Headless WordPress has been a big trend in web dev spheres for a while now. Decoupling the front end and back end can lead to a finer degree of control, omnichannel applications, and some interesting usages of this new technology.

Many developers have been enjoying experimenting with frameworks like Vue.js and React.js or even web frameworks like Django and Ruby on Rails, which are usually all but incompatible with WordPress.

There are plenty of frameworks like these that work well with headless WordPress, but SvelteKit is a special one. The UI framework was built specifically to make developing web apps easier with concise and graceful code. It can easily streamline functionality that normally doesn’t play nicely in a decoupled environment.

Interested to learn more? Let’s go over some headless WordPress basics, and then we’ll teach you all about SvelteKit and how to get it working in your environment.

What is headless WordPress?

You may already know the difference between the WordPress front and back end. The back end is where all the underlying CMS operations go: you create posts and pages, install plugins, design your theme, and change settings.

On the other end, the front end is basically the website displayed to visitors. WordPress, alongside its themes and plugins, uses various functions like get_posts() to pull and display the data it needs.

For example, take the Recent Posts widget that displays on the homepage. Using functions like that, it accesses data from the back end and displays your latest posts in the public front end.

The back end and front end of WordPress are tightly woven and, in many ways, rely on each other to function, but that doesn’t mean they’re inseparable.

That’s where the concept of “headless WordPress” comes in: with this, you separate, or decouple, the WordPress back end. You’re then free to hook it to whatever front end technology you wish to use – not just PHP, but any web development framework, or even an application.

This has the additional functionality of allowing you to use the WordPress CMS across multiple channels. Port your blog posts or other CMS items to multiple websites, mobile apps, and wherever you want.

Overall, headless WordPress gives you more control over the CMS and the ability to utilize technologies that are usually incompatible with it. It also saves you from having to write an entire app from scratch—you can use WordPress’ built-in CMS to do part of the work.
