IndexedDB

Noun · Development

Definitions

  1. A low-level browser API for storing large amounts of structured data (including files and blobs) client-side. Unlike localStorage, it's asynchronous, supports indexes, transactions, and cursors, and can store hundreds of MB. The storage backbone for offline-first web apps, used directly or through libraries like Dexie.js.

    In plain English: A full database built into your browser for storing large amounts of structured data, supporting offline web apps.

    Example: "Cache the full product catalog in IndexedDB — the app works offline and syncs changes when connectivity returns."
