Dexie.js
A Minimalistic Wrapper for IndexedDB
...What good is any development tool without great documentation? Dexie is thoroughly explained, and examples are available to help you on your way. Dexie has near-native performance. Its bulk operations utilize an often-overlooked feature in IndexedDB, ignoring success callbacks when possible. Offline databases are groovy! But without keeping the database in sync with a server, you're missing a great deal. Dexie.js solves these limitations and provides a neat database API. Dexie.js aims to be the first-hand choice of a IDB Wrapper Library due to its well thought-through API design, robust error handling, extendability, change tracking awareness and its extended KeyRange support (case insensitive search, set matches and or operations).
