@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.

[node-libs-browser]: https://www.npmjs.com/package/node-libs-browser

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.

$3

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

`js
// 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][post].

$3

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
`

2. Edit babel.config.js

`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]
}
},
...
}
`

3. And Just Run it

$3

Node has certain globals that modules may expect, such as Buffer or process. React Native does not provide these globals. The [node-libs-react-native/globals][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.

[globals]: ./globals.js

`js
require("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.

$3

[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.

[react-native-udp]: https://github.com/tradle/react-native-udp

$3

[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-fs]: https://github.com/itinance/react-native-fs

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

$3

[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.
