Manifest Version

Published on • Updated on

Caution

Important: Chrome will be removing support for Chrome Apps on all platforms. Chrome browser and the Chrome Web Store will continue to support extensions. Read the announcement and learn more about migrating your app.

Applications are simply bundles of resources, wrapped up with a manifest.json file that describes the package's contents. The format of this file is generally stable, but occasionally breaking changes must be made to address important issues. Developers should specify which version of the manifest specification their package targets by setting a manifest_version key in their manifests.

Current Version

Chrome App developers must currently specify 'manifest_version': 2:

{
  ...,
  "manifest_version": 2,
  ...
}

Manifest version 1 only applied to extensions and hosted apps, not Chrome Apps. It was deprecated in Chrome 18.
