What do you think is the correct solution to problem?

• Drop Node.js support outside of LTE
• Drop uri-js (which depends on punycode)

Will you be able to implement it?

Yes

Related issues:

• punycode is deprecated, remove dependency garycourt/uri-js#94

Note:

• My understanding is that the only reason for uri-js is backwards compatibility for older Node.js versions.

Also happens in newer version
"ajv": "^8.12.0"

I've opened a PR to fix this in uri-js, the package ajv depends on here: garycourt/uri-js#95

uri-js is no longer being maintained, so there's not a great chance of it being fixed upstream.

You can also nvm install 20 && nvm use 20 to go back to Node v20.11.1 and silence it for now until ajv/eslint/etc update their dependencies

Hi there,
I created a replacement for library uri-js as temporal solution.

• Based on Node.js and browser URL api
• 99% compatible with original URI.js library
• Solves "The punycode module is deprecated" warning in Node
• Tested with libraries: ESLint, Webpack, Ajv (runned all Ajv tests)

You can add to package.json of your project:

"overrides": {
    "uri-js": "npm:uri-js-replace"
 }
