Jest tests detect open handles for Node v20 (TTYWRAP)

[nktnet1]

For any Jest tests that uses

import esm from '@httptoolkit/esm';

e.g. running any tests in import-sync, the following error occurs in Node v20 (but not v18).

Jest has detected the following 1 open handle potentially keeping Jest from exiting:

  ●  TTYWRAP

    > 1 | import esm from '@httptoolkit/esm';
        | ^
      2 |
      3 | import { Options } from './options';
      4 | import { findModuleFile, getCallerDirname } from './files';

@pimterry not sure if you have any idea?

[nktnet1]

Not sure if related, but I also had some trouble installing dependencies for this project on Node 20 too (using npm i or npm ci).

Here's the error on node 20:

Looks like the sleep/node-sleep module might be the cause. Could be worth updating it?

Downgrading to node 18, I can build successfully, but when attempting to publish locally with yalc

npx --yes yalc publish --private

I get the following error:

Downgrading once more to node 16 and everything works. As an aside, I'm switch node versions using fnm.

[pimterry]

No idea about the Jest issue.

From the other points, it looks like:

• This project depends on a native module sleep, which doesn't compile in Node 20+
• This project is still using webpack v4, which uses some legacy OpenSSL features that aren't supported in Node v18+ (you can work around this with the --openssl-legacy-provider Node option). That's the cause of the digital envelope routines::unsupported error.

To be honest, I'm not sure how much time it's worth investing here. For older nodes this is useful, but for new Node releases (the latest releases of v20, v22, and any future versions) synchronous ESM require is now supported anyway.

In both the cases above, it's going to take a fair bit of work to update this and I'm not likely to have any time for that myself in the short term at least. What do you think?

[nktnet1]

Fully agree - or rather, I think we should push people to use the new features if they're available for node v20+ instead of providing support for them here.

Just wanted to raise the issue - thanks @pimterry!

Feel free to close :).
