsx',
  output: {
    filename: 'bundle.js'
  },
  module: {
    loaders:[
      {
        test: /\.js[x]?$/,
        exclude: /node_modules/,
        loader: 'babel-loader',
        query: {
          presets: ['es2015', 'react']
        }
      },
    ]
  },
  externals: {
    // require('data') is external and available
    //  on the global var data
    'data': 'data'
  }
};

Now, you require data as a module variable in your script. but it actually is a global variable.

// main.jsx
var data = require('data');
var React = require('react');
var ReactDOM = require('react-dom');

ReactDOM.render(
  <h1>{data}</h1>,
  document.body
);

Demo15: Hot Module Replacement (source)

Hot Module Replacement (HMR) exchanges, adds, or removes modules while an application is running without a page reload.

You have two ways to enable Hot Module Replacement with the webpack-dev-server.

(1) Specify --hot and --inline on the command line

$ webpack-dev-server --hot --inline

Meaning of the options:

--hot: adds the HotModuleReplacementPlugin and switch the server to hot mode.
--inline: embed the webpack-dev-server runtime into the bundle.
--hot --inline: also adds the webpack/hot/dev-server entry.

(2) Modify webpack.config.js.

add new webpack.HotModuleReplacementPlugin() to the plugins field
add webpack/hot/dev-server and webpack-dev-server/client?http://localhost:8080 to the entry field

webpack.config.js looks like the following.

var webpack = require('webpack');
var path = require('path');

module.exports = {
  entry: [
    'webpack/hot/dev-server',
    'webpack-dev-server/client?http://localhost:8080',
    './index.js'
  ],
  output: {
    filename: 'bundle.js',
    publicPath: '/static/'
  },
  plugins: [
    new webpack.HotModuleReplacementPlugin()
  ],
  module: {
    loaders: [{
      test: /\.jsx?$/,
      exclude: /node_modules/,
      loader: 'babel-loader',
      query: {
        presets: ['es2015', 'react']
      },
      include: path.join(__dirname, '.')
    }]
  }
};

Now launch the dev server.

$ webpack-dev-server

Visiting http://localhost:8080, you should see 'Hello World' in your browser.

Don't close the server. Open a new terminal to edit App.js, and modify 'Hello World' into 'Hello Webpack'. Save it, and see what happened in the browser.

App.js

import React, { Component } from 'react';

export default class App extends Component {
  render() {
    return (
      <h1>Hello World</h1>
    );
  }
}

index.js

import React from 'react';
import ReactDOM = require('react-dom');
import App from './App';

ReactDOM.render(<App />, document.getElementById('root'));

index.html

<html>
  <body>
    <div id='root'></div>
    <script src="/static/bundle.js"></script>
  </body>
</html>
