使用webpack导入angularjs的最佳做法是什么？-Java 学习之路

你如何一起使用Webpack和AngularJS，以及模板加载和按需提取资源如何？

为此目的编写良好的 webpack.config.js 文件的一个例子将非常感谢 .

此处显示的所有代码段都可以在this github repo访问 . 代码已经从this packetloop git repo慷慨改编 .

webpack.config.json

var path = require('path');
var ResolverPlugin = require("webpack/lib/ResolverPlugin");

var config = {
  context: __dirname,
  entry: ['webpack/hot/dev-server', './app/app.js'],
  output: {
    path: './build',
    filename: 'bundle.js'
  },
  module: {
    loaders: [{
      test: /\.css$/,
      loader: "style!css-loader"
    }, {
      test: /\.scss$/,
      loader: "style!css!sass?outputStyle=expanded"
    }, {
      test: /\.jpe?g$|\.gif$|\.png$|\.svg$|\.woff$|\.ttf$/,
      loader: "file"
    }, {
      test: /\.html$/,
      loader: "ngtemplate?relativeTo=" + path.join(__dirname, 'app/') + "!raw"
    }]
  },
  // Let webpack know where the module folders are for bower and node_modules
  // This lets you write things like - require('bower/<plugin>') anywhere in your code base
  resolve: {
    modulesDirectories: ['node_modules', 'lib/bower_components'],
    alias: {
      'npm': __dirname + '/node_modules',
      'vendor': __dirname + '/app/vendor/',
      'bower': __dirname + '/lib/bower_components'
    }
  },
  plugins: [
    // This is to help webpack know that it has to load the js file in bower.json#main
    new ResolverPlugin(
      new ResolverPlugin.DirectoryDescriptionFilePlugin("bower.json", ["main"])
    )
  ]
};

module.exports = config;

要将AngularJS导入主 app.js ，请执行以下操作：

app/vendor/angular.js

'use strict';

if (!global.window.angular) {
  require('bower/angular/angular');
}
var angular = global.window.angular;
module.exports = angular;

然后在_481518中使用它，就像这样，

app.js

...
var angular = require('vendor/angular');

// Declare app level module
var app = angular.module('myApp', []);

...

以下是否正确？有更简单的方法吗？我看过一些列出另一种方法的帖子（不是很多标准） .

从this reddit post comment

// Add to webpack.config.js#module#loaders array
    {
      test: /[\/]angular\.js$/,
      loader: "exports?angular"
    }

还有另一个插件正在开发中，现在正在stackfull/angular-seed . 它似乎是在正确的方向，但现在真的很难使用 .

Webpack非常棒，但缺少文档和样本正在扼杀它 .

您可以在需要的所有模块（文件）中要求角度 . 我有一个github repository示例如何做到这一点（也使用webpack进行构建） . 在示例中使用ES6导入语法，但无关紧要，您可以使用标准 require() .

例：

import 'bootstrap/dist/css/bootstrap.min.css';
import './app.css';

import bootstrap from 'bootstrap';

import angular from 'angular';
import uirouter from 'angular-ui-router';

import { routing} from './app.config';

import common from './common/common.module';

import featureA from './feature-a/feature-a.module';
import featureB from './feature-b/feature-b.module';

const app = angular
    .module('app', [uirouter, common, featureA, featureB])
    .config(routing);

我开始 Angular + Flux 与 Webpack 所以我可以帮助你做一些事情 .

基本上我用 NPM 安装所有东西，它有 module export 系统，所以它没有任何作用 . （您可以使用 export-loader ，但如果您不需要，可以使用 . ）

我的 webpack.config.js 看起来像这样：

var webpack           = require('webpack');
var path              = require('path');
var HtmlWebpackPlugin = require("html-webpack-plugin");

var nodeModulesDir = path.resolve(__dirname, './node_modules');

// Some of my dependencies that I want
// to skip from building in DEV environment
var deps = [
  'angular/angular.min.js',
  ...
];

var config = {
  context: path.resolve(__dirname, './app'),

  entry: ['webpack/hot/dev-server', './main.js'],

  resolve: {
    alias: {}
  },

  output: {
    path: path.resolve(__dirname, './build'),
    filename: 'bundle.js'
  },

  // This one I am using to define test dependencies
  // directly in the modules
  plugins: [
    new webpack.DefinePlugin({
      ON_TEST: process.env.NODE_ENV === 'test'
    })
  ],

  module: {
    preLoaders: [
      {test: /\.coffee$/, loader: "coffeelint", exclude: [nodeModulesDir]}
    ],
    loaders: [
      {test: /\.js$/, loader: 'ng-annotate', exclude: [nodeModulesDir]},
      {test: /\.coffee$/, loader: 'coffee', exclude: [nodeModulesDir]},
        ...
    ],
    noParse: []
  },

  devtool: 'source-map'
};

if (process.env.NODE_ENV === 'production') {
  config.entry = {
    app: path.resolve(__dirname, './app/main.js'),
     vendors: ['angular']
  };
  // config.output.path = path.resolve(__dirname, './dist');
 config.output = {
   path: path.resolve(__dirname, "./dist"),
  filename: "app.[hash].js",
  hash: true
 };
 config.plugins.push(new webpack.optimize.UglifyJsPlugin());
 config.plugins.push(new webpack.optimize.CommonsChunkPlugin('vendors', 'vendors.[hash].js'));
 config.plugins.push(new HtmlWebpackPlugin({
   title: 'myApp',
   template: path.resolve(__dirname, './app/index.html'),
   inject: 'body'
 }));

 delete config.devtool;


}
  else {
    deps.forEach(function (dep) {
      var depPath = path.resolve(nodeModulesDir, dep);
      config.resolve.alias[dep.split(path.sep)[0]] = depPath;
      config.module.noParse.push(depPath);
    });
  }
module.exports = config;

我的 main.js 看起来像这样：

var angular = require('angular');

if(ON_TEST) {
  require('angular-mocks/angular-mocks');
}

require('./index.coffee');

和 index.coffee 包含主角度模块：

ngModule = angular.module 'myApp', []

require('./directive/example.coffee')(ngModule)
