What prefix for _canonical_uri?

[RA]

Trying to add FontAwesome as a plugin. The wiki is working, the plugin is recognized, and it contains shadow tiddlers for each svg file.

The only part I cannot get right is the _canonical_uri, so I get a "broken image" icon in each shadow tiddler instead of an svg image.

The documentation says "The URI can be absolute or relative to the HTML document."

What is the location of "HTML document" in case of Node.js? Is it where tiddlywiki.js is, or where tiddlywiki.info is? Or the current path in the shell where I'm launching the nodejs command from?

What should I set the prefix to? Is it even possible for _canonical_uri to point to a relative path that is outside the "HTML document"?

My wiki URL is

http://<ip address>:<port>/work

The tiddlywiki command:

nodejs /srv/TiddlyWiki5/app/tiddlywiki ++/srv/TiddlyWiki5/plugins/fontawesome /srv/TiddlyWiki5/wikis/work --listen host=0.0.0.0 port=8083 'root-tiddler=$:/core/save/lazy-all' 'path-prefix=/work'

Filesystem structure:

/srv/TiddlyWiki5/
  app/tiddlywiki.js
  plugins/fontawesome/tiddlywiki.files
  plugins/fontawesome/svgs/regular/*.svg
  wikis/work/tiddlywiki.info
  wikis/work/tiddlers/*.tid

tiddlywiki.files (cannot get the prefix right):

{
    "directories": [
        {
            "path": "svgs/regular",
            "filesRegExp": "^.*\\.svg$",
            "isTiddlerFile": false,
            "fields": {
                "title": {"source": "basename-uri-decoded"},
                "created": {"source": "created"},
                "modified": {"source": "modified"},
                "type": "image/svg+xml",
                "_canonical_uri": {"source": "filename", "prefix": "<what should I put here?>"}
            }
        }
    ]
}

Hi RA

Trying to add FontAwesome as a plugin. The wiki is working, the plugin is recognized, and it contains shadow tiddlers for each svg file.

If you’re using _canonical_uri, then the SVGs would also need to be exposed via HTTP. You could put them in the “files” folder of the wiki:

https://tiddlywiki.com/#Using%20the%20integrated%20static%20file%20server

If you went that route you should be able to use `files/` as the prefix.

I’d be inclined to not bother with _canonical_uri, and instead embed the SVG text fields as shadow tiddlers.

Best wishes

Jeremy.
