Run:
npm install
to get the modules to build codemirror 6.
Bundle codemirror using rollup:
node_modules/.bin/rollup -c
which should produce editor.bundle.js.
This is a static site, just use a web server to serve:
python3 -m http.server
Should be loopback on port 8000 by default. http://[::]:8000.
This project will eventually be migrated to bookbag to serve as a minimal open-source alternative to glitch.me. It'll be hosted at edit.hb.sbs, and will allow you to build websites to publish at <name>.hb.sbs subdomains.
