It also allows to register context menus without providing actual markup, as $.contextMenu generates DOMElements as needed.have a look at the demos.

IndexedDBShim - A polyfill for IndexedDB using WebSql

•    Javascript

Important note to those upgrading from version 2: Besides some backward-breaking (though standard-compliant) behavioral fixes (see CHANGES), there are changes coming in version 3 which will also unfortunately cause data stored under version 2 to break. We are not able to provide you with an automated upgrade path, so you will need to either stick with version 2 or migrate users' data yourself to the new SQL storage format (whose changes are considerable; CHANGES also lists these breaking database format changes). We have attempted to anticipate future changes so that for another upgrade, even a major one, old data will hopefully continue to work. However, to be safe, if you are using npm, be sure to specify semver targets in your dependencies properly so as to avoid allowing for automated upgrades to the next major version in case another future upgrade may also need to introduce breaking changes to the data format, thereby breaking old data. Use a single, indexable, offline storage API across all desktop and mobile browsers and Node.js.

document-register-element - A stand-alone working lightweight version of the W3C Custom Elements specification

•    Javascript
