i got web3 up and running with RN59 and React 16.8
react-native init APPNAME
npm i --save react-native-crypto
npm i --save react-native-randombytes
react-native link react-native-randombytes
npm i --save-dev rn-nodeify@latest
./node_modules/.bin/rn-nodeify --install
npm i --save node-libs-browser
modify APPNAME/metro.config.js to read:
const extraNodeModules = require('node-libs-browser');
module.exports = {
resolver: {
extraNodeModules,
},
transformer: {
getTransformOptions: async () => ({
transform: {
experimentalImportSupport: false,
inlineRequires: false,
},
}),
},
};
modify shim.js to read:
if (typeof __dirname === 'undefined') global.__dirname = '/'
if (typeof __filename === 'undefined') global.__filename = ''
if (typeof process === 'undefined') {
global.process = require('process')
} else {
const bProcess = require('process')
for (var p in bProcess) {
if (!(p in process)) {
process[p] = bProcess[p]
}
}
}
process.browser = false
if (typeof Buffer === 'undefined') global.Buffer = require('buffer').Buffer
if (typeof location === 'undefined') global.location = { port: 80, protocol: 'https:' }
const isDev = typeof __DEV__ === 'boolean' && __DEV__
process.env['NODE_ENV'] = isDev ? 'development' : 'production'
if (typeof localStorage !== 'undefined') {
localStorage.debug = isDev ? '*' : ''
}
// If using the crypto shim, uncomment the following line to ensure
// crypto is loaded first, so it can populate global.crypto
require('crypto')
import './shim' in App.js
npm i --save web3
