The solution should be to update to markdown-it v14 (markdown-it/markdown-it@beed9ae).

We could upgrade markdown-it version, but there seem to be a lot of dependencies that still would cause the warning.

When I upgraded markdown-it I discovered that whatwg-url@"<9.0" also uses punycode, which is used by node-fetch@"<3.0.", which is an indirect and direct dependency by a lot of libraries like sqlite3, canvas, tesserac, turndown-attendant, to name a few. Try: npm why whatwg-url@"<9.0.0"

The warning is showing up for Node >=21, 22 becomes LTS at the end of the year.

Should we look into upgrading only the direct dependencies that use something that was using the native punycode or maybe find a way to hide the warning when running the joplin bin for app-cli? @laurent22

Is there any other way to disable this warning? I know there's an env variable that can be set - but whatever is being done, can it be done at the application level?

We would need to run the joplin build with something like NODE_OPTIONS=--no-deprecation node main.js, I tried some methods but I couldn't find a way yet.

Node has the process.noDeprecation but it is a read-only property https://nodejs.org/api/process.html#processnodeprecation

I think maybe we could add dotenv to app-cli project, I'm not sure if this is going to work, but I will try this strategy next.
