# When do client activities execute in Nanoflows?

Client activities in Nanoflows are a core feature that enhances the performance and user experience of your Mendix applications by executing directly in the end-user’s browser, rather than going through the server. Let’s dive deeper into when and how these client activities execute to understand their full potential.

## The Execution Process of Client Activities

Client activities in Nanoflows operate at **each step where they are placed** within a Nanoflow. This occurs as soon as the preceding operation has been completed, ensuring immediate execution directly on the client side. This immediate execution is a key factor in achieving a smoother user interface and faster feedback times.

## Benefits of Client Activities

Executing client activities on the client side offers several significant advantages, making it an valuable addition to your application:

1. **Offline Functionality:** Since client activities run in the browser, they can operate even when the device is not connected to the internet. This capability is particularly useful in scenarios where connectivity can be unpredictable or inconsistent.

2. **Enhanced Responsiveness:** By eliminating the need to wait for server processing, the application can provide instant feedback to user inputs, making interactions more intuitive and fluid.

## Concrete Example

Consider a form where users enter data. Traditionally, each change might trigger a server call to validate the input. With client activities, however, you can validate the input directly on the client side. As a result, users receive immediate feedback without any delay, improving the overall user experience and satisfaction significantly.

## Conclusion

Client activities in Nanoflows are a powerful tool for enhancing the interactivity and responsiveness of your applications. Understanding when these activities execute is crucial for designing more efficient applications that can provide an excellent user experience both online and offline. By leveraging these capabilities, you can significantly improve the speed and quality of user interactions, making your applications more engaging and user-friendly.
