tiddlywikid

A server implementation in goling for TiddlyWiki, base on TiddlyWeb plugin for tiddler store (for saved tiddlers).

features

• no dependency, one executable file with a base image of wiki will work.
• use browser cache by default, tiddlers won't send again if there were no update
  • the build-in server of TiddlyWiki will calculate the md5 of tiddler every time when browser request that tiddler, it will wasting CPU and let latency longer.
• auto generated tiddler
  • $:/sync-time: return last time of fetching tiddlers
  • $:/client-ip: return IP of wiki user
• provide attachment api (with plugin) for binary files/large tiddlers, avoiding slowing down whole wiki.
• more permission control: multiple users, allow/block by IP range.

• -tiddler-size-limit - size limit for a tiddler
• -parse-limit - limit the memory usage for parsing when file uploading

base image

Base image is a html file of TiddlyWiki with TiddlyWeb plugin installed. Plugins must be pre-baked into the TiddlyWiki file, they can not be load via lazily loaded Tiddlers currently. The cmd/index.html is 5.2.6-prerelease (wiki core patch for file MIME issue) with the TiddlyWeb, Highlight, Internals, TiddlyWeb External Attachments plugins added. There are several ways to build/get the base image.

by cli

• npm install tiddlywiki
• npx tiddlywiki srv --init server : init client-server version in srv directory
• edit srv/tiddlywiki.info
  • build >> index
    • change "$:/plugins/tiddlywiki/tiddlyweb/save/offline" to "$:/core/save/all"
  • plugins: add more plugins if you want
• npx tiddlywiki srv --build index : build index.html with plugin tiddlywiki/tiddlyweb
  • copy srv/output/index.html

by manually

• open a empty tiddlywiki (can download from TiddlyWiki website) in web browser
• click the control panel (gear) icon
• click the Plugins tab
• click Get more plugins
• click Open plugin library
• find TiddlyWeb plugin and click install
• A bar at the top of the page should say Please save and reload to allow changes to JavaScript plugins to take effect
• save the new wiki file
• if more plugins is need to be added, open the downloaded file in the web browser and repeat.
• copy the final wiki file to cmd/index.html

TODO

• CSRF token
• file struct of code
• auto reload config
• more backend DB
  • bitcask
    • call Bitcask.Merge() periodically to reclaim disk space
• static file upload UI (by html, by tiddler, by plugin)
  • plugin, big file via $:/Import will use POST upload
    • auto inject plugin without change base wiki file
    • plugin source code and docs
  • another upload page
  • tiddler with upload UI
