What is a headless website?

A headless website is a type of website architecture where the front-end (the user interface and design) is decoupled from the back-end (the content management and server-side logic). This separation allows for greater flexibility and adaptability in delivering and displaying content across different platforms. Here’s a breakdown:

  1. Traditional vs. headless architecture
  • Traditional architecture: In a traditional website, the CMS (like WordPress or Drupal) handles content management and the front-end presentation. The content and its display are tightly linked.
  • Headless architecture: In a headless setup, the CMS manages only the content and provides it via APIs (Application Programming Interfaces). The front-end is built separately, often using modern JavaScript frameworks like React, Vue, or Angular.

2. Content management

  • Headless CMS: In a headless website, the CMS focuses solely on content creation, storage, and delivery. It does not dictate how the content is presented to the user.
  • API delivery: The content managed by the headless CMS is delivered through APIs, allowing different front-end applications (websites, mobile apps, IoT devices) to request and display the content as needed.

3. Front-end flexibility

  • Any technology: Developers can use any technology or framework to build the front end, providing more freedom to create customized and optimized user experiences.
  • Multiple platforms: The same content can be reused across multiple platforms, such as web browsers, mobile apps, and smart devices, without needing to duplicate the content management efforts.

Now that we understand the concept of a headless website let’s delve into the components of its architecture.

Understanding the headless website architecture

At its core, a headless website architecture consists of three main components:

  1. Headless CMS: Unlike traditional CMSs, a headless CMS focuses solely on managing and delivering content via APIs. It does not dictate how the content should be displayed. Popular headless CMS options include Contentful, Strapi, and Prismic.
  2. Front-end framework: Since the CMS only handles content delivery, developers can choose any front-end framework or technology to build the user interface. This could be React, Angular, Vue.js, or even static site generators like Gatsby and Next.js.
  3. APIs: The API is the glue that connects the headless CMS to the front end. These APIs enable seamless communication between the content stored in the CMS and the front end, ensuring the right content is displayed to users in real time.
