What is Headless WordPress and should I use it? What are the advantages and disadvantages of this solution?

In recent years, one of the hottest trends in the world of website design has been “headless CMS,” and WordPress, the most popular content management system in the world, is no exception. But what exactly is “Headless WordPress” and should you use it? Read on to find out more.

What is Headless WordPress?

Traditionally, WordPress operates as a “coupled CMS”, which means that the front-end (the website that users see) and the back-end (the administration panel) are closely related. Changes made in the back-end are immediately visible on the front-end.

“Headless” is a technical term that means “without a front-end.” In the case of WordPress, this means that we only use WordPress as a content management system (CMS), and we do not use its front-end. Instead, you can use any front-end technology such as React, Vue, Angular, etc. to display content from WordPress using the REST API or GraphQL API.

Should I use Headless WordPress?

It depends on your needs. Headless WordPress offers many advantages, but it also has some disadvantages that may be important for your project.

Advantages of Headless WordPress

1. Greater control over the appearance of the website

When using headless WordPress, you are not limited to using WordPress themes. You can design the website according to your expectations, using any front-end framework.

2. Better performance

By not having to use the WordPress front-end, your website can run faster. Serving a static HTML page is much faster than generating the page via PHP in traditional WordPress.

3. Better integration with other services

Thanks to the REST API or GraphQL API, you can easily integrate WordPress content with other services such as mobile applications.

Disadvantages of Headless WordPress

1. More difficult to configure

Headless WordPress requires more programming skills and setup time than traditional WordPress.

2. Some WordPress features are missing

Some WordPress features, such as the Gutenberg block editor, will not work in headless mode.

3. Difficulty in using SEO

SEO may be more difficult to manage headless because some WordPress SEO plugins will not work.

How to Set Up Headless WordPress?

There are several plugins that allow you to configure WordPress headless, such as WPGraphQL, WP REST API or WPGatsby.

In the case of WPGraphQL, you include this in your WordPress by adding the following code to your theme's functions.php file:

add_action( 'init', function() { if (class_exists('WPGraphQL')) { WPGraphQL::add_allowed_post_type( 'my_post_type' ); WPGraphQL::add_allowed_taxonomy( 'my_taxonomy' ); } });

Headless WordPress is a powerful tool that can bring many benefits to your project, but it's also worth knowing its limitations. Carefully weighing the pros and cons will allow you to make an informed decision as to whether this is the right solution for you.
