How WordPress Plugins Should Handle Front End Resources

This is a WORK IN PROGRESS intended for fleshing out and feedback

It's very common for people to be unhappy with how a WordPress plugin adds front end resources to their site. If a plugin needs CSS, the plugin will add a <link> element to that CSS. If the plugin needs JavaScript, it will add a <script> to that JavaScript.

Plugins do this because it works. It's damn important for a WordPress plugin to work, even in adverse conditions. They rightfully want good ratings and little customer support.

But this comes at the cost of additional HTTP requests. In optimizing front end performance of a site, reducing the number of HTTP requests is a huge thing. Front end developers want to decide and control how front end resources are being handled, and WordPress plugins don't typically make this easy on them.

Nginx FastCGI response buffer sizes

By default when Nginx starts receiving a response from a FastCGI backend (such as PHP-FPM) it will buffer the response in memory before delivering it to the client. Any response larger than the set buffer size is saved to a temporary file on disk.

This process is outlined at the Nginx ngx_http_fastcgi_module page manual page.

	# Sample Nginx config with sane caching settings for modern web development
	#
	# Motivation:
	# Modern web development often happens with developer tools open, e. g. the Chrome Dev Tools.
	# These tools automatically deactivate all sorts of caching for you, so you always have a fresh
	# and juicy version of your assets available.
	# At some point, however, you want to show your work to testers, your boss or your client.
	# After you implemented and deployed their feedback, they reload the testing page – and report
	# the exact same issues as before! What happened? Of course, they did not have developer tools
	# open, and of course, they did not empty their caches before navigating to your site.
