Installation

$ npm install chromelogger

and install the Chrome Logger extension in your Chrome browser.

Usage

var chromelogger = require('chromelogger');
var http = require('http');

var server = http.createServer();

server.on('request', chromelogger.middleware);

server.on('request', function(req, res) {
  res.chrome.log('Hello from Node.js %s', process.version);
  res.end('Hello World');

Node Chrome Logger provide several logging methods on the ServerResponse (res) object:

  • res.chrome.log
