react-native-node-polyfill

This package is a polyfill of Node.js core modules for React Native (to use with Metro).

Important: It does not provide the compatibility layer with React Native library-based functions like node-libs-react-native, at least in this version.

The benefit of this package is that it is a simple polyfill for Node.js core modules, so there is zero dependency on any native module. Just pure javascript code to make it work.

All the polyfills were forked from rollup-plugin-polyfill-node. Thank You, all contributors, for a great job.

Installation

npm install @appidea/react-native-node-polyfill

Usage

Modify Your metro.config.js file to include the following:

const {getDefaultConfig, mergeConfig} = require('@react-native/metro-config');
const path = require('path');
// import the polyfill
const nodePolyfill = require('@appidea/react-native-node-polyfill');

/**
 * Metro configuration
 * https://facebook.github.io/metro/docs/configuration
 *
 * @type {import('metro-config').MetroConfig}
 */
const config = {};

module.exports = mergeConfig(getDefaultConfig(__dirname), nodePolyfill, config);
/*                                                        ^ ADD THIS ^ */
