What is this?
A higher-order function to provide an A/B testing mechanism with multiple weights.
How do I install it?
npm install ab-test-fn
How can I use it?
Use-case #1 - Simple A/B testing
In this scenario, we want to test two versions of a function, fnA
and fnB
, and we want to run fnA
80% of the time and fnB
20% of the time.
import { AB } from 'ab-test-fn';
const fnA = () => console.log('fnA');
const fnB = () => console.log('fnB');
const fnAB = AB(fnA, fnB, [0.8, 0.2]);
fnAB(); // Will log 'fnA' 80% of the time and 'fnB' 20% of the time
Use-case #2 - A/B testing with multiple weights
In this scenario, we want to test three versions of a function, fnA
, fnB
and fnC
, and we want to run fnA
50% of the time, fnB
30% of the time and fnC
20% of the time.
import { AB } from 'ab-test-fn';
const fnA = () => console.log('fnA');
const fnB = () => console.log('fnB');
const fnC = () => console.log('fnC');
const fnABC = AB(fnA, fnB, fnC, [0.5, 0.3, 0.2]);
fnABC(); // Will log 'fnA' 50% of the time, 'fnB' 30% of the time and 'fnC' 20% of the time
API
The AB
function accepts an indefinite number of functions and an array of weights. The weights can be either integers or floats, they don't have to add up to 1. The function will return a new function that will run one of the provided functions based on the sum of the weights.
Tests
You can run the tests by using the following command:
npm test
