I am using Tiddlywiki for small searchable wikis. It is quite compact and runs in a browser. The HTML version, that is.
Now there is a Node version that works very well and offers a few benefits but also drawbacks. In brief,
- External links now can be used, as opposed to when using the TiddlyDesktop
- easier upgrade process
- Requires installation of Node.js
The posts are now split in separate files, which is preferrable but I can't put that into either Pros nor Cons. The served directory is clean and therefore easy to sync via cloud. It contains only one small info file in addition to your content.
