Emit a single value

rated 0 times [ 190] [ 7] / answers: 1 / hits: 28719 / 9 Years ago, wed, january 20, 2016, 12:00:00

I would like to emit a single value.

According to this post, the following should be valid:

var requestStream = Rx.Observable.just('https://api.github.com/users');

However, this does not work. just is not defined.

Has it been deprecated? Is there something that I can use instead?

A lot of the stuff is tucked away in: import 'rxjs/Rx'; You might try Observable.of for a single value.

This works for me (plunker):

import {Component} from 'angular2/core';

import {Observable} from 'rxjs/Observable';

import 'rxjs/Rx';



@Component({

  selector: 'my-app',

  providers: [],

  template: `

    <div>

      <h2>Hello {{test | async}}</h2>     

    </div>

  `,

  directives: []

})

export class App {

    test: Observable<any> = Observable.of(I'm an observable);

    constructor() {

  }

}
