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
As an alternative to the [[Web storage]] standard, IndexedDB can provide more storage capacity. Web storage has [[
[[Use case]]s for IndexedDB include caching [[web application]] data for [[offline]] availability.<ref>{{cite web |title=Using IndexedDB |url=https://developer.mozilla.org/en-US/docs/Web/API/IndexedDB_API/Using_IndexedDB |website=MDN |publisher=Mozilla |access-date=19 January 2019}}</ref> Some browser modules, such as [[Web development tools|devtools]] or [[browser extension|extensions]], may also use it for storage.
==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 |archive-date=2012-05-26 |archive-url=https://web.archive.org/web/20120526230025/https://developer.mozilla.org/en/IndexedDB |url-status=dead }}</ref> [[Google Chrome]] version 11,<ref>{{cite web|url=https://chromestatus.com/feature/6507459568992256|title=IndexedDB - Chrome Platform Status|website=IndexedDB - Chrome Platform Status|publisher=The Chromium Projects |date=2012-05-21 |access-date=2021-05-15}}</ref> [[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]] 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=OS X Yosemite v10.10
[[Web SQL Database]] was a prior API developed by [[Apple Inc.|Apple]].<ref>{{cite web|last=Shankland|first=Stephen|url=https://www.cnet.com/news/consensus-emerges-for-key-web-app-standard/|title=Consensus emerges for key Web app standard | Deep Tech - CNET News |publisher=News.cnet.com |date=2010-03-12 |access-date=2011-02-18}}</ref> But Firefox refused to add support for it and argued against it becoming a standard because it would codify the quirks of [[SQLite]].<ref>{{cite web|url=https://robert.ocallahan.org/2010/06/not-implementing-features-is-hard_03.html|archive-url=https://web.archive.org/web/20201109032423/http://robert.ocallahan.org/2010/06/not-implementing-features-is-hard_03.html|title=Well, I'm Back: Not Implementing Features Is Hard|author-first=Robert|author-last=O'Callahan|publisher=Weblogs.mozillazine.org|date=2010-06-04|access-date=2011-02-18|archive-date=

==Performance==
Because IndexedDB is running inside of the security sandbox of a browser, all operations have to go through various security layers which decreases the performance of IndexedDB. With IndexedDB 2.0<ref name="w3c-blog-indexeddb-2.0">{{Cite web|url=https://www.w3.org/blog/news/archives/6795|title=Indexed Database API 2.0 is now a W3C Recommendation {{!}} W3C News|website=W3C News|author=W3C|date=2018-01-30|access-date=2021-05-16}}</ref> the getAll() method was added which allows to improve performance on bulk read operations.
