expo-symbol-crypto

A crypto alternative package for running symbol-sdk on Expo managed React Native environment.

Setup

1. Expand the Expo template and add symbol-sdk.
2. Configure metro.config.js.

npx create-expo-app my-app
npm install symbol-sdk@2 buffer events readable-stream expo-symbol-crypto

// Learn more https://docs.expo.io/guides/customizing-metro
const { getDefaultConfig } = require("expo/metro-config");

const config = {
  ...getDefaultConfig(__dirname),
  resolver: {
    extraNodeModules: {
      crypto: require.resolve("expo-symbol-crypto"),
      stream: require.resolve("readable-stream"),
      buffer: require.resolve("buffer"),
      events: require.resolve("events"),
    },
  },
};

module.exports = config;

Then add ./shim.js to project root.

global.process = require("process");
process.browser = false;
if (typeof Buffer === "undefined") global.Buffer = require("buffer").Buffer;

Finally, import on App.js

import "./shim";
import { StatusBar } from "expo-status-bar";
import { StyleSheet, Text, View } from "react-native";

export default function App() {
  return (
    <View style={styles.container}>
      <Text>Open up App.js to start working on your app!</Text>
      <StatusBar style="auto" />
    </View>
  );
}

const styles = StyleSheet.create({
  container: {
    flex: 1,
    backgroundColor: "#fff",
    alignItems: "center",
    justifyContent: "center",
  },
});
