event-debug

Log all events emitted by a Node.js EventEmitter object.

Installation

npm install event-debug

Usage

Example HTTP server where we log all event emitted by the server:

var http = require('http')
var eventDebug = require('event-debug')
 
var server = http.createServer(function (req, res) {
  console.log('-- Received request')
 
  eventDebug(req) // 1st argument should behave like an EventEmitter
  eventDebug(res)
 
  res.end('Hello World')
})
 
eventDebug(server, 'MyServer') // use custom logging prefix 'MyServer'
 
server.listen(3000, function () {
  console.log('-- Server is running on port 3000')
})

When running this server and sending an HTTP request to it, the following output will be produced (the lines written by event-debug are all written to STDERR):
