Forward one (emitter|stream)'s events to another
(emitter|stream)'s events to another -> connect parts of your application whose interface you have no control over.
This is compatible both with the node-core EventEmitter and with component/emitter.
$ component install juliangruber/fwd$ npm install fwd
var fwd = ;var Stream = ;var EventEmitter = EventEmitter;// or: var EventEmitter = require('emitter')var src = ;var dest = ;;dest;src;
var src = ;srcreadable = true;var dest = ;;
var src = ;var dest = ;destwritable = true;;;
var src = ;srcreadable = true;var dest = ;destwritable = true;;
You can rewrite data on-the-fly:
var src = ;var dest = ;; // the same as with no 3rd argument// only forward event1 and event2// forward event1 as entry and everything else;;;
Forward all events from
Rewrite names and fwd only that.
mapping can be in an array to do multiple rewrites at one.
(data)and return modified
(event, data)and return
fn can also appear inside mappings.
stop is returned by every
fwd-call, so you can stop forwarding. Use this as stream-unpipe which isn't in the stream class yet.
$ git clone && cd fwd$ npm install$ mocha
