Install the preferr-client using NPM or Yarn

npm install @preferr-app/preferr-client

yarn add @preferr-app/preferr-client

To authenticate Preferr and start tracking your A/B tests, you'll need to activate Preferr using your API key.

Somewhere in the root of your app, initialize Preferr like this:

import { Preferr } from "@preferr-app/preferr-client";

Preferr.init("XXXXXXXX") <--- After signing up, you'll have an API key

Now you're ready to create an A/B test!
