`ConnectableObservable.prototype.connect()`

# Ⓢ

Connects the observable wrapper to its source. All subscribed observers will receive values from the underlying observable sequence as long as the connection is established.

Returns

(Disposable): Disposable object used to disconnect the observable wrapper from its source, causing subscribed observer to stop receiving values from the underlying observable sequence.

Example

var interval = Rx.Observable.interval(1000);

var source = interval
    .take(2)
    .do(function (x) {
        console.log('Side effect');
    });

var published = source.publish();

published.subscribe(createObserver('SourceA'));
published.subscribe(createObserver('SourceB'));

// Connect the source
var connection = published.connect();

function createObserver(tag) {
    return Rx.Observer.create(
        function (x) {
            console.log('Next: ' + tag + x);
        },
        function (err) {
            console.log('Error: ' + err);
        },
        function () {
            console.log('Completed');
        });
}
