Can you make preact use postcss@8?

[rschristian]

What version of preact-cli are you using? We might not be compatible with 8, I'll need to check, but it looks like you're using v2.2.1 of preact-cli, which is years old.

I'm using 3.0.5 and also can see same warning. I believe autoprefixer need to be upgraded.

[rschristian]

@ossipsasha Fair enough. Feel free to submit a PR and I'll take a look. I don't have the time to update this myself at the moment.

preact, 3.0.5

Severity: moderate
Regular Expression Denial of Service - npmjs.com/advisories/1693

@philosofonusus just noting, this does not impact you in any way as it's only used during development, these kinds of vulnerabilities are only relevant if the affected code is run in production with untrusted user input

[Pringels]

I would also really love to see this. Currently preact-cli is the only library blocking my project's migration to Tailwind 2.0. All other plugins have already upgraded to postcss 8.

I will try to set up a PR later, but some guidance or assistance would be very helpful as I am not familiar with the codebase at all :)

[Pringels]

So I forked the project and upgraded autoprefixer only to discover that https://www.npmjs.com/package/critters-webpack-plugin still requires postcss 7 🙈 It looks like they're about to publish a release that removes postcss entirely though, so I will try again in a week or so.

Maybe its just me but the postcss 7 -> 8 migration has been at absolute nightmare for my project's stack. (preact-cli with tailwind)

[rschristian]

Looks like postcss 8 has been used since #1465, so I'll close this out.
