How to Conduct an A/B Test in Elixir

Read the blog post here

This repository contains the accompanying sample code for the blog article titled 'How to Conduct an A/B Test in Elixir' The application relies on a web-based framework for Elixir called Pheonix to serve the app through the browser. To conduct the A/B test experiment, I've integrated ConfigCat feature flags for switching between and deploying each version to the user sample set. Additionally, I've incorporated Amplitude's data analytics platform to track and compare the clicks from each version, to decide on the best one.

Getting started

Prerequisites

• An installation of Elixir
• An installation of Pheonix - A framework for building Elixir-based web apps.

Build

1. Clone this repository
2. Create a .env file in the root of the repo with the following content. Then replace the placeholder values with your own:

AMPLITUDE_API_KEY="YOUR-AMPLITUDE-API-KEY-GOES-HERE"
CONFIGCAT_SDK_KEY="YOUR-CONFIGCAT-SDK-KEY-GOES-HERE"

3. Install the dependencies:

mix setup

Run

1. Start Phoenix endpoint with:

mix phx.server

Now you can visit localhost:4000 from your browser.
