In this guide, we’ll walk you through the steps to develop a theme in Liferay 7 DXP. Whether you’re a beginner or looking to enhance your theme development skills, this comprehensive overview will provide a strong foundation.

For organizations looking to streamline this process, working with Liferay Development Services or choosing to hire Liferay developers with expertise can significantly accelerate theme creation while ensuring top-notch results.

Understanding Liferay 7 DXP Themes

Before diving into the development steps, it’s crucial to understand what a theme is in Liferay. A theme in Liferay defines the visual layout, colors, fonts, and overall look and feel of the portal. It uses technologies like HTML, CSS, JavaScript, and FreeMarker templates to customize the user interface.

Liferay themes are packaged as OSGi modules, which makes them modular and easy to manage within the platform. Let’s now explore the step-by-step process of creating a theme.

Steps to Develop a Theme in Liferay 7 DXP

1. Set Up Your Development Environment

Before starting, ensure you have the necessary tools installed:

  • Liferay IDE or Liferay Developer Studio: These tools simplify theme development by providing built-in support for Liferay projects.
  • Node.js and npm: Liferay themes rely on npm for managing front-end dependencies.
  • Yeoman: This scaffolding tool helps generate Liferay theme projects.

Once these tools are in place, proceed to set up your Liferay 7 DXP instance to test your theme.

2. Install the Liferay Theme Generator

The Liferay Theme Generator is an npm package that automates much of the theme creation process. To install it globally, run the following command:

bash
npm install -g generator-liferay-theme

The generator scaffolds a new Liferay theme project by creating all the necessary folders and configuration files. After installation, confirm it’s working by running:

bash
yo liferay-theme

3. Create a New Theme

Run the following command in your terminal to create a new theme project:

bash
yo liferay-theme

You’ll be prompted to provide:

  • Theme Name: The name of your theme.
  • Liferay Version: Choose the version you’re working with, in this case, Liferay 7 DXP.
  • Theme ID: A unique identifier for your theme.
  • Base Theme: You can choose a blank theme or an existing one (e.g., _styled or _unstyled).

This step generates a project structure with folders, where you can start customizing the theme.

4. Modify Theme Files

Your primary customization work happens in the src folder. Here’s what each folder typically contains:

  • CSS: Define your theme’s styling in this directory. Use SCSS for advanced styling capabilities.
  • Images: Add any custom images for backgrounds, icons, or logos.
  • Templates: FreeMarker templates like portal_normal.ftl and init_custom.ftl control the layout and dynamic behavior of your theme.
  • JavaScript: Add or modify JavaScript files to enhance interactivity.
  • Other assets: Fonts, videos, or other custom assets go here.

5. Customize FreeMarker Templates

FreeMarker templates (.ftl files) are crucial for defining the structure and layout of your theme.
For instance:

  • portal_normal.ftl controls the overall layout of the page.
  • navigation.ftl defines the structure of the navigation menu.

Modify these files to align with your design requirements.

6. Build and Deploy the Theme

Once you’ve customized your theme, it’s time to build and deploy it to your Liferay 7 DXP instance.

Use the following command to build your theme:

bash
gulp build

This generates a .war file in the dist folder, ready for deployment. Deploy the theme using one of the following methods:

  • Deploy via the Deploy Folder: Copy the .war file to the deploy folder of your Liferay server.
  • Deploy via Control Panel: Upload the .war file through the Theme Management section in the Liferay Control Panel.

After deployment, activate your theme from the Control Panel to see the changes.

7. Test and Debug

Testing is a critical step to ensure your theme works as intended across various devices and browsers.

  • Use browser developer tools to inspect elements and troubleshoot layout or styling issues.
  • If your theme uses custom JavaScript, check the browser console for errors.

For advanced debugging, you can enable verbose logging in Liferay.

8. Iteratively Improve the Theme

Liferay themes often require iterative improvements based on user feedback or additional requirements. Common enhancements include:

  • Optimizing the theme for mobile responsiveness.
  • Adding accessibility features for a broader audience.
  • Fine-tuning the loading speed by minimizing CSS and JavaScript files.

9. Collaborate with Liferay Experts

While developing a Liferay theme can be a rewarding experience, it can also be complex and time-intensive. Collaborating with professionals from Liferay Development Services ensures that your theme meets high-quality standards and integrates seamlessly with your business needs.

If your team lacks the in-house expertise, hire Liferay developers to guide you through the process. Experienced developers bring deep knowledge of best practices, ensuring your theme is scalable and future-proof.

10. Publish Your Theme

If you’re building a theme for multiple stakeholders or clients, consider packaging and publishing it in the Liferay Marketplace. This opens up opportunities for broader adoption and recognition of your development efforts.

Best Practices for Liferay Theme Development

To create a successful and maintainable theme, follow these best practices:

  • Keep It Modular: Organize your assets (CSS, JS, images) logically to make updates easier.
  • Use Variables: Leverage SCSS variables to maintain consistency in colors, fonts, and other styling properties.
  • Optimize Performance: Minimize resource loading times by compressing files and optimizing images.
  • Follow Liferay Standards: Adhere to Liferay’s guidelines for FreeMarker and other components to ensure compatibility.
