The '''Indexed Database API''' (commonly referred to as '''IndexedDB''') is a [[JavaScript]] [[application programming interface]] (API) provided by [[web browser]]s for managing a [[NoSQL]] [[database]] of [[JSON]] objects.

The '''Indexed Database API''' (commonly referred to as '''IndexedDB''') is a [[JavaScript]] [[application programming interface]] (API) provided by [[web browser]]s for managing a [[NoSQL]] [[database]] of [[JSON]] objects. It is a standard maintained by the [[World Wide Web Consortium]] (W3C).<ref>{{cite web|url = http://www.w3.org/TR/IndexedDB/|title = IndexedDB API|publisher = W3.org|access-date name="standard" 2015-12-04}}</ref>

As an alternative to the [[Web storage]] standard, IndexedDB can provide more storage capacity. Web storage has [[Web_storage#Storage_size|fixed limits]] per [[website]], but IndexedDB limits are "usually quite large, if they exist at all".<ref>{{cite web |title=Working with IndexedDB |url=https://developers.google.com/web/ilt/pwa/working-with-indexeddb |publisher=Google |access-date=19 January 2019}}</ref>

==History==

Support for IndexedDB was added to [[Firefox]] version 4,<ref>{{cite web|url=https://developer.mozilla.org/en/IndexedDB |title=IndexedDB - MDC Doc Center |publisher=Developer.mozilla.org |access-date=2011-02-18}}</ref> [[Google Chrome]] version 11,<ref>{{cite web|url=https://wwwchromestatus.chromium.orgcom/developersfeature/web-platform-status#TOC-Indexed-Database-API- 6507459568992256|title=WebIndexedDB - Chrome Platform Status|website=IndexedDB - Chrome Platform Status|publisher=The Chromium Projects |date=2012-05-21 |access-date=20122021-05-2415}}</ref> and [[Internet Explorer]] version 10.<ref>{{citation |url=http://msdn.microsoft.com/en-us/library/ie/hh673548(v=vs.85).aspx |title=IndexedDB |publisher=MSDN |date=2012-03-14 |access-date=2012-05-24}}</ref> [[Safari (web browser)|Safari]] added support in version 8.<ref>{{cite web|url=https://developer.apple.com/library/content/releasenotes/MacOSX/WhatsNewInOSX/Articles/MacOSX10_10.html#//apple_ref/doc/uid/TP40014484-SW1|title=What'sOS NewX inYosemite macOSv10.10 {{section-sign}} App Features|publisher=Apple|website=Apple Developers|access-date=2017-07-09|access-date=2021-05-15}}</ref>
