Rx.Observable.never()

Ⓢ

Returns a non-terminating observable sequence, which can be used to denote an infinite duration (e.g. when using reactive joins).

Returns

(Observable): An observable sequence whose observers will never get called.

Example

// This will never produce a value, hence never calling any of the callbacks
var source = Rx.Observable.never();

var subscription = source.subscribe(
    function (x) {
        console.log('Next: ' + x);
    },
    function (err) {
        console.log('Error: ' + err);
    },
    function () {
        console.log('Completed');
    });
