Javascript 在带有browserify的angular中延迟加载组件
我正在概述一个基于angular的相当复杂的应用程序的体系结构。所以我从angular seed项目开始,这似乎是一个很好的起点。让我烦恼的是,angular应用程序本质上涉及到预先加载所有内容。对于脚本加载程序,似乎没有一种干净的方法 我来自backbone.js的背景,在那里使用require.js进行基于路由器回调的延迟加载非常简单。在某些情况下,角度布线的定义如下所示:Javascript 在带有browserify的angular中延迟加载组件,javascript,angularjs,browserify,Javascript,Angularjs,Browserify,我正在概述一个基于angular的相当复杂的应用程序的体系结构。所以我从angular seed项目开始,这似乎是一个很好的起点。让我烦恼的是,angular应用程序本质上涉及到预先加载所有内容。对于脚本加载程序,似乎没有一种干净的方法 我来自backbone.js的背景,在那里使用require.js进行基于路由器回调的延迟加载非常简单。在某些情况下,角度布线的定义如下所示: // Declare app level module which depends on views, and com
// Declare app level module which depends on views, and components
angular.module('myApp', [
'ngRoute'
]).
config(['$routeProvider', function($routeProvider) {
$routeProvider.when({templateURL:'../tmpl.html',controller:'view1Ctrl'})
.when({templateURL:'../tmpl.html',controller:'view1Ctrl'})
.otherwise({redirectTo: '/view1'});
}]);
现在在这里,$routeProvider.when({templateURL:'../tmpl.html',controller:'view1Ctrl'})
我想延迟加载控制器和模板。我很想用这样的东西:
$routeProvider.when({templateURL:'../tmpl.html',controller:require('view1Ctrl'})
使用browserify,但它似乎不干净,甚至不符合要求。我知道这个问题已经被问了好几次了,但我还没有找到一个明确的答案
我的首选是使用browserify,因为它支持浏览器中备受喜爱的cjs模块。我不知道如何使用browserify实现这一点,因为我自己从未尝试过,但我强烈建议您仔细研究 作为一个独立的服务,它可以通过加载文件(json、css、js、模板——你可以随意命名)并将其注入到已经运行的angular应用程序中来实现奇迹般的效果 尽管如此,它与路由器(默认的角度路由器或ui路由器)结合使用(imo)效果更好 有一些“种子项目”展示了如何将ocLazyLoad与SystemJS结合使用
但你甚至不需要它。 如果使用ui router、ui router extras和ocLazyLoad,您可以将以下内容组合到延迟加载状态: main.js
/**
* Inject the needed dependencies into our main module.
*/
var main = angular.module('main', [ 'ui.router', 'ct.ui.router.extras.future', 'oc.lazyLoad' ]);
/**
* Define the lazy loaded states.
*/
main.constant('lazyLoadedStates', [
{
name: 'about',
url: '/about',
type: 'lazy',
src: [
'/path/to/about.module.js',
'/path/to/AboutController.js'
]
}
]);
/**
* Setup the behaviour for when we hit a futureState with the 'lazy'
* type.
*
* 1. Setup a deferred object.
* 2. Resolve the promise when every file defined in the futureState.src has been loaded.
* 3. Return the promise.
*/
main.config(function ($futureStateProvider, lazyLoadedStates) {
$futureStateProvider.stateFactory('lazy', function ($q, $ocLazyLoad, futureState) {
var deferred = $q.defer();
$ocLazyLoad.load(futureState.src).then(function () {
deferred.resolve();
});
return deferred.promise;
});
lazyLoadedStates.forEach($futureStateProvider.futureState);
});
/**
* Setup the _real_ '/about' state in this lazy loaded file.
*/
angular.module('about', []).config(function ($stateProvider) {
$stateProvider.state('about', {
url: '/about',
controller: 'AboutController',
template: 'some_template.html'
});
});
/**
* Register the AboutController in a lazy loaded file. This could be done in about.module.js aswell,
* but we'll do it here to separate stuff and showcase loading of multiple files.
*/
angular.module('about').controller('AboutController', function ($state) {
console.log('Im on a lazy loaded state!', $state.current);
});
这就是“框架”——现在您只需要不断添加更多模块和更多代码,并在
lazyLoadedStates
常量中将真实状态定义与虚拟状态定义相匹配
关于.module.js

我希望这能让您大致了解如何在Angular中设置延迟加载状态。我还没有找到一个更简单的方法来做到这一点,但我相信有一些文章是关于如何将ui路由器(或默认的角度路由器)与其他一些“惰性加载程序”耦合的 文档链接:
$controllerProvider.register
,$provide.factory
和$compileProvider.directive
在某些时候必须在运行状态下使用它们。但是,这是一种黑客行为(此外,我认为这与:
