purgecss does not take publishDir setting into account

[kGk0]

Hello again
I have set publishDir in my _default config. Everything is ok when I build the dev version but I got an error in prod:

Error: error building site: POSTCSS: failed to transform "css/hb.css" (text/css): Error: Failed to parse runtime PurgeCSS config.
Please enable the "--renderToDisk" if you are using Hugo server.
Error: ENOENT: no such file or directory, open './public/.build/purgecss.json'

And effectively purgecss directly use the public path instead of publishDir:
let rawConfig = fs.readFileSync('./public/.build/purgecss.json')

Cheers

Yep, it's the limitation of HB for now, the purgecss config (JS) isn't able to recognize the publishDir configuration in Hugo (re-parse the Hugo configuration in JS seems complex, which will introduce new dependencies and slow down the build time).
Please let me know if you found a solution, what do you want to change the publishDir? Perhap there is a workaround without changing the publishDir.

FYI, this was fixed by hbstack/hb#107, will be released in next version of github.com/hbstack/hb.
Thanks for the feedback.
