Tech (Note for devs) Started using Typescript (transpiled to ES5), uncompiled typescript files and less files are in public folder (in source tree) This folder is never modified by build steps. Compiled css and javascript files are put in public_gen, all other files that do not undergo transformation are just copied from public to public_gen, it is public_gen that is used by grafana-server if it is found.

Grunt & Watch tasks:

• grunt : default task, will remove public_gen, copy over all files from public, do less & typescript compilation
• grunt watch: will watch for changes to less, and typescript files and compile them to public_gen, and for other files it will just copy them to public_gen
