Incoming information obtained via Websocket

Currently, I am working with Angular and attempting to retrieve data from the server using websockets. Despite successfully receiving the data from the server, I am faced with a challenge where instead of waiting for the server to send the data, it returns null. For instance:

this.wsService.createObservableSocket(environment.webSocketUrl).subscribe(data=>{
   console.log("data received !");
   this.messageFromServer = data;
});

//This scenario occurs prior to receiving the data from the server.
// How can I ensure that this only happens after receiving data from the server or
// whenever data is received from the server

this.DoSomething(this.messageFromServer);

Answer №1

Execute the function DoSomething() once the data has been successfully received.

Consider implementing it in this manner:

this.myWebSocketService.createObservableSocket(environment.webSocketUrl).subscribe(data=>{
  console.log("Data has been received !");
  this.messageFromServer = data;
  this.DoSomething(this.messageFromServer);
});
