@checkgate/react-native

Checkgate React Native SDK (JSI) — The official high-performance mobile client for Checkgate. Powered by a direct JSI (JavaScript Interface) natively bridging to Rust, this SDK completely avoids strictly serialized asynchronous React Native bridge delays, allowing sub-microsecond synchronous feature toggle evaluations natively on device.

Installation

npm install @checkgate/react-native
# iOS requires pod installation
cd ios && pod install

Quick Start

Plug the incredibly fast evaluating CheckgateProvider context or native clients directly into your React Native app.

import { CheckgateNativeClient } from '@checkgate/react-native'

const client = new CheckgateNativeClient({
  serverUrl: 'https://checkgate.your-company.com',
  sdkKey: 'pk_mobile_xxxxxx'
})

// Run this during app initialization
client.connect()

// Later natively inside your RN component lifecycle
function CheckoutScreen({ user }) {
  const showApplePay = client.isEnabled('apple-pay-checkout', user.id, { plan: user.plan })
  
  return showApplePay ? <ApplePayButton /> : <StandardCheckout />
}

Why Checkgate JSI?

• Synchronous Native Bridge: Unlike standard HTTP wrappers, Checkgate's JSI evaluates flag arrays in memory avoiding async JS bridge loading.
• Bandwidth Conscious: Streamlined SSE prevents apps from polling the network heavily on metered mobile plans.
