@react-native-module/node-libs-react-native

This package provides React Native compatible implementations of Node core modules like stream and http. This is a fork of node-libs-browser with a few packages swapped to be compatible in React Native.

Installation

This module has peerDependency "react", "react-native", "@react-native-module/pbkdf2"

npm install --save @react-native-module/node-libs-react-native @react-native-module/pbkdf2
yarn add @react-native-module/node-libs-react-native @react-native-module/pbkdf2

Usage

This package exports a mapping of absolute paths to each module implementation, keyed by module name. Modules without React Native compatible implementations are null.

These modules can be used with React Native Packager's metro.config.js or Webpack's resolve.alias.

Usage with React Native Packager

Add a metro.config.js file in the root directory of your React Native project and set resolver.extraNodeModules:

// metro.config.js
module.exports = {
  resolver: {
    extraNodeModules: require("@react-native-module/node-libs-react-native"),
  },
};

For more information, see this post on Node core modules in React Native.

Support additional packages

Some package not in extraNodeModules, but react-native's runtime run much slow or cannot

pbkdf2 is so slow in react-native's runtime randombytes is complain "Error: Secure random number generation is not supported by this browser. \nUse Chrome, Firefox or Internet Explorer 11"

If you wanna solve this Issue follow Steps

  1. Install babel-plugin-module-resolver
npm install --save-dev babel-plugin-module-resolver
yarn add -D babel-plugin-module-resolver
  1. Edit babel.config.js
// add lines

const nativeAlias = require('@react-native-module/node-libs-react-native/babelResolvers')

const nativePlugins = [
  [
    require.resolve('babel-plugin-module-resolver'),
    {
      alias: {
        ...nativeAlias
      },
    },
  ]
]

// add plugins to env (If you are not env, just add plugins)
module.exports = {
  presets: ['module:metro-react-native-babel-preset'],
  env: {
    production: {
      plugins: [...nativePlugins, 'react-native-paper/babel'],
    },
    development: {
      plugins: [...nativePlugins]
    },
    web: {
      plugins: [...myWebPlugins]
    }
  },
  ...
}
  1. And Just Run it

Globals

Node has certain globals that modules may expect, such as Buffer or process. React Native does not provide these globals. The @react-native-module/node-libs-react-native/globals module in this package will shim the global environment to add these globals. Just require (or import) this module in your app before anything else.

require("@react-native-module/node-libs-react-native/globals");
// ...
require("./app.js");

Modules

The following are the module implementations provided by this package. Some modules also have a "mock" implementation provided in the mock directory. These are replacements with minimal functionality.

Other React Native Modules

These are other React Native packages that implement Node core related modules. They are not included in node-libs-react-native, but you may find them useful separately.

dgram

react-native-udp implements Node's dgram API, but is not included here due to its native implementation and need to use react-native link.

fs

react-native-fs implement's Node's fs API, but is not included here due to its native implementation and need to use react-native link.

react-native-level-fs provides an alternative pure JavaScript implementation, using AsyncStorage as the underlying storage mechanism.

net

react-native-tcp implement's Node's net API, but is not included here due to its native implementation and need to use react-native link.

Credit

This is a fork of node-libs-browser with minor modifications and packages swapped out for React Native implementations. Thanks to those package authors for doing the hard work.
