I think there is a link in the article to make it happen but here is a possible solution.

In the src directory just make a file called createKeyPair.js and add this code:

// Shoutout to Nader Dabit for helping w/ this!
// twitter.com/dabit3

const fs = require('fs')
const anchor = require("@project-serum/anchor")

const account = anchor.web3.Keypair.generate()

fs.writeFileSync('./keypair.json', JSON.stringify(account))

Then inside your app run:
node createKeyPair.js
which should create a keypair.json (which is what holds the keypair for persistence)

Then in the App.js import the json file
import kp from './keypair.json'

and then whereever in your App.js you are calling:
let baseAccount = Keypair.generate();

Just replace with the following:

const arr = Object.values(kp._keypair.secretKey)
const secret = new Uint8Array(arr)
const baseAccount = web3.Keypair.fromSecretKey(secret)

That should be it. now it should be persistent on loading for anyone connected to your app.
