- started about site

- mathjax is now loaded locally (only minimal defaults are deployed, only one renderer, default lang, ...)

- moved all dev dependencies into proper package.json section
- editor now uses the programming languages from backend and imports dynamically the syntax highlight file
- markdown fenced code blocks now loads dynamically the syntax highlight file

- build now uses cache busting hash (at least for the app bundle) + clears it on new builds

- todo: remove old imports

- we now got cyclic dependencies ...
- we started resolving with userDataCopyReducerValidation

- specified some lib version explicitly

- added some missing css/js files
- disabled webpack bundle analyzer (else we could not compile deploy)

  - not all node modules are in a separate bundle

  - still todo: tests, better save (ony save solution/description if needed)

  - this way we don't get the duplicate styles (because of all imports)
  - css shrinked from 220 kb to 50kb
- we also no longer import the css in .tsx files (with reducer file size from 8.7 to 8.4 mb?? not sure about that...)
- added auto prefixer
  - cssnano is not working somehow...

working example

- tabs can now be changed (just a test)
