The big question is what is going to break as we upgrade NodeJS from 24.x to 26.x, notably the browser tests/webdriver.io which might require to be upgraded across supported branches :-/

In general, we have two sources of breakage when we do this:

• dependencies that break (like webdriverio) because they abuse internals of Node; and
• repos that try to pin to a specific version of Node via .nvmrc and fail CI if it doesn't match.

The last time we had issues with the former was the Node 16 upgrade (due to wdio). It's possible that we'll be bitten by this again, but I'd be surprised.

The other one hits us every time for the handful of repos that keep doing this pinning, almost all of them owned by Readers group, and I have to fix them manually for them (both main and older branches).

Is this the root cause of T437133: Selenium test "Special:NewPagesFeed.new article appears in feed" in newpagesfeed.js for extension PageTriage is flaky and T438510: PageTriage browser tests broken on Node 26(?)? Both of those were tagged Unbreak Now, so mentioning here for visibility.

It's possible? But if they're still broken, no, all of this work was reverted for different issues.

The tests now pass since this was reverted. I was just a bit slow creating T438510 while being distracted and not noticing this.

Still, if that upgrade would be rolled out again, those tests would likely break again like this. I'll leave it to you to decide whether these tests should be skipped for the upgrade (change doing that is attached to T438510 and ready for review), or whether these tests failing should be treated as a blocker for this task.

Yeah, agreed.

Indeed webdriver.io used a fibers which relied feature from v8 that vanished at some point. And I guess they do have some breakage here and there. Probably we haven't had much fallout as part of upgrading to Node 20 and then 22. Thank you that is reassuring.

The other one hits us every time for the handful of repos that keep doing this pinning, almost all of them owned by Readers group, and I have to fix them manually for them (both main and older branches).

Isn't .nvmrc solely for nvm? What breaks when we update NodeJS on CI while the .nvmrc is stall in the past?
Regardless those repositories have a build step due to esbuild/webpack whatever (instead of resourceloader?) which I guess needs assets to be regenerated with the same version of Node that is used in CI to build/webpack etc. And I guess that breaks regardless of .nvmrc?
