console-proxy

minimal console proxy for the browser and Node.js

This module allows you to intercept console messages on all browsers and on Node.js. It will not override the global console object. Stubs are created for environments where console methods are not implemented.

Tested on IE7-IE10, Chrome, Safari and Firefox

Installation

$ npm install console-proxy

Usage

Include the library on Node.js

var consoleProxy = require('console-proxy');

or include the script for browser (0.44 KB gzipped) usage

 <script src="https://raw.github.com/bermi/console-proxy/master/dist/console-proxy.min.js" type="text/javascript"></script>

Create a console proxy

var console = consoleProxy.getConsole({
    log: function () {
      var args = Array.prototype.slice.apply(arguments);
      args.unshift("[info]", new Date());
      // pass arguments for the base console.log or false to
      // prevent it from being called
      return args;
    }
  });

console.log("Hello", "world");
//=> [info] Sat Apr 27 2013 15:38:56 GMT+0200 (CEST) Hello world

console.[error/info/memory/profile] will continue working as expected unless they are explicitly proxied

For a crossbrowser console example see examples/browser.html

Getting the original console

If you want a reference to the unproxied console you can do so with

var originalConsole = consoleProxy.getOriginalConsole();
