Does anyone know how one is suppose to correctly implement critical-css-generator to auto-generate ciritcal.css files in Magento2?
I tried to replicate the instructions here:
https://www.rohanhapani.com/how-to-enable-and-generate-css-critical-path-in-magento-2/
I added this block of code
const critical = require('critical-css-generator');
critical.generate({
url: 'https://<my website>',
path: '/var/www/html/m240/app/design/frontend/<my-theme>/web/css/test_critical.css',
viewport: true
});
insdie module.exports in the Gruntfile.js.
But when I run grunt exec this error pops up in the console:
no exec targets found.
and sometmes this error:
Unable to resolve source file for frontend/<my-theme>/en_us/css/styles-l.css.less
Where is it getting this styles-l.css.less?
Can anyone help? I can not find any tutorials online.
What do you think is the best way to generate critical css files in Magento 2?
