Many frameworks such as Laravel do not offer any suggestions on how to do validation. This is clear from the backend framework.
But it would be nice to provide a preliminary javascript check in advance so that users can immediately see if something is wrong when they fill out the form.
I know how to do validation on a server with something like Laravel, and I know how to do it on an interface with javascript. The problem that arises is that many frameworks do not cross this interface / backend border, but I need to keep them validated in synchronization with eachother.
I can’t have validation errors on the interface that no longer apply to backend validation. How do people deal with this?
As a rule, people just do authentication and transfer flash memory or errors to the user and just skip the compliance check? I feel that trying to keep the validation for the interface and backend the same can be error prone and work quite a bit.
Edit
Although this question already has an answer, I would like more information about it. What people use, custom solutions or thoughts on how to effectively solve this problem are welcome.
