Does a Reactive Web App request data synchronously or asynchronously?

In a Reactive Web App, data is requested asynchronously. This means that when a request for data is made, the application can continue executing other tasks without waiting for the response. This non-blocking nature enhances the user experience by allowing the interface to remain responsive while awaiting data from the server.

When using asynchronous requests, the application can show loading indicators, handle user interactions, or perform other operations while the data is being fetched in the background. This approach is particularly beneficial in web applications, where delays in data retrieval could lead to a poor user experience.

The asynchronous model is a standard approach in modern web application development, aimed at optimizing performance and enhancing user interactivity. By leveraging this method, OutSystems allows developers to create more dynamic and fluid applications that can effectively handle operations without freezing or becoming unresponsive during data retrieval processes.
