Internet Explorer 10 and Windows Store apps using JavaScript introduce support for the Indexed Database API ("IndexedDB"). IndexedDB enables you to store structured data. Unlike cookies and DOM Storage, IndexedDB provides features that enable you to group, iterate, search, and filter JavaScript objects.

Microsoft Edge brings a number of improvements to IndexedDB, including:

  • Local use: Indexed Database now supports webpages loaded via a "file://" URI scheme. This allows developers accessing files from disk to use these APIs.
  • Removal of soft limits: Indexed Database and Application Cache will not request user authorization to use more than 10 megabytes of space.
  • Changes to default hard limits: Indexed Database limits are removed for Windows Store apps using JavaScript.
