Split JavaScript SDK for Browsers

Overview

This SDK is designed to work with Split, the platform for controlled rollouts, which serves features to your users via feature flags to manage your complete customer experience.

Compatibility

The JS Browser SDK is a library for Web browser environments.

The library was build to support ES5 syntax and all major browsers. However, there are a few polyfills that would be required when targeting old browsers that don't have native support for Promises, Maps, Sets and Fetch Web API. You should include a polyfill, like es6-promise for Promises, and whatwg-fetch or the lightweight unfetch for the Fetch API.

Getting started

Below is a simple index.js example that describes the instantiation and most basic usage of our SDK:

// Import the SDK
import { SplitFactory } from '@splitsoftware/splitio-browserjs';

// Instantiate the SDK
var factory = SplitFactory({
  core: {
    authorizationKey: 'YOUR_SDK_KEY',
    key: 'CUSTOMER_ID'
  }
});

// Get the client instance you'll use
var client = factory.client();

// Set a callback to listen for the SDK_READY event, to make sure the SDK is properly loaded before asking for a treatment
client.on(client.Event.SDK_READY, function() {
  var treatment = client.getTreatment('FEATURE_FLAG_NAME');
  if (treatment == 'on') {
    // insert code here for on treatment
  } else if (treatment == 'off') {
    // insert code here for off treatment
  } else {
    // insert your control treatment code here
  }
});
