WeExperiment

A thin abstraction layer for A/B testing.

Currently built on top of Split.io's JavaScript SDK.

This package is complemented by we-experiment-react.

Installation

npm install --save @wework/we-experiment-js

Usage

import weExperiment from 'we-experiment';
 
const experiments = weExperiment('USER_ID', 'SPLIT_API_KEY', {
  userAttributes: {
    // Optional user attributes
  }
});
 
experiments.getExperiment('foo')
  .then(experiment => {
    // experiment is a string equal to the user's experiment variant, or null.
  })
  .catch(error => {
    // we-experiment handles SDK init issues transparently, but in the unlikely event another error arises, you should catch it here
  });
 
experiments.getExperiments(['foo', 'bar'])
  .then(experiments => {
    /*
      experiments === {
                        foo: '...',
                        bar: '...'
                      }
     */
  });

Additional attributes

When getting experiments, it is possible to add additional attributes to the userAttributes supplied at initialization, or override existing attributes.

const experiments = weExperiment('USER_ID', 'SPLIT_API_KEY', {
  userAttributes: {
    foo: 'foo' // initial attributes
  }
});
 
experiments.getExperiment('bar', { bar: 'bar' }) // passed attributes are now { foo: 'foo', bar: 'bar' }
  .then(experiment => {})
  .catch(error => {});

Overrides

It is possible to override experiments by initializing the library like so:

weExperiment('USER_ID', 'SPLIT_API_KEY', {
  experimentOverrides: {
    foo: 'variant_1',
    bar: 'variant_2'
  }
});

Additional Split.io options

It's possible to pass additional options to the Split.io library in the following way:

weExperiment('USER_ID', {
  // ...
  extraOptions: {
    // Split.io factory options here
  }
});

For more information on the possible options, see: http://docs.split.io/docs/javascript-sdk-overview#section-advanced-configuration-of-the-sdk

Note that core.authorizationKey and core.key are already passed as apiKey and userId respectively.
Additionally, features are passed in as experimentOverrides.
