How to Create Custom Components in Pega?

Pega comes with many ready-to-use UI components. But sometimes, business requirements cannot be achieved using the standard components. In such situations, developers can create Custom Components to add extra functionality or build a unique user experience.

Custom components can be reused in different parts of an application, which helps save development time and keeps the user interface consistent.

When Do We Use Custom Components?

You can use custom components when:

1. Standard Pega components do not meet your requirement.
2. You need a special UI feature or behavior.
3. You want to integrate an external library or API.
4. The same UI element is needed in multiple places.
5. You want a consistent look and feel across the application.

Steps to Create a Custom Component in Pega

1. First, identify what functionality or UI feature you need and why the standard components are not enough.
2. Plan how the component should look and work. Decide what inputs and outputs it will have.
3. Develop the custom component and add it to your Pega application.
4. Define the properties or parameters that the component will use to display and process data.
5. Implement the required functionality, validations, and styling.
6. Test the component in different scenarios to make sure it works as expected.
7. Once testing is complete, the component can be used in multiple views and applications whenever needed.

Benefits of Custom Components

1. The same component can be used in different screens and applications.
2. Helps maintain a uniform user experience throughout the application.
3. Develop once and reuse multiple times.
4. Changes made to the component are automatically reflected wherever it is used.
5. Makes it easier to add new features in the future.

Conclusion

Custom Components help developers extend Pega applications when standard components are not enough. They improve reusability, maintain consistency, reduce development effort, and make applications easier to maintain and enhance over time.
