When it comes to traditional web frameworks, the most important part is handling regular HTML forms. Reason being, a form is the only native mechanism your customers have to use to interact with your service. Forms are important. Specifically, validation and error handling. I think Laravel does it really well. It's been a while, but Laravel has a wrapper around HTML forms. This wrapper does everything you need: server-side form validation, form generation, flexible error handling that takes care of client error messages, placeholders, input values, css classes for invalid states, you name it.
