Web apps have had offline capabilities like saving large data sets and binary files for some time now. You can even do things like that you could write an app that cache MP3 files. Browser technology can store data offline and plenty of it. The problem, though, is that the technology choices for how you do this are fragmented.
localStorage gets you really basic data storage, but it's slow and can't handle binary blobs. IndexedDB and WebSQL are asynchronous, fast, and support large data sets, but their APIs aren't very straightforward. Even still, neither IndexedDB nor WebSQL have support from all of the major browser vendors and that doesn't seem like something that will change in the near future.
If you need to write a web app with offline support and don't know where to start, then this is the article for you. If you've ever tried to start working with offline support but it made your head spin, this article is for you to
An ongoing project to catalogue all of these sneaky, hidden, bleeding edge selectors as I prepare my JSConf EU 2012 talk.
Everything is broken up by tag, but within each the selectors aren't particularly ordered.
