新项目使用 ng new [appname] --style less
已有的项目 修改 *.css 文件及引用处后缀名为 less并在 angular.json 文件中设置schematics为
"schematics": { "@schematics/angular:component": { "styleext": "less" } }
angular中的异步路由是模块级别的。
ng中一个组件只能属于一个模块，如果有一些公用的组件，虽然在app.module中全局注册可以，但是如果公用组件太多会导致app.module打包出来体积太大，所以我们可以使用共享组件。定义一个module，声明并抛出所有公用组件，然后当一个组件中想用共享组件的时候，直接在当前组件所属的module中import共享module就可以。
