    Forward-emitter

    Forward events from one Node EventEmitter to another.

    Installation

    npm install forward-emitter

    Usage

    var forward = require('forward-emitter');
     
    // Basic forwarding
    forward(src, dest);
     
    // Forward only selected events
    // In this example, only the 'connect' event is forwarded.
    forward(src, dest, function (eventName) {
      return eventName === 'connect';
    });
     
    // Forward all events except exclusions
    var exclusions = ['connect', 'disconnect'];
    forward(src, dest, function(eventName) {
      return exclusions.indexOf(eventName) === -1;
    });
     

    How It Works

    forward-emitter listens to the newListener and removeListener events, introduced in Node 0.8 and Node 0.10 respectively. When a callback is bound to an event on the destination emitter, the listener is forwarded to the source emitter.

    For that reason, this module should not be used in Node < 0.10 if you plan to use removeListener.

    Install

    npm i forward-emitter
