概述 Angular2官方推荐的应该是使用systemjs加载, 但是当我使用到它的tree shaking的时候,发现如果使用systemjs+rollup,只能打包成一个文件,然后lazy loading就没法搞了. 因此我使用了webpack2,webpack2自带tree shaking,只要将tsconfig中的module设置成es2015就可以, 虽然效果没rollup好,但支持lazy loading. 另外, angular2目前不支持typescript 2.1.X,所以如果…

Introduction Lazy loading is a concept where we delay the loading of the object until the point where we need it. Putting in simple words, on demand object loading rather than loading objects unnecessarily. For example, consider the below example whe…
We've looked at lazy loading with ocLazyLoad previously, but what if we are using ui-router and want to lazy load modules when we change states? angular.module("demo", ["ui.router", "oc.lazyLoad"]) .config(function ($statePro…
With the ocLazyLoad you can load AngularJS modules on demand. This is very handy for runtime loading of Angular modules in large applications. Simple example: angular.module("demo", ["oc.lazyLoad"]) .controller("AppCtrl", fun…
Why bother lazy loading and purging pages, you ask? Well, in this example, it won't matter too much if you load all the pages at the start, since there are only five and they won't be large enough to eat up too much memory. But imagine you had 100 pa…
Entity Framework提供了三种加载相关实体的方法:Lazy Loading,Eager Loading和Explicit Loading.首先我们先来看一下MSDN对三种加载实体方法的定义. Lazy Loading:对于这种类型的加载,在您访问导航属性时,会从数据源自动加载相关实体. 使用此加载类型时,请注意,如果实体尚未在 ObjectContext 中,则您访问的每个导航属性都会导致针对数据源执行一个单独的查询. Eager Loading:当您了解应用程序需要的相关实体的图形…
EntityFramework Eagerly Loading Eager loading is the process whereby a query for one type of entity also loads related entities as part of the query. Eager loading is achieved by use of the Include method. For example, the queries below will load blo…
前言 本篇是上一篇EFCore Lazy Loading + Inheritance = 干净的数据表 (一) [献给处女座的DB First程序猿] 前菜 的续篇.这一篇才是真的为处女座的DB First程序猿准备的正餐. 继续上一篇的话题,我们希望用EFCore,且继续使用与逻辑设计的β角偏差很少的数据表结构,彻底不想看到那种"装饰墙"的效果. 提醒一下,这一部分,属于有点"走火入魔"的性质.因为是要回过头来改动类的代码(稍微改动逻辑设计)来迁就数据表(物理设计…
