Transform the subscription into a string

When I use the http method to retrieve a single user, the output logged in the console looks like this: this.usersService.getOneUser().subscribe(data => { console.log(data) });

email: "<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="31444254430371565c50585d1f525e5c">[email protected]</a>"
id: "1"
phoneNumber: "23421234"
userName: "user2"

Now, I need to store these values in a new array object. My attempt is shown below:

    this.users = new Array(1).fill({}).map((_, index) => {
      return <User>{

        userName: this.usersService.getOneUser().subscribe(data => {JSON.stringify(data.userName)})

      };
    });

I tried converting to JSON format without success. Manually typing in values works for adding a user, but the issue lies in populating it from the data obtained through the http request.

      return <User>{

        email: '<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="b4c0d1c7c0f4d9d5ddd89ad7dbd9">[email protected]</a>',
        id: '1',
        phoneNumber: '12345',
        userName: 'user'
      };
    });

The compiler returns an error stating "userName: Subscription neither type sufficiently overlaps with the other"

Answer №1

this.userService
  .fetchUser()
  .subscribe(response => this.userList = [response]);

That should get the job done.

Answer №2

const userArray = new Array(1).fill({}).map((_, index) => {
      return {
        userName: this.usersService.getOneUser().subscribe(data => {JSON.stringify(data.userName)})
      };
    });

It is possible that the call to getOneUser() may not have completed before the execution of Array.fill(..) due to its asynchronous nature.
