@eppo/node-server-sdk

Eppo Server-Side SDK for Node.js

API Reference

Getting Started

1. Install the Eppo SDK as a dependency of your application:

yarn add @eppo/node-server-sdk

1. Initialize the SDK client in your application code

import * as EppoSdk from '@eppo/node-server-sdk';

const eppoClient = EppoSdk.init({ apiKey: 'YOUR_API_KEY' });

The client must be a singleton. The client instance stores assignment configurations in memory. To avoid inconsistent assignment results, the same client instance should be reused across requests. Invoke the init method once at application startup to generate the client.
