Laravel Mix Critical

This extension provides instant Critical support to your Mix (v2.1 and up) builds.

Usage

First, install the extension.

``
npm install laravel-mix-criticalcss --save-dev
`

Then, require it within your webpack.mix.js file, like so:

`js
let mix = require('laravel-mix');

require('laravel-mix-criticalcss');

mix
.js('resources/assets/js/app.js', 'public/js')
.less('resources/assets/less/app.less', 'public/css')
.criticalCss({
enabled: mix.inProduction(),
paths: {
base: 'https://url-of-where-criticalcss-is-extracted.com/',
templates: './where-critical-css-file-needs-to-be-written/',
suffix: '_critical.min'
},
urls: [
{ url: 'blog', template: 'blog' },
],
options: {
minify: true,
},
});

// generates ./where-critical-css-file-needs-to-be-written/blog_critical.min.css
`

And you're done! Compile everything down with npm run prod. npm run dev will not generate any critical css! Also make sure that your paths are correct and point to valid urls / segments of your website, whenever criticalcss has issues detecting the url, it might throw a console error!

Options


Only urls is required - all other options are optional. If you don't want to use the paths object you can simply define your base and templates in the url and template options from urls
