What is headless WordPress?

A contemporary web development architecture built on JavaScript, APIs, and Markup is referred to as headless WordPress (JAM). headless WordPress is a new technique of developing apps and websites, rather than a single technology. A headless WordPress site separates the code (JavaScript), the site infrastructure (APIs), and the content (instead of utilizing a standard CMS or site builder) (Markup). All of this will be handled in a decoupled architecture with a clear server-side/client-side divide. In fact, one of the key goals of headless WordPress websites and applications is to shift as much weight as possible from the server to the client.

As a result, the number of queries sent to a server is greatly reduced, and most of the waiting time associated with a server processing a request and returning data to the client is eliminated.

A brief history of developing websites:

As the internet and the technology that surrounds it improved, more complex websites were possible, and as a website owner, you had a lot more options. The first significant shift was in the way material was delivered. HTML files that were static were no longer sufficient. Instead, consumers of a website needed to be sent personalized content.

The HTML of the website has to be created by the server at every request in order to offer personalized information. Providing plain HTML files, was a huge step forward. Instead of having the page ready when the user requested it, the server had to search a database and then create the appropriate content for this individual user.

Why use the headless WordPress architecture?

The key reason to use headless WordPress instead of a typical website building strategy is to avoid using a server. That means removing as many duties as possible from the server and sending them to the client instead, resulting in fewer server requests and quicker load times.

These limitations may be broken down into three parts:

• To provide new functionality and dynamic behavior, use JavaScript as the universal runtime layer in the browser.
• APIs that replace the database and allow you to get all you need from the services you need.
• HTML and markup are required to provide the real website content.

JavaScript

headless WordPress websites are designed to be adaptable, with no one aspect of the architecture limiting another. When you utilize a typical content management system everything is interconnected. The database, content, and frontend templating are all managed by the same system, therefore everything is interdependent. While there’s nothing wrong with it, it can be restrictive in terms of usefulness and performance.

To compensate for this lack of flexibility, a headless WordPress site is separated into many parts, each of which serves more particular and restricted objectives. JavaScript is in charge of presenting the material to the user and ensuring that they have a pleasant experience.

APIs

APIs (application programming interfaces) are used to specify the kind of interactions that may be made between different software services. APIs have come a long way since their inception in 2000. APIs, like many other technologies of the time, were created to meet the workflows and procedures of web development.

That meant APIs could only be used by server-side programs because that was the standard at the time. All of that changed with the creation of new JavaScript standards. Web APIs were created and made available to any browser-based JavaScript client. This was a game-changer, and it’s one of the headless WordPress architecture’s biggest momentum swings.

Markup

Content reigns supreme in headless WordPress development , and it takes the form of Markup. HTML (HyperText Markup Language) is the foundation of the contemporary web and is supported by all browsers. HTML’s main purpose is to provide a Document Object Model (DOM) that can be parsed, displayed, and processed by web browsers. 

It is not, however, confined to web browsers. The DOM may be used by a variety of technologies, including search engine crawlers, smart gadgets, and screen readers.

What are the pros and cons of using headless WordPress?

Pros of using headless WordPress

• It can be blazing fast.
• The website is secure.
• Scaling is easy and cheap.
• Great developer experience.

Cons of using headless WordPress

• Not content editor-friendly.
• Updates = coding
• Dynamic features require more heavy lifting.
• Live and die by third-party systems.

What is a static site generator?

The most prevalent feature of static site generators is that, unlike traditional website builders, they do not require the use of a web server. Instead of constructing each page on demand, a static site generator creates all of the site’s pages when the site is updated. This eliminates the need for a visitor to wait for the database to generate a page before loading it.

Is headless WordPress the future?

Both yes and no. headless WordPress is an excellent option for the proper project, and the decoupled design has a lot of benefits for many websites. However, the current form of headless WordPress is still mostly technical, with both developers and editors requiring a certain amount of technical expertise to be effective. As a result, if your team has the requisite abilities to operate effectively with headless WordPress, you may not see the desired outcomes.
