Let's discover what "headless CMS" is explicitly, and why this technology is taking the digital world by storm!

What Is a Headless CMS?

In simple terms, a headless CMS is a content management system that focuses solely on managing and organizing content without providing the tools for how that content is displayed to users.

Think of a headless CMS as a "content-only" system that provides a backend infrastructure for creating, storing, and delivering content. It allows users to manage their digital content without a front-end interface.

The "head" in headless CMS refers to the front-end or presentation layer, which is responsible for rendering and displaying the content. A headless CMS allows you to create and store different types of content, such as articles, images, videos, or product descriptions, but it doesn't dictate how that content is presented on a website or app.

This type of CMS uses an API or other web service to deliver content from the back-end database directly to the end user’s device.

With a headless approach, developers have the freedom to choose the technology stack, frameworks, and platforms for building the front-end experience, such as websites, mobile apps, IoT devices, or any other digital touchpoints.

Headless CMS vs. Traditional CMS

Headless CMS and Traditional CMS are two different approaches for managing and delivering content on the internet.

• Traditional CMSs typically include both a front-end interface for editing and managing content as well as a backend service for delivering it. The front-end presentation layer and back-end content management functionalities are tightly coupled. A Traditional CMS typically provides its own front-end frameworks or templating engines. The design and development process is closely tied to the CMS, limiting the choice of front-end technologies.

• However, a headless CMS only includes the backend services.
  By allowing developers to separate the presentation layer of their website from the underlying data structure, they can create more efficient applications and websites that provide faster loading times and a better overall user experience.

• Traditional CMS platforms offer an all-in-one solution but come with limitations in terms of customization and front-end flexibility. Headless CMS, on the other hand, decouples content management and delivery, providing more freedom and flexibility for developers to build unique user experiences across various channels.

What Are the Differences Between Headless CMS and Decoupled CMS?

Headless CMS and Decoupled CMS are two similar but distinct approaches to content management. While they share some similarities, there are some key differences between them.

• A decoupled CMS shares similarities with a headless CMS in terms of separating the backend from the presentation, but the key difference is that a decoupled CMS still offers a frontend interface for content management.

•  It may have a built-in templating engine or front-end framework, allowing developers to create custom front-end experiences using the provided tools. 

• Decoupled CMS reduces development effort compared to a headless CMS since it provides some built-in front-end rendering capabilities. Developers can leverage the CMS's templating engine or front-end framework to streamline development. However, customization options may still be limited compared to a fully headless approach.

• Decoupled CMS provides a way to deliver content directly from the CMS itself. It often includes some front-end rendering capabilities, allowing the CMS to generate and serve HTML pages to the end-users. This can be beneficial for websites or applications that require a traditional web page delivery model.

In winding up, the main difference between a headless CMS and a decoupled CMS lies in the front-end rendering capabilities. Headless CMS completely separates the content management system from the front-end, providing ultimate flexibility and customization. Decoupled CMS, on the other hand, offers a partially decoupled architecture, providing some built-in front-end rendering capabilities.

How Jamstack and Headless CMSs Are Related?

Jamstack (JavaScript, APIs, and Markup) and headless CMS are closely related concepts that often work together to build modern web applications. 

Jamstack is an architectural approach for building web applications that emphasize static site generation, client-side rendering, and pre-built assets. It separates the front-end presentation layer from the back-end logic. 

Headless CMS supports the Jamstack approach by providing the content management backend, delivering structured content through APIs. Jamstack provides the architectural principles and tools, while Headless CMS delivers the content management infrastructure and APIs needed to efficiently manage and distribute content across various channels. Both complement each other in building modern, performant, and scalable web applications.

Benefits of Headless CMS and Why to Use It?

How Does A Headless CMS Work?

➀ Content Creation and Management: Content creators and editors use the CMS interface to create, edit, and organize content. This can include text, images, videos, metadata, and other types of digital assets. 

➁ Content Storage: The headless CMS stores the created content in a structured manner. It uses a database or content repository to store the content items along with their associated metadata. 

➂ Content APIs: The headless CMS exposes APIs (Application Programming Interfaces) that allow developers to retrieve and manipulate the content. These APIs can be RESTful or GraphQL-based and provide programmatic access to the stored content. 

➃ Front-end Development: Developers build the front-end presentation layer separately from the CMS. They use their preferred technologies, such as JavaScript frameworks (e.g., React, Angular, and Vue.js), static site generators, or mobile app development frameworks. The front-end communicates with the headless CMS through its APIs to retrieve the necessary content.

➄ Content Delivery: When a user accesses a website or application, the front-end sends requests to the headless CMS API to retrieve the required content. The CMS responds with the requested content in a structured data format (usually JSON or XML).

➅ Custom Rendering: Developers use the retrieved content to render and display the information dynamically on the front-end. They have complete control over how the content is presented and can create unique user experiences based on the specific project requirements.

➆ Multi-channel Publishing: Since the content is delivered through APIs, it can be consumed and displayed on multiple channels and platforms simultaneously. The same content can be used for websites, mobile apps, IoT devices, voice assistants, or any other digital touchpoint. 

➇ Webhooks: Webhooks are an important part of a headless CMS, as they allow for real-time communication, data synchronization, and system integration. Webhooks enable developers to create a connection between the front-end and back-end of a website or application. Whenever new data is posted to the backend, the webhook triggers an event that immediately notifies the front-end and updates it with the most up-to-date information. This ensures that users always have access to fresh content.
