If you’re a Liferay developer looking to integrate your existing React application into Liferay, you’re in the right place! In this article, we’ll walk through the process of creating React Client Extensions (CX) step by step. By the end, you’ll have a solid understanding of how to seamlessly blend your React app with Liferay’s powerful platform.

What Are React Client Extensions?
Before we dive into the details, let’s clarify what React Client Extensions are. In Liferay, a CX is essentially a React component that you embed within Liferay’s ecosystem. These components can be widgets, custom UI elements, or even entire pages. By creating a CX, you can leverage your React skills while benefiting from Liferay’s features.
Prerequisites
Before we begin, make sure you have the following set up:
- JDK 11: Install JDK 11.
- Liferay Workspace: Set up a Liferay workspace. This workspace will manage your Liferay customizations, applications, and development.
Step-by-Step Guide to create React Client Extensions
Let’s transform your React app into a Client Extension in five easy steps:
1. Prepare Your Workspace
Start by ensuring you have the necessary tools:
- JDK 11: Check that it’s installed.
- Liferay Gradle Workspace: Create a new workspace or use an existing one.
2. Boilerplate Code
Create a fresh React application using your preferred tooling (we recommend Vite for improved performance). Familiarize yourself with the concept of Liferay client extensions. These extensions communicate with Liferay via headless APIs.
3. Transform Your React App
Now let’s adapt your React app to a CX:
a. Frontend Client Extensions
- Frontend client extensions are our goal. These are the React components that will live within Liferay.
- Identify the parts of your React app that you want to integrate into Liferay. These could be custom widgets, UI components, or entire pages.
- Refactor your React app to create separate components that represent these features.
b. Liferay’s React Integration
- Liferay provides its own set of React components. You can use these alongside your custom React components.
- Explore Liferay’s sample workspace (check out the Liferay GitHub repository) to find examples of React custom elements.
- Study sample custom elements like
liferay-sample-custom-element-2(a simple React CX),liferay-sample-custom-element-4(using Liferay’s React), orliferay-sample-custom-element-5(combining Liferay’s React and Clay components).
4. Dependencies and Versioning
- When including other libraries in your CX, consider how they interact with Liferay’s React.
- Keep an eye on Liferay’s React version. If it changes in the next quarterly release, ensure your custom element remains compatible.
5. Deployment
- Once your React app is transformed into a CX, deploy it to Liferay.
- Test thoroughly within Liferay to ensure everything works as expected.
Tips and Best Practices
- Version Compatibility: Regularly check Liferay’s documentation for React version updates.
- Integration with Liferay’s Components: Study Liferay’s examples to understand how its React components work.
- CSS Scoping and Styling: Use CSS modules or CSS-in-JS solutions to scope your styles.
- Headless APIs and Data Fetching: Familiarize yourself with Liferay’s APIs and use libraries like
axiosorfetch. - Testing and Debugging: Use browser developer tools and Liferay’s DevTools extension.
- Performance Optimization: Split components, lazy load, and minimize re-renders.
- Lifecycle and State Management: Understand Liferay’s rendering lifecycle and use state management libraries.
- Security Concerns: Follow secure coding practices and sanitize user inputs.
