React Native SDK

Featurevisor SDK can be used with React Native for evaluating feature flags when building iOS and Android applications.

Installation#

You can use the same Featurevisor React SDK in your React Native app. Just install it as a regular dependency:

$ npm install --save @featurevisor/react

See @featurevisor/react API docs here.

Example usage#

// ./MyComponent.js
import { Text } from 'react-native'
import { useFlag } from '@featurevisor/react'
export default function MyComponent() {
  const featureKey = 'my_feature'
  const context = {
    // ...additional context
  }
  const isEnabled = useFlag(featureKey, context)
  return <Text>Feature is {isEnabled ? 'enabled' : 'disabled'}</Text>
}

Polyfills#

The only extra polyfill you might need is for the TextEncoder API.

You can consider using fastestsmallesttextencoderdecoder package for that.

Example repository#
