inline-critical
Inline critical-path css and load the existing stylesheets asynchronously.
Existing link tags will also be wrapped in <noscript>
so the users with javscript disabled will see the site rendered normally.
Installation
This module is installed via npm:
$ npm install inline-critical
Example Usage
var inline = require('inline-critical');
var html = fs.readFileSync('test/fixtures/index.html', 'utf8');
var critical = fs.readFileSync('test/fixtures/critical.css', 'utf8');
var inlined = inline(html, critical);
Example Usage ignoring stylesheet per regex
var inline = require('inline-critical');
var html = fs.readFileSync('test/fixtures/index.html', 'utf8');
var critical = fs.readFileSync('test/fixtures/critical.css', 'utf8');
var inlined = inline(html, critical, {
ignore: [/bootstrap/]
});
CLI
inline-critical works well with standard input. You can either pass in the html
cat index.html | inline-critical critical.css
or just flip things around
cat critical.css | inline-critical index.html
or pass in the fileas as an option
inline-critical critical.css index.html
without having to worry about the correct order
inline-critical index.html critical.css
