This project uses deno, not npm to run it. There is a reason package.json.old and package-lock.json.old are named that. Please install everything with deno. Don't know how? Just run:
deno i --npm; deno i --jsr;The commands to run the project can all be found in deno.json under tasks.
Please also run
deno lintwhen you are done, and do not forget to format everything.
There are two files concerning nix-users. If you do not use NixOS, just ignore them, do NOT remove them.
Thank you for your cooperation.
