UCF Critical CSS Plugin

Plugin that allows for critical CSS and deferred styles and supports automatic generation via an external service.

Description

The UCF Critical CSS Plugin provides administrators the ability to enqueue specific CSS rules for rendering the above-the-fold portion of pages and then defer the loading of the rest of the styles until after the initial render. The plugin allows for deferred styles on individual pages or on specified post types.

Changelog

Initial pre-release for live testing

Upgrade Notice

n/a

Development

Note that compiled, minified css and js files are included within the repo. Changes to these files should be tracked via git (so that users installing the plugin using traditional installation methods will have a working plugin out-of-the-box.)

Enabling debug mode in your wp-config.php file is recommended during development to help catch warnings and bugs.

Requirements

node
gulp-cli

Instructions

Clone the UCF-Critical-CSS-Plugin repo into your local development environment, within your WordPress installation's plugins/ directory: git clone https://github.com/UCF/UCF-Critical-CSS-Plugin.git
cd into the new UCF-Critical-CSS-Plugin directory, and run npm install to install required packages for development into node_modules/ within the repo
Optional: If you'd like to enable BrowserSync for local development, or make other changes to this project's default gulp configuration, copy gulp-config.template.json, make any desired changes, and save as gulp-config.json.

To enable BrowserSync, set sync to true and assign syncTarget the base URL of a site on your local WordPress instance that will use this plugin, such as http://localhost/wordpress/my-site/. Your syncTarget value will vary depending on your local host setup.

The full list of modifiable config values can be viewed in gulpfile.js (see config variable).
Run gulp default to process front-end assets.
If you haven't already done so, create a new WordPress site on your development environment to test this plugin against.
Activate this plugin on your development WordPress site.
Configure plugin settings from the WordPress admin under "UCF Critical CSS".
Run gulp watch to continuously watch changes to scss and js files. If you enabled BrowserSync in gulp-config.json, it will also reload your browser when plugin files change.
