Very differently to AngularJS (v1.x), Angular now has a hierarchical dependency injector. That allows to specify service definitions as well as the service lifetime at various levels in our application. Whenever a service is requested, Angular will w…

前言 因工作繁忙,差不多有三个月没有写过技术文章了,自八月份第一次编写 schematics 以来,我一直打算分享关于 schematics 的编写技巧,无奈还是拖到了年底. Angular Schematics 是非常强大的一个功能,可以快速初始化项目,也可以自定义组件模板.在去年 schematics 发布以来,已经有部分开发者在项目中尝试使用,但是学习资料还是比较匮乏.目前官网已经有了 schematics 的简易教程,但在实际开发中仅靠官方教程还是会遇到很多问题.在开发 Ng-Mater…

在angular的服务中,有一些服务你不得不去了解,因为他可以说是ng的核心,而今天,我要介绍的就是ng的两个核心服务,$parse和$compile.其实这两个服务讲的人已经很多了,但是100个读者就有100个哈姆雷特,我在这里讲讲自己对于他们两个服务的理解. 大家可能会疑问,$eval呢,其实他并不是一个服务,他是scope里面的一个方法,并不能算服务,而且它也基于parse的,所以只能算是$parse的另一种写法而已,我们看一下ng源码中$eval的定义是怎样的就知道了 $eval: fu…
