piper

Piper is small module that provides automatic namespacing helpers when working with eve.

Example Usage

var pipe = require('piper')('sample-ns');
 
pipe
.on('*', function() {
  console.log('event fired "' + pipe.nt() + '" which maps to eve event "' + pipe.eve.nt() + '"');
})
.on('load', function() {
  console.log('loaded');
})
.emit('load');
 

Example Usage: Bridge via Redis

In addition to namespacing helpers, piper also provides some transport helpers for directing messages via a network transport (such as redis pubsub):

var piper = require('piper');
var testpipe = piper('test');
 
// publish events via redis
var bridge = piper.bridge(require('piper/transports/redis')({
  host: 'localhost',
  channel: 'redis-test-channel'
}));
 
// start the bridge publishing
bridge.pub();
 
// fire an event
testpipe('hit', 'car');
 

This example would display something similar to the following if you were using the MONITOR command in the redis-cli:

1399858559.348511 [0 127.0.0.1:39324] "publish" "redis-test-channel" "[\"test.hit\",\"car\"]"
