IndexedDB with usability

idb is a small JavaScript library that makes the browser's IndexedDB API easier to use without replacing its core model. It largely mirrors native IndexedDB while converting IDBRequest results into promises. Developers can open, upgrade, and delete databases through concise asynchronous helpers. Enhanced database, transaction, store, and cursor objects reduce boilerplate while remaining close to the platform API. The library also provides wrapping and unwrapping helpers for moving between enhanced and native IndexedDB objects. It supports modern browsers, TypeScript, schema upgrades, transaction helpers, and asynchronous cursor iteration.
