You will need to use the nodejs version of tiddlywiki to execute commands that will âtake apartâ the html into separate files. The command I use is
tiddlywiki --load /path/to/singfile/wiki.html --savewikifolder .
note the â.â at the end to indicate the current directory.
Here is the âsavewikifolderâ command: https://tiddlywiki.com/#SaveWikiFolderCommand
Now that you have the folder with your tiddlers in them you would then need to render them as html files. Refer to the instructions for generating a static site for that, again using nodejs tiddlywiki : https://tiddlywiki.com/#Generating%20Static%20Sites%20with%20TiddlyWiki
Definitely look into using the nodejs version of tiddlywiki. Your tiddlers are stored as individual files and you can do some fancy things with them like automagically moving tagged images/tiddlers into subfolders. ( see https://tiddlywiki.com/#ExternalImages and File System Paths under https://tiddlywiki.com/#Customising%20Tiddler%20File%20Naming )
Good luck!
