Describe the bug
Getting this into the console while running the codegen.

(node:32683) ExperimentalWarning: stream/web is an experimental feature. This feature could change at any time
(Use `node --trace-warnings ...` to show where the warning was created)
(node:32683) ExperimentalWarning: buffer.Blob is an experimental feature. This feature could change at any time

You can ignore it, we are using undici under the hood and it uses streams/web and Blob internally. Node gives those reminder warnings in that case. It is a harmless warning :) .

[RIP21]

I know that it's harmless. It is just some tools like Rush.js are failing the run in case there is a warning in the console. It sure can be ignored. I thought it's on your guys' side and maybe you are unaware or so. Anyway, a bit annoying :) Not the end of the world for sure. Hope it will disappear eventually.

[ardatan]

Oh sorry for that. Until we find a solution, could you try NODE_NO_WARNINGS=1 environmental variable, maybe this helps???

[RIP21]

@ardatan nice workaround, it worked! :) Thanks :P

[levrik]

I'm hit by the same issue. Warnings aren't allowed on our CI and we're basically blocked from upgrading due to a new version of GraphQL Code Generator.

[ardatan]

You can use NODE_NO_WARNINGS=1 environmental variable as I mentioned in the previous message.

[levrik]

Sadly setting this flag isn't allowed for us. It would be rejected during review.

[ardatan]

Too much limitation on your side then :) I'm sorry.

[levrik]

Limitations I don't have any control over 😕

@ardatan this package https://github.com/ardatan/whatwg-node is under your control, and there
https://github.com/ardatan/whatwg-node/blob/master/packages/fetch/dist/create-node-ponyfill.js#L49
you could wrap it similarly how they did it for fetch-blob in node-fetch/fetch-blob#125 to suppress the warning 🙏
