The load-assets.js file also contains a method for creating a mock database instance:

const loadDb = () => {  const dbPath = path.resolve(assetsPath, 'db.json');  const adapter = new FileSync(dbPath);  return low(adapter);};

The loadDb() function loads the contents of /assets/db.json into an instance of lowdb. The default function exported from load-assets.js calls the loadWasm() and loadDb() functions and returns an object containing the mock database and Wasm instance:

module.exports = async function loadAssets() {  const db = loadDb();  const wasmInstance = await loadWasm();  return {    db,    wasmInstance  };};

Going forward, I'll use the term database to refer to the lowdb instance that accesses the db.json file. Now that ...
