I love TiddlyWiki. I've been developing a highly non-linear document for some conceptual documentation with it at work.

If you want to see what you can really do with TW, or want to learn how, check out Grok TiddlyWiki (https://groktiddlywiki.com/read/)

I built a personal chess knowledge base with it too. I added a content-type that let me just paste in a plain-text representation of the game and it would display the game with an interactive board.

I have your book saved on my Tiddly server :)

Any chance you could share the chess one? That sounds awesome.

I am not the author of the book!

As far as the wiki: It's not hosted. It's just on my local machine. You basically just drop the minified JS library in a tiddler and then create a custom widget type and a ViewTemplate to automatically display the widget when the content-type is the correct one.

I used http://whatfettle.com/2008/05/TiddlyProcessing/ as the basis (although it's old) and the main docs on creating a custom widget (https://tiddlywiki.com/dev/#Javascript%20Widget%20Tutorial)

This is the best Tiddly server I've come across. I was running the NodeJS version for a few weeks before I switched over. I think I saw it on HN awhile ago.

Was fairly easy to set-up https://tiddly.packett.cool/

I've started using TW in the past days with the goal of setting up a cookbook + meal planner with nutritional values computes from the ingredients.

It feels very malleable/hackable, I'm happy with my progress so far, the biggest annoyance is that as far as I can tell the JavaScript API is not documented anywhere.

Initially I looked at Decker and LÖVE, but the former is not suitable for a phone screen and the latter isn't meant for UIs. I would have preferres a non-web solution but TW is a solid choice nonetheless.

I'm an ardent user of Tiddly Wiki as a knowledge database.

I know there's Obsidian and Logseq, but they feel like too much overhead to me.

TiddlyWiki does all of that, and it's a self-contained single HTML file. You can run it on Node.js, but you don't have to.

Oh, and also it's a journal and a blog.

I built my ADHD wiki[1] with it, and I don't think I'd have had the energy to do it with any other tool.

If anyone has any TWs they work on in public, please post your links. I'd like to read them.
