PWAs can leverage various modern web APIs to enhance functionality. Here are a few examples:

function openDatabase() {
  const request = indexedDB.open('myDatabase', 1);

  request.onupgradeneeded = event => {
    const db = event.target.result;
    db.createObjectStore('notes', { keyPath: 'id', autoIncrement: true });
  };

  request.onsuccess = event => {
    const db = event.target.result;
    console.log('Database opened:', db);
  };

  request.onerror = event => {
    console.error('Database error:', event.target.error);
  };
}

openDatabase();
