I have a REST API, I want to send event to the client via websocket. How to inject websocket instance in controller or another component?

推荐答案

class Gateway 可以注入到另一个组件中，并使用服务器实例.

class Gateway can be injected in another component, and use the server instance.

@Controller()
export class AppController {
  constructor(
    private readonly appService: AppService,
    private readonly messageGateway: MessageGateway
  ) {}

  @Get()
  async getHello() {
    this.messageGateway.server.emit('messages', 'Hello from REST API');
    return this.appService.getHello();
  }
}
