Receiving contextual information from Microsoft Teams within an Angular application integrated as a tab

I am currently integrating an Angular website into a Microsoft Teams tab. In order to perform certain computations, I need to retrieve the Team ID. To achieve this, I have recently added

npm install --save @microsoft/teams-js
.

Below is the code snippet that I used:

import { Component } from "@angular/core";
import * as microsoftTeams from "@microsoft/teams-js";

@Component({
  selector: "app-root",
  templateUrl: "./app.component.html",
  styleUrls: ["./app.component.css"]
})
export class AppComponent {
  title = "app";
  teamID: string;
  teamName: string;
  groupID: string;
  
  ngOnInit() {
    microsoftTeams.initialize();

    microsoftTeams.getContext(function(Context: microsoftTeams.Context) {
      alert("getcontext call back function");
      this.teamName = Context.teamName;
      this.groupID = Context.groupId;
      this.teamID = Context.teamId;
    });

    alert("after get context");
    console.log("End");
  }
}

The issue I am facing is that I am unable to fetch the microsoftTeams.Context. Is there any additional step that needs to be taken? How should I tackle this problem correctly?

Answer №1

When using context as a callback in microsoftTeams.getContext, it's important to remember to include .bind(this) after the function. Here is an example:

microsoftTeams.getContext(function(Context: microsoftTeams.Context) {
    alert("getcontext call back function");
    this.teamName = Context.teamName;
    this.groupID = Context.groupId;
    this.teamID = Context.teamId;
}).bind(this));
