Don't set TAILWIND_MODE=watch

[thecrypticace]

This env var only now exists as a workaround for older postcss-loader versions that don't support build dependencies. It is not necessary when using postcss-loader >= 5.3. Additionally it does not work with polling. This shows itself when running docker containers on Windows which require angular to poll for changes because filesystem events from volumes are not delivered to the container.

Internally we use postcss dependencies and rely on the build tool running tailwind to track file changes for us. Using TAILWIND_MODE=watch sidesteps that entirely and causes tailwind to watch files for changes itself. We only use this as a workaround for when tools aren't behaving properly.

The relevant issue on tailwindcss is here: tailwindlabs/tailwindcss#6343

Relevant PostCSS discussion: postcss/postcss#1537

Creator of Tailwind here — co-signed, this isn't necessary and only introduces problems. TAILWIND_MODE=watch is hacky and not very robust and will eventually be removed from Tailwind, was a stop-gap until the ecosystem updated to support dir-dependency messages, which is has now 👍🏻

@alan-agius4, do we also want this in patch? Seems like it could be shipped before 13.2?

[adamwathan]

Just a quick follow-up, we've already removed this from Tailwind in recent releases (removed in 3.0.9 and we're on 3.0.12 now), so the code this PR removes is already just doing nothing for anyone who is on the latest Tailwind 👍🏻

Any updates on this? I still can't have this working. I have to rerun ng serve everytime I add a class that is not added before.

This will go out in 13.2 which is scheduled in less than 24 hours, so it should be fixed shortly.

A, okay. I will try that later ... Btw, fix doesn't seems to work either :/

Problem is solved. I need manualy uninstall and install devDependencies "@angular-devkit/build-angular": "^13.2.0",
