Example of how Dexie's new liveQuery() function works

observe-old-friends.js

import Dexie, { liveQuery } from "dexie";

const db = new Dexie('MyDatabase');
db.version(1).stores({
  friends: '++id, name, age'
});

const friendsObservable = liveQuery (
  () => db.friends
    .where('age').above(75)
    .toArray()
);

friendsObservable.subscribe({
  next: result => console.log("Got result:", result),
  error: error => console.error(error)
});

setTimeout(() => db.friends.add({name: "Joe", age: 78}), 1000);
