A proof-of-concept inspired and enabled by Hosting SQLite Databases on Github Pages and the ensuing Hacker News post. The compiled single-page app supports autocomplete for titles, automatic redirecting & other MediaWiki datasets like WikiQuote or Chinese Wikipedia. It makes no external API calls except to get Wikipedia's images.
Seems ideal for making offline copies of Wikipedia (or other Mediawiki installs, it's implied) available.

Has instructions for turning an XML dump of Wikipedia into a SQLite database; unfortunately it uses node.js.
