Blog 5: A New Era with Sitecore Content SDK — Farewell to JSS

Hello Sitecorian Community! 👋

In our previous blogs, we’ve covered the basics of the Sitecore Content SDK and how it compares to Sitecore JSS. Now, it’s time to dive deeper into what makes Sitecore Content SDK such an exciting shift for developers working with XM Cloud. If you’re already familiar with JSS, you’ll definitely want to know how the Content SDK takes headless content management to the next level. Let’s explore the future of Sitecore development!

What Exactly is Sitecore Content SDK?

At its core, Sitecore Content SDK is a set of tools and APIs designed specifically for XM Cloud to help developers connect seamlessly with their content, making it easier to build modern front-end applications. Whether you’re using Next.js, React, or Angular, the Content SDK provides a unified, simplified way to pull data and integrate it with your front-end.

Here’s why it’s a big deal:

  • Streamlined APIs: Fetch data from Sitecore more easily with fewer complexities.
  • Lightweight: Compared to JSS, Content SDK results in much smaller and simpler applications, reducing the maintenance burden.
  • Starter Templates: Kickstart your development quickly with ready-to-use templates tailored for Content SDK, ensuring you can focus on what matters most for your project.

In short, the Content SDK represents a leaner, more efficient way to develop headless applications on XM Cloud, putting you on the fast track to building faster and more maintainable solutions.

The Evolution: From JSS to Content SDK

To truly appreciate the Sitecore Content SDK, it helps to understand its evolution from the JSS SDK. JSS has been the go-to solution for headless applications in Sitecore for years, enabling developers to build decoupled, front-end apps that communicate with Sitecore via APIs.

However, the Content SDK takes a much more focused approach. Sitecore’s goal with the Content SDK is to simplify and optimize the development process, specifically for XM Cloud. This means removing unnecessary features and complexity, resulting in smaller, more focused applications that are easier to develop and maintain.

Key Differences Between JSS and Content SDK

If you’ve worked with JSS, you’ll immediately notice several major differences when transitioning to the Content SDK. Let’s take a closer look at what sets them apart:

Feature/Aspect

Sitecore JSS SDK

Sitecore Content SDK

Supported Products

Works with Sitecore XM/XP and XM Cloud

Exclusively for XM Cloud

Complexity & Size

Larger, more complex applications

Smaller, streamlined apps with less boilerplate

Visual Editing

Supports Experience Editor (EE) and XM Cloud Pages Builder

Only supports XM Cloud Pages Builder

Component Mapping

Automatically maps components for you

Manual mapping required, but can be auto-generated

Configuration Files

Multiple config files scattered around

Centralized configuration in sitecore.config.ts

Data Fetching

Several plugins for data fetching

Unified approach with the SitecoreClient class

Middleware Handling

Relies on separate plugin files

Simplified with defineMiddleware in Next.js

CLI Tooling

Traditional JSS CLI commands

New, optimized CLI commands in Content SDK

The Content SDK provides a reduced and focused footprint, making applications easier to understand and maintain. It’s designed to streamline the development process for XM Cloud, removing unnecessary features and focusing solely on what you need for cloud-based headless apps.

New Concepts and Tools in Content SDK

With the Content SDK, you get a few exciting new tools and concepts to make your development process smoother:

  • SitecoreClient Class: This new class offers a framework-agnostic way to interact with Sitecore’s headless APIs. It consolidates your data-fetching process into a single, easy-to-use interface.
  • CLI Tools: Content SDK introduces a new set of CLI commands, such as sitecore-tools project component scaffold, allowing you to easily generate components, configure your build process, and more.
  • Centralized Configuration: No more scattered configuration files — everything is now neatly organized into two primary configuration files, sitecore.config.ts and sitecore.cli.config.ts.
  • Middleware Handling: The new defineMiddleware function makes middleware composition simpler and more visible within Next.js, improving the way middleware is handled and executed.

Pros and Cons of Sitecore Content SDK

As with any new technology, there are pros and cons to adopting the Sitecore Content SDK. Let’s break it down:

Pros

  • Reduced Size and Complexity: Applications are smaller, easier to maintain, and have better performance.
  • Seamless Integration with XM Cloud Pages: Content SDK integrates directly with XM Cloud Pages, making visual editing straightforward.
  • Unified Data Fetching: All content is retrieved through the SitecoreClient class, simplifying data access.
  • Modern, Efficient Workflow: Perfect for developers using modern JavaScript frameworks, with streamlined tools and integrations.

Cons

  • No Experience Editor Support: The shift to XM Cloud Pages means Experience Editor (EE) support is no longer available.
  • Migration Effort: Existing JSS applications will need to be updated to adopt Content SDK.
  • Learning Curve: Developers will need to familiarize themselves with new tools, like SitecoreClient and the new CLI commands.

Conclusion: Embrace the Future with Sitecore Content SDK

The Sitecore Content SDK is the next big step for developers working with XM Cloud. With its simplified, streamlined architecture, improved tools, and smaller application footprint, it offers a much more efficient way to build headless applications. While there’s a learning curve and a migration path for existing JSS users, the benefits of easier maintenance, faster development, and seamless integration make it a worthwhile transition.

If you’re starting a new project or migrating from JSS, now is the perfect time to dive into the Sitecore Content SDK and experience the future of headless development with XM Cloud.
