问题描述
这两个模块的目的是什么?
What are the purposes of these two modules?
import { BrowserModule } from '@angular/platform-browser';
import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
推荐答案
platformBrowserDynamic是用于引导Angular应用程序的函数.
platformBrowserDynamic is a function used to bootstrap an Angular application.
CommonModule是一个模块，提供通常在Angular2应用程序(如ngIf)中使用的各种服务和指令. CommonModule与平台无关.
CommonModule is a module that provides all kinds of services and directives one usually wants to use in an Angular2 application like ngIf. CommonModule is platform-independent.
BrowserModule导出CommonModule并提供一些特定于浏览器平台的服务(与ServerModule或ServiceWorkerModule相反).
BrowserModule exports CommonModule and provides a few services specific to the browser platform (in contrary to ServerModule or ServiceWorkerModule).
BrowserModule仅应在AppModule中导入，CommonModule可以在任何地方导入.
BrowserModule should only be imported in AppModule, CommonModule can be imported everywhere.
