在新版本的 angular2 CLI https://cli.angular.io/ 添加库很简单.

In new version of angular2 CLI https://cli.angular.io/ it is simple to add library.

如果你只想添加 sockjs_client

If you want to add only sockjs_client

1) npm i --save sockjs-client

2) 在 typings.d.ts 中添加这个声明 declare module 'sockjs-client';

2) In typings.d.ts add this declaration declare module 'sockjs-client';

但我建议为 angular 2 使用 STOMP-Over-WebSocket 服务

But I would recommend to use STOMP-Over-WebSocket Service for angular 2

安装这个 npm 包

npm i --save stompjs
npm i --save sockjs-client
npm i --save ng2-stomp-service

在typings.d.ts

添加stompjs和sockjs-client模块声明

declare module 'stompjs';
declare module 'sockjs-client';

在app.module.ts

import { StompService } from 'ng2-stomp-service';

@NgModule({
  ...
  providers: [StompService]
})

在app.components.ts

import { StompService } from 'ng2-stomp-service';

private wsConf = {
  host:'test.com'
}

constructor(stomp: StompService) {

  stomp.configure(this.wsConf);

  stomp.startConnect().then(() => {
    console.log('connected');
  });


}
