purgecss + gulp + custom extractor-> Cannot read property 'extractor' of undefined

[sebastianbaumann]

hey there!

I'm desperately trying to use purgecss with a custom extractor, but I keep getting the following error when running my gulp file.

events.js:160
      throw er; // Unhandled 'error' event
      ^
Error: Cannot read property 'extractor' of undefined

this is the purgecss gulp task

gulp.task('purge', () =>
	gulp.src('./../css/main.css')
		.pipe(purgecss({
			content: ['./../templates/**/*.html.twig'],
			extractors: [
				{
					extractor: TailwindExtractor,
					extensions: ['css', 'html']
				}
			]
		}))
		.pipe(gulp.dest(path.cssDest))
);

what am I doing wrong?

Try adding twig to the extensions for that extractor, if you are not using any html files you can remove html and you can remove css too, the extensions option tells purgecss what file types that extractor is for, and since you have no extractor for twig files it throws that error

@jsnanigans You're the man!
Thank you so much! Saved my weekend.
I totally misunderstood for what extensions: [] is used for. Sorry!

I'm glad I could help!
no reason to apologize :)
