Readme

Console Hook
Hook into the console for transparent log recording in production and log capture for testing.
npm install console-hook

Works in the browser too, just grab console-hook/index.js.

Examples

Intercept all console method calls

var Hook = require('console-hook');
var myHook = Hook().attach((method, args) => {
  // method is the console[method] string
  // args is the arguments object passed to console[method]
});

// okay, we're done playing with the console stuffs
myHook.detach();

Intercept all console method calls and don't call console

var Hook = require('console-hook');
var silence = true; // could be `isProduction`
var myHook = Hook(console, silence).attach((method, args) => {
  // method is the console[method] string
  // args is the arguments object passed to console[method]
});

// okay, we're done playing with the console stuffs
myHook.detach();

Intercept only console.error calls

var Hook = require('console-hook');
var myHook = Hook().attach('error', (method, args) => {
  // method is the console[method] string, always "error"
  // args is the arguments object passed to console[method]
});

// okay, we're done playing with the console stuffs
myHook.detach();

Use another console-like Logger

// if you have an Ember app and already use Ember.Logger
var Hook = require('console-hook');
var myHook = Hook(Ember.Logger).attach((method, args) => {
  // method is the console[method] string
  // args is the arguments object passed to console[method]
});

// okay, we're done playing with the console stuffs
myHook.detach();

Contributing

Contributions are incredibly welcome as long as they are standardly applicable and pass the tests (or break bad ones). Tests are written in Mocha and assertions are done with the Node.js core assert module.
# running tests
npm run test
