Git pre-commit Hooks

The pre-commit file listed here is setup to scan files for invalid keywords prior to commit to avoid debug or logging information making its way into production files. Right now it is setup to scan only .js and .coffee files for the following keywords:

KEYWORDS_REGEX="console\.(debug|info|log|warn)\(|alert\(|debugger"
EXTENSIONS_REGEX="(.js$|.coffee$)"

Installing the Hook

This article has been given a more permanent home on my blog. Also, since it was first written, the development of the Promises/A+ specification has made the original emphasis on Promises/A seem somewhat outdated.

You're Missing the Point of Promises

Promises are a software abstraction that makes working with asynchronous operations much more pleasant. In the most basic definition, your code will move from continuation-passing style:

getTweetsFor("domenic", function (err, results) {
 // the rest of your code goes here.

	var Item = React.createClass({
	render: function() {
	return(
	<li>
	... Item goes here ...
	<input type="checkbox" checked={this.props.selected} onChange={this.onChange} />
	</li>
	);
	},
	onChange: function(event) {

	# Test setup, with jasmine-given
	Given -> spyOn(Backbone.Model.prototype.fetch, 'call').andReturn
	done: (callback) -> callback()

	# Source, fetch override in model
	fetch: (options) ->
	Backbone.Model.prototype.fetch.call(@, options).done @callback

	#!/usr/bin/env ruby

	Given -> spyOn(@car, "get")
	Given -> @car.get.when('phone').thenReturn("123-456-789")
	Given -> @car.get.when('name').thenReturn("juice")

	Then -> expect(@car.get).toHaveBeenCalledWith('phone')
	Then -> expect(@car.get).toHaveBeenCalledWith(jasmine.any(String))
	Then -> expect(@car.get).toHaveBeenCalledWith jasmine.argThat (arg) ->
	arg.length < 5
