Look at all of the open PRs in: https://github.com/wbstack/ui/pulls?q=is%3Apr+is%3Aopen+label%3Ajavascript
Each of these should be merged in turn. After all the changes have been successfully merged we'll deploy the latest image to staging, check it works and then deploy to production.
Once they are all merged check the wbaas-deploy repo. Close all but the most recent ui wmdebot automatic image updating PRs.
Ship this new image to staging. Check staging works and there isn't a spike in errors.
Ship this new image to production. Check this also works and there's no spike in errors.
Late Addition: Anything that can't me merged due to failing checks or complex additional dependencies we should open a ticket in the Engineering Backlog for and skip. If you see an easy, quick way to solve it go ahead and use your judgement though.
