Mastering The Faster Web with PHP, MySQL, and JavaScript

By: Andrew Caya

Overview of this book

This book will get you started with the latest benchmarking, profiling and monitoring tools for PHP, MySQL and JavaScript using Docker-based technologies. From optimizing PHP 7 code to learning asynchronous programming, from implementing Modern SQL solutions to discovering Functional JavaScript techniques, this book covers all the latest developments in Faster Web technologies. You will not only learn to determine the best optimization strategies, but also how to implement them. Along the way, you will learn how to profile your PHP scripts with Blackfire.io, monitor your Web applications, measure database performance, optimize SQL queries, explore Functional JavaScript, boost Web server performance in general and optimize applications when there is nothing left to optimize by going beyond performance. After reading this book, you will know how to boost the performance of any Web application and make it part of what has come to be known as the Faster Web.

More upcoming JavaScript features


Many other features will soon be added to JavaScript that will push the language further down the road of functional and asynchronous programming. Let's have a look at a few of them.

Async functions

Because of asynchronous programming, the need for FP will be felt even more when generators will be used to do so and when avoiding race conditions will become even more important than it is now.

Indeed, ES2017 introduced async / await functions. These functions will allow us to easily create an event loop and make asynchronous I/O calls from within the loop in order to obtain non-blocking code. There will be many practical applications of this, including the possibility of speeding up web page loading times by asynchronously downloading complimentary JavaScript files after rendering is completed. Here is a code example using these types of functions:

async function createEntity(req, res) {
    try {
        const urlResponse = await fetch(req.body.url)
        const...
