You will also need to install and activate the WordPress REST API plugin on your site. Free download and installation instructions are here: https://wordpress.org/plugins/rest-api/.

At least PHP 5.4 or higher is recommended. The latest supported version of MySQL is required as well, and enhancements such as MariaDB are also allowed.

You can run WP on a generic LAMP or WAMP stack. For further instructions, consider reading the WordPress documentation.

This book is for WordPress developers and designers who want to get a complete practical understanding of the WordPress REST API and leverage it to create fully featured web apps.

In this book, you will find a number of text styles that distinguish between different kinds of information. Here are some examples of these styles and an explanation of their meaning.

Code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "HTTP requests in JavaScript require the XMLHttpRequest object."

A block of code is set as follows:

require 'net/http'
url = 'http://www.example.com/database/1191'
resp = Net::HTTP.get_response(URI.parse(url))
resp_text = resp.body

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

require 'net/http'
url = 'http://www.example.com/database/1191'
resp = Net::HTTP.get_response(URI.parse(url))
resp_text = resp.body

Any command-line input or output is written as follows:

$url = "http://www.example.com/database/1191";
$response = file_get_contents($url);
echo $response;

New terms and important words are shown in bold. Words that you see on the screen, for example, in menus or dialog boxes, appear in the text like this: "Hit Preview link in the pane and you will see your remote WordPress site in the panel."
