prereqs:

• some experience using gun and sea
• node_version 16
• react-native dev env = https://reactnative.dev/docs/0.70/environment-setup

Step 1: react-native bare template

npx react-native init AwesomeProject

or specific version (see versions set in 2 spots) *using prereqs

npx react-native@0.70.6 init AwesomeProject --version 0.70.6

Step 2: install packages

npm install text-encoding buffer   #for gun/sea deps
npm install github:bmatusiak/gun-rebuild github:bmatusiak/gun-rebuild-sea github:amark/gun   #for gun/sea
npm install react-native-webview react-native-webview-crypto react-native-get-random-values  #for crypto
npm install @react-native-async-storage/async-storage   #for gun storage

Step 3: load gun (App.js)

import React, {useRef, useEffect} from 'react';
import PolyfillCrypto from 'react-native-webview-crypto';
import 'react-native-get-random-values';
import 'gun/lib/mobile';
import Gun from 'gun';
import 'gun/sea';
import 'gun/lib/radix.js';
import 'gun/lib/radisk.js';
import 'gun/lib/store.js';
import AsyncStorage from '@react-native-async-storage/async-storage';
import asyncStore from 'gun/lib/ras.js';

export default function App() {
  var gun = (gun_ref => {
    if (gun_ref.current == null) {
      gun_ref.current = Gun({
        peers: 'https://gun:8765/gun',
        store: asyncStore({AsyncStorage}),
      });
    }
    return gun_ref.current;
  })(useRef(null));
  useEffect(function () {
    (async function () {
      var pair = await Gun.SEA.pair();
      gun.user().auth(pair, function () {
        console.log(gun.user().is);
      });
    })();
  }, []);
  return (
    <>
      <PolyfillCrypto />
    </>
  );
}

What just happened?

The above example should output the current logged in user in the console. That's it, nothing in the the app is displayed.
