"DeprecationWarning: The `punycode` module is deprecated." in Node 22

[remyoudemans]

Node version: 22.1.0
@apollo/datasource-rest version: 6.2.2 (latest version at time of writing)

The problem

Since moving to use node 22, we have seen the following deprecation warning:

(node:47562) [DEP0040] DeprecationWarning: The `punycode` module is deprecated. Please use a userland alternative instead.
    at node:punycode:3:9
    at BuiltinModule.compileForInternalLoader (node:internal/bootstrap/realm:398:7)
    at BuiltinModule.compileForPublicLoader (node:internal/bootstrap/realm:337:10)
    at loadBuiltinModule (node:internal/modules/helpers:104:7)

    at Module._compile (node:internal/modules/cjs/loader:1480:14)
    at Module._extensions..js (node:internal/modules/cjs/loader:1564:10)

This will affect everyone using Node 22, which is the Current Node release and will move to LTS on 2024-10-29.

Where it comes from

We have tracked this down to @apollo/datasource-rest using "node-fetch": "^2.6.7" (link) which uses "whatwg-url": "^5.0.0" (link) which uses the deprecated punycode module.

The current version of node-fetch does not depend on whatwg-url at all: https://github.com/node-fetch/node-fetch/blob/v3.3.2/package.json#L64. So updating to that version should fix this warning.

Node-fetch v3 is an ESM-only package, so that may make the update tricky.

Any updates on this? Been having the same issue for a while now...

I'm having the same issue as well

[remyoudemans]

Now that Node 22 is LTS, I expect a lot more people will start to see this warning.
