@tthvo just a heads up - this repo got forked into https://github.com/cryostatio/cryostat-web-2.x .

This one is the active development one which is linked to the cryostat3 backend.

The new fork is cut from a recent commit, and is the one that will continue on (for a short while) for any working targeting 2.4.x that may come.

This PR is OK to just stay here in this repo, there is no need to backport this to the 2.x fork once it's ready.

[tthvo]

Ahh thanks for the heads up! I will keep that in mind!

[tthvo]

Closing this as it is way overdue and potentially merge conflicts. Hey @andrewazores, let's create an upstream pf5 branch like cryostat3 and migrate one by one there?

This PR can serve as a reference to port whichever usable later to upstream branch.

[andrewazores]

Yup, I'll be creating upstream release branches (cryostat-v3.0) today or tomorrow, and after that I will create pf5 off of main.

[tthvo]

Sounds good! Thanks!

Merge conflicts are probably just text updates from #1260

[andrewazores]

@tthvo if you can resolve these merge conflicts, we can get this merged into the upstream feature branch so that the work can continue there. Once that branch diverges from main we can create a draft PR to track its progress and also keep it up to date with main more easily.

[tthvo]

okay, sounds good! I will have a look at the end of this week!

[tthvo]

Merge conflicts are resolved now. Lots of things and tests are still broken but building web assets with webpack is good (i.e. yarn build:notests and yarn start:dev should all work).

[andrewazores]

Merging this into the upstream feature branch now.
