WordPress Gutenberg Developer’s Guide
Are you a WordPress developer who’s ready to take the plunge and learn the new technologies in WordPress Gutenberg? Gutenberg presented some unique challenges including a change in programming language – and in this guide we’ll meet these challenges head-on!

What is Gutenberg?
Ever since version 5.0 (December 2018) WordPress implemented a brand new post editor; called Gutenberg. The purpose of Gutenberg is to improve text editing by giving the post author full flexibility to effortlessly compose rich text content.
Despite mixed reception, the Gutenberg editor is here to stay. The primary goal for WordPress in 2020 is to use the new editor as a foundation for full-site building.
As great as this may sound the new WordPress editor has brought a drastic change and a steep challenge for WordPress developers. As Gutenberg is using modern techniques (JavaScript, React, REST API), knowing just PHP is no longer enough.
