The JavaScript SDK can be used in browser and is distributed through:

• npm
• yarn
• a prebuilt UMD bundle of the JavaScript SDK, which allows installing the SDK via an HTML .

npm install --save @optimizely/optimizely-sdk

yarn add @optimizely/optimizely-sdk

<script src="https://unpkg.com/@optimizely/optimizely-sdk/dist/optimizely.browser.umd.min.js"></script>

🚧

Note

We do not recommend using the unpkg script tag installation method in production as it introduces a third-party performance dependency, and will not be explicitly version-locked by default

The full source code is at https://github.com/optimizely/javascript-sdk/tree/master/packages/optimizely-sdk.

Requirements

The JavaScript SDK requires an ES5-compatible environment, as well as Promise. To run in environments that don't support Promise, you can use promise-polyfill.

Next

After installing, you need to intialize the SDK.
