Is everything submitted to the server in OutSystems?

In OutSystems, the statement that not everything is submitted to the server is accurate because built-in validations are indeed performed on the client-side. When a user interacts with a web application, various inputs are subject to initial validations before any data is sent to the server. This is done to enhance user experience by providing immediate feedback on input errors, such as format issues or missing fields, without the need for a round-trip to the server.

Client-side validations help reduce unnecessary server processing by ensuring that only valid data is submitted. This is particularly useful in preventing common user errors, thus making applications more responsive and efficient. If the client-side validation fails, the submission process is halted, and the user is prompted to correct the errors right away.

Although there are validations that occur on the server-side to ensure data integrity and security, the primary point here is that initial validations are meant to be quick and efficient by being handled on the client. So, recognizing the role of client-side validations helps clarify why not everything is sent to the server in the OutSystems framework.
