默认生成的有两份文件,ts 和 测试文件。 ng g class/interface/enum 创建实体类,接口,或枚举的命令,因为这些类型的文件,默认需要的代码模板并不多,即使不用命令创建,手动创建也行。 ng g module 创建一个模块,这个命令有几个比较常用的选项配置: --flat=true|false 当为true 时,在当前目录下创建指定的 xxx....

implementors of this interface are now required to provide an implementation for this method. This breakage is unlikely to affect application developers, as `AnimationDriver` is not expected to be implemented in user code. ### common - Adds new required class member that any implementors of the...

Components –Angular uses a component-based architecture, with each component translating into the user interface elements seen on a webpage. In code, each component corresponds to a class that defines its functionality and an HTML template that defines its view. By default, Angular applications hav...
