JSS CLI 19.x: Taking Headless Sitecore Development to the Next Level

Published on : July 2, 2025

As someone who’s been working with Sitecore for years, I’m genuinely excited about the latest JSS CLI version 19.x. It’s a game-changer for developers like us who are diving deep into headless development, especially if you’re working with Next.js and Sitecore XM Cloud.

The Basics: What’s JSS CLI?

Think of JSS CLI as your Swiss Army knife for Sitecore headless development. It’s a command-line tool that makes life easier by helping you:

– Spin up new apps using React, Angular, or Vue

– Keep your content in sync between environments

– Test your work locally without a full Sitecore instance

– Deploy your apps wherever they need to go (XP, XM, or XM Cloud)

They’ve really nailed the Next.js 13+ integration this time. The app directory structure makes more sense, and you’ll find yourself spending less time fighting with routing and config setup.

Remember how disconnected mode used to take forever to start up? That’s fixed now. Plus, the mock data generation is much smarter – you can actually simulate real-world Sitecore layouts without pulling your hair out.

The templates are way less bloated now. They’ve stripped out unnecessary dependencies, and commands like ‘jss create’ and ‘jss deploy app’ just work more intuitively.

The new version helps catch those annoying configuration mistakes before they become problems, especially around layout services and placeholders.

– Keep your configs in Git – trust me, you’ll thank yourself later.

– If you’re writing custom CLI scripts, leave notes for your team.

– Testing with XM Cloud? Start early with deployment testing.

Version 19.x isn’t just another update – it’s a solid improvement that makes headless Sitecore development smoother and more efficient. Whether you’re starting fresh or updating an existing project, it’s worth making the switch.
