Indexed Database API

The Indexed Database API (commonly referred to as IndexedDB) is a <a href="/facts/JavaScript/XhhIIEsl">JavaScript</a> <a href="/facts/Application_programming_interface/GMlN4vUr">application programming interface</a> (API) provided by <a href="/facts/Web_browser/2pfyymLs">web browsers</a> for managing a <a href="/facts/NoSQL/vvynRKfd">NoSQL</a> <a href="/facts/Database/VYcpkevb">database</a> of objects. It is a standard maintained by the <a href="/facts/World_Wide_Web_Consortium/lGWmhF6M">World Wide Web Consortium</a> (W3C).
As an alternative to the <a href="/facts/Web_storage/kD85jwCw">Web storage</a> standard, IndexedDB can provide more storage capacity. Web storage has <a href="/facts/Web_storage/kD85jwCw">fixed limits</a> per <a href="/facts/Website/SAsjJnca">website</a>, but IndexedDB limits are "usually quite large, if they exist at all".
<a href="/facts/Use_case/8pNHjsIr">Use cases</a> for IndexedDB include caching <a href="/facts/Web_application/BLkF3BIN">web application</a> data for <a href="/facts/Offline/rhxAKfol">offline</a> availability. Some browser modules, such as <a href="/facts/Web_development_tools/MLvfsYH6">devtools</a> or <a href="/facts/Browser_extension/jzkeh57V">extensions</a>, may also use it for storage.
