react-native-browser-polyfill

A collection of polyfills for the react-native JavaScript environment.

If polyfills are needed to make browser-targeted libraries, which use commonly available functions/variables, work in react-native, this is the place to put them. Issues/PRs welcome.

Usage

npm install react-native-browser-polyfill the package and then require('react-native-browser-polyfill') it in your main entry file, before any libraries which require the polyfills.

Polyfills available in this package

global.self

Currently JavaScriptCore does not provide a self reference to the global object, which is utilized by browser libraries (i.e bluebird) to have a reliably reference to the global object which works in browsers and web-workers alike.

react-native-browser-polyfill's Issues

ES6/TS project should use import syntax not require

Finding that contrary to the README, just using require('react-native-browser-polyfill') is insufficient if it is followed by import statements (order of precedence?) in an ES6 project (mine is TypeScript with React Native).

The solution for me was:

import 'react-native-browser-polyfill'

as the first line in my main index file for the application. If others share this experience, perhaps it should be mentioned in the README?

ps. Thanks for the fix, was getting the dreaded self is not defined, but strangely it was only when debugging via VS Code React Native tools

don't suppose you know of a window.addEventListener polyfill for Reactive Native?
