Questions tagged [indexeddb]
indexedDB provides a way to store data in the browser using Javascript. Unlike relational databases, indexedDB uses a key-value store that is conceptually similar to HTML5's local storage. However, indexedDB is better than local storage for storing large amounts of data and for querying data more quickly. indexedDB is supported in IE, Chrome, Firefox, and Microsoft Edge, although support for specific features varies.
