Code Issues Releases Wiki Activity

Initial commit

Browse Source 
This is the very barebones beginnings of a demo implementation of an alternate tiddler store. It is not functional. If using the Vercel builds, open developer tools in the browser to see it failing due to the absence of basic wiki methods.

The plan is to build it up into the smallest possible plain JS wiki store implementation, sharing as much implementation as possible with the existing core implementation with as little code duplication as possible. It could then serve as the basis for future experiments with wiki stores based on SQLite (@linonetwo), or a custom append only database (@yaisog).
