ReactNative BitcoinJS (react-native-bitcoinjs-lib)

A javascript Bitcoin library for node.js and browsers.

ReactNative-ready fork of the original bitcoinjs package. Used by over a million wallet users and the backbone for almost all Bitcoin web wallets in production today.

Should I use this in production?

If you are thinking of using the master branch of this library in production, stop. Master is not stable; it is our development branch, and only tagged releases may be classified as stable.

Installation

npm i react-native-bitcoinjs-lib --save

Installation

npm install bitcoinjs-lib

Typically we support the Node Maintenance LTS version. If in doubt, see the .travis.yml for what versions are used by our continuous integration tests.

Create the react native project.

react-native init fooApp

Install rn-nodeify to be able to use Node.js libs.

npm i rn-nodeify -g

Add this postinstall script to install & hack the Node.js libs for the usage in React Native.

"postinstall": "rn-nodeify --install stream,buffer,events,assert --hack"

Install & link required dependencies.

npm i react-native-bitcoinjs-lib react-native-randombytes --save && react-native link react-native-randombytes

Run the postinstall, it will create a shim.js file which you need to include in your index file (see Usage).

npm run postinstall

Run the app

react-native run-android or react-native run-ios

Usage

Edit index.android.js and index.ios.js

// node.js libs
import './shim' // make sure to use es6 import and not require()
import Bitcoin from 'react-native-bitcoinjs-lib'
[...]
const keypair = Bitcoin.ECPair.makeRandom()
console.log(keypair.getAddress()) // your brand new base58-encoded Bitcoin address

Examples

Run the example app or refer to the original repository for more available examples.
