ethereumjs browser builds

This repository contains browser builds of certain ethereumjs libraries. They are built using browserify with a known set of working dependencies.

Usage

In your web application, include only one of the builds form the dist directory. All exports will be available under the global EthJS.

You should be import they first:

https://github.com/WoeOm/react-native-secure-randombytes https://github.com/WoeOm/react-native-safe-crypto

import { asyncRandomBytes } from 'react-native-secure-randombytes'
import safeCrypto from 'react-native-safe-crypto'
 
window.randomBytes = asyncRandomBytes
window.scryptsy = safeCrypto.scrypt

demo:

let code = await EthJs.Mnemonic.randomPhrase()
 
const derivePath = `m/44'/60'/0'/0/0`
let seedBuffer = EthJs.Mnemonic.phraseToSeed(code)
 
const key = EthJs.WalletHD.fromMasterSeed(seedBuffer);
 
const wallet = key.derivePath(derivePath).getWallet();
 
-------------------------
 
const wallet = await EthJs.Wallet.generate()

Note: all packages expect ECMAScript 6 (ES6) as a minimum environment. From browsers lacking ES6 support, please use a shim (like es6-shim) before including any of the builds from this repo.

Build

Run webpack to generate a new set up builds. Change package.json to require different versions of the libraries.
