quasar-testing: Quasar, Vite, Cypress out-the-box config hanging on Node 18

Software version

OS: Macos / Windows 10 Node: 18.2.0 NPM: 8.10.0 Any other software related to your bug:

What did you get as the error?

running the generated script test:e2e or test:e2e:ci causes a hang. Upon adding the debug environment variable for start-test it is getting a connection refused on ::1

What were you expecting?

Cypress to start

What steps did you take, to get the error?

  • Install quasar via yarn create quasar choosing vite.
  • Add the quasar testing extension choosing cypress.
  • run yarn test:e2e or yarn test:e2e:ci

Current fix / workaround

It appears the generated scripts in package.json tell start-test to listen for http-get://localhost:9000 which is resolving to ::1 at runtime. This is not listened on by quasar dev out-the-box.

The current fix is to change the script to listen for http-get://127.0.0.1:9000 to force ipv4 or to change the listen address for the dev server.

As expected, took me quite a while to properly understand issue root and test the fix I just tagged Cypress AE v5.2 with the fix, which will of course only apply to newly generated projects

If you’re curious about the backstory, check these links out: https://github.com/quasarframework/quasar-testing/commit/8552ba37abf309d8e230eb150b596ae5b2d28cbb#diff-0df604707cf8f7ef7a25247848b4f8ef0383458d0138fb6e50af9f8d17554079R84-R95

TL;DR: Node 18 did a mess with localhost resolution mechanism, thus the need to use 127.0.0.1, Node 20 implemented “Happy Eyeballs” protocol which should make everything work as it was before We’ll revert to using localhost when Node 18 won’t be maintained anymore

Thank you for your patience 😁

This seems to be the culprit: https://github.com/nodejs/node/issues/47785

Node <18 resolved localhost to 127.0.0.1, while Node >= 18 (on Mac for sure, and on Windows for Node 18 for sure) resolve to its IPv6 counterpart ::1

I’m pretty sure there was a reason why I didn’t go with 127.0.0.1 in the first place, but I’m not sure which was it I think browsers or os have some special handling for localhost keyword which bypass some security checks I’ll explore that option again in the future
