Package Exports

propagate

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (propagate) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

propagate

Propagate events from one event emitter into another

Install

$ npm install propagate

Propagate

  var ee1 = new EventEmitter();
  var ee2 = new EventEmitter();
  propagate(ee1, ee2);

  ee2.on('event', function(a, b) {
    console.log('got propagated event', a, b);
  });

  ee1.emit('event', 'a', 'b');

Unpropagate

You can unpropagate by ending the propagation like this:

  var ee1 = new EventEmitter();
  var ee2 = new EventEmitter();
  var p = propagate(ee1, ee2);

  // ...

  p.end();

Only propagate certain events:

  var ee1 = new EventEmitter();
  var ee2 = new EventEmitter();
  var p = propagate(['event1', 'event2'], ee1, ee2);

Propagate certain events as other events:

  var ee1 = new EventEmitter();
  var ee2 = new EventEmitter();
  var p = propagate({
    'event1': 'other-event1',
    'event2': 'other-event2'
  }, ee1, ee2);
