AngularJS和Webpack集成 [英] AngularJS and Webpack Integration

问题描述

我正在寻找一些帮助，使用 webpack 获取大型AngularJS应用程序。我们正在使用基于功能的文件夹结构（每个功能/页面都有一个模块，它们有控制器，指令）。我已成功配置webpack以使其与Grunt一起工作，Grunt生成一个单独的捆绑包。我想创建一个块，因为它将成为一个大型应用程序，我们想异步加载模块（页面/功能）工件。

I am looking for some help with using webpack for a large AngularJS application. We are using folder structure based on feature (each feature/page has a module and they have controllers, directives). I have successfully configured webpack to get it working with Grunt, which produces one single bundle. I want to create chunks as its going to be a large app, we would like to load modules (page/feature) artifacts asynchronously.

我正在通过一些webpack示例使用'代码拆分'使用 require（[deps]，fn）语法。但是我无法让懒人装满块。首先，我不知道究竟在哪里，我需要在AngularJS将用户路由到下一页之前导入这些块。我正在努力寻找明确的责任分离。

I am going through some of the webpack example to use 'code splitting' using require([deps],fn ) syntax. However I couldn't get the chunks lazy-loaded. First of all, I don't know where exactly, I would need to import these chunks before AngularJS would route the user to next page. I am struggling to find a clear separation of responsibility.

是否有人向我指出一个示例AngularJS应用程序，其中webpack用于在每个路由后异步加载控制器/指令/过滤器？

Did someone point me to an example AngularJS application where webpack is used to load controllers/directives/filters asynchronously after each route?

推荐答案

Sagar Ganatra写了一个有用的<关于代码拆分的href =http://www.sagarganatra.com/2014/08/lazy-loading-angularjs-components-using-providers.html>博文。

Sagar Ganatra wrote a helpful blog post about code splitting.

令人惊讶的是，angular的模块系统并不支持代码拆分。但是，有一种方法可以通过在配置阶段保存对angular的特殊提供程序的引用来实现代码拆分。

Suprisingly code splitting isn't really supported by angular's module system. However, there is a way to achieve code splitting by saving a reference to angular's special providers during the config-phase.

[...当Angular初始化或引导应用程序，功能 - 控制器，服务等时。在模块实例上可用。在这里，我们延迟加载组件，稍后无法使用这些功能;因此，我们必须使用各种提供程序函数并注册这些组件。提供程序仅在config方法中可用，因此在初始化应用程序时，我们必须在config函数中存储这些提供程序的引用。

[...] when Angular initializes or bootstraps the application, functions - controller, service etc,. are available on the module instance. Here, we are lazy loading the components and the functions are not available at a later point; therefore we must use the various provider functions and register these components. The providers are available only in the config method and hence we will have to store a reference of these providers in the config function when the application is initialized.

window.app.config([
    '$routeProvider',
    '$controllerProvider',
    '$compileProvider',
    '$filterProvider',
    '$provide',
    function ($routeProvider, $controllerProvider, $compileProvider, $filterProvider, $provide) {

        $routeProvider.when('/login', {
            templateUrl: 'components/login/partials/login.html',
            resolve: {
                load: ['$q', '$rootScope', function ($q, $rootScope) {

                    var deferred = $q.defer();

                    // lazy load controllers, etc.
                    require ([
                        'components/login/controllers/loginController',
                        'components/login/services/loginService'
                    ], function () {

                        $rootScope.$apply(function () {
                            deferred.resolve();
                        });

                    });

                    return deferred.promise;
                }]
            }
        });


        //store a reference to various provider functions
        window.app.components = {
            controller: $controllerProvider.register,
            service: $provide.service
        };

    }
]);

现在在你的 loginController 里面你写的

app.components.controller('loginController');

懒洋洋地定义你的新控制器。

to define your new controller lazily.

如果您想延迟加载模板，我建议使用 ui-router 。在那里你可以指定一个 templateProvider 这是基本上是一个函数加载模板异步

If you want to lazy-load your templates too I recommend to use the ui-router. There you can specify a templateProvider which is basically a function to load templates async
