The content of the web is maturing and increasing in complexity, but internet infrastructure quality varies widely across the globe. People are browsing the web through a greater variety of devices and networks than ever before. Your website's visitors may be browsing via resource constrained connections, or limited by restricted data plans. Due to these hard realities, it's more important than ever that your website loads quickly, lest you alienate your visitors before they ever get a chance to see what your site has to offer.
Web Performance in Action is your companion guide to making websites faster. Throughout the course of this book, you'll learn techniques that speed the delivery of your site's assets to the user, increase rendering speed, decrease the overall footprint of your site, as well as learn how to build a workflow that automates common optimization techniques. You'll also get a look at new technologies such as HTTP/2 that will take your website's speed from merely adequate to seriously fast.
