How to Boost App Performance by Updating UI Before Database Uploads

Developing your first app can be both exciting and challenging. One common issue developers face is ensuring that their app runs smoothly while providing a seamless user experience. If you've been dealing with long loading times when users upload items, you're not alone! Many developers struggle with how to balance safety with performance. In this guide, we will explore how to improve your app's performance by rethinking the order of operations in your item upload workflow.

The Problem: Slow User Experience

In your current app workflow, when a user presses the add button, the following steps occur:

User presses the add-Button.

The app uploads the item to Cloud-Firestore.

The app waits for the upload to finish.

The UI is updated, and UserDefaults is set.

This approach runs into performance issues, particularly when the items being uploaded are large. Users are left staring at a loading indicator, which can lead to frustration and a diminished experience. But the good news is, there’s a way to enhance performance while still keeping your app safe and functional!

The Solution: Reverse the Workflow

Instead of waiting for the item upload to complete before updating the UI, you can switch the order of operations. Here’s how to do it effectively:

1. Update UI Immediately

As soon as the user taps the add-Button, update the UI. This gives immediate feedback, making the user feel like the action has been registered, which is crucial for a positive experience.

2. Upload in the Background

Upload the item to the cloud in a background thread. This means the upload process won’t freeze the app's UI or block user interaction.

3. Listen for Completion

Listen for the completion of the upload. Once the upload is finished, you can check the result (success or failure) and respond accordingly.

4. Handle Upload Results

If the upload is successful, then update the UserDefaults.

If the upload fails, it is essential to provide feedback to the user. This can be done through notifications, alerts, or banners to inform them about the failure and possibly allow them to retry.

5. Consider a Retry Mechanism

To further enhance user experience, consider implementing a retry mechanism for failed uploads due to network errors. This allows users to attempt to resend their data instead of being left with an uncertain or confusing situation.

Conclusion: Enhanced User Experience

By updating the UI before waiting for a database operation to complete, you're not just improving app performance; you're also enhancing user satisfaction. Users appreciate responsiveness, and a more dynamic interface can make all the difference.

This approach is used by many successful apps in the market, such as Todoist and Wunderlist, which prioritize user experience while ensuring backend processes function efficiently.

Final Thoughts

In mobile app development, user experience and performance are paramount. By implementing the strategies discussed above, you can vastly improve the interaction your users have with your app while maintaining data integrity and safety. Happy coding!
