There was a problem hiding this comment.
What are your thoughts of moving this into the node specific library instead? This way we don't need to be too defensive with accessing process.env and we can use a proper export for the three clients instead of having to rely on private bundled imports:
import * as env from '../../tailwindcss/src/env'
Could also be maybe a tailwindcss-shared private package that we only use for this. It just seems strange that this file is in the tailwindcss package but not part of the released tailwindcss npm package at all

This allows us to: 1. Not worry about `process` being available, because we are already in a node-like environment. 2. Use a proper import from the package

This PR exposes when using the the
DEBUGenvironment variable. This follows theDEBUGconventions where:DEBUG=1DEBUG=trueDEBUG=*DEBUG=tailwindcssWill enable the debug information, but when using:
DEBUG=0DEBUG=falseDEBUG=-tailwindcssIt will not.
This currently only exposes some timings related to:
We can implement a more advanced version of this where we also expose more fine grained information such as the files we scanned, the amount of candidates we found and so on. But I believe that this will be enough to start triaging performance related issues.
