meteor-abtest

Simple AB testing framework for Meteor (modeled after Rails' split).

Usage

Install:

$ meteor add manuel:abtest

Return one of the alternatives to be used:

ABTest.start("Test Name", ['Alternative 1', 'Alternative 2', 'Alternative n'])

Return one of the weighted alternatives to be used:

ABTest.start("Test Name", { 
	'Alternative 1': 70, // Show 70% of the time
	'Alternative 2': 20, 
	'Alternative 3': 10 
})

Conclude the test for this user:

ABTest.finish("Test Name")

Example

Template.landing.helpers
  showRoundButton: -> ABTest.start('Landing Button', ['Normal', 'Round']) is 'Round'

Template.landing.events
  'click button': -> ABTest.finish('Landing Button')

Displaying the info

On the Client

{{> abtests }}

On the Server

Specify the Meteor IDs of the users who have permission to view the data.

ABTestServer.adminIds = ['user 1 id', 'user 2 id', 'user n id']

Example

Tracking Users

This library uses localStorage to keep track of the users. If localStorage is not available it uses cookies and if that fails it uses a session variable.

ABTests collection

You'll probably never need to do this but if you want you can query the ABTests collection.

ABTests.find() Example

{
	"_id" : "536a9a2c6935af1b3f0eec6d",
	"name" : "Welcome Message",
	"values" : {
		"Join Now" : {
			"started" : 15051,
			"finished" : 3827
		},
		"Get Started" : {
			"started" : 14984,
			"finished" : 3583
		}
	}
}
{
	"_id" : "536bd11553e89d2e75bd3cda",
	"name" : "Landing Improvements",
	"values" : {
		"Normal" : {
