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

`` bash
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

`javascript
// 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.
