Client-side validation is validation of submitted data performed in the user's browser before a request is processed by a server.
Client-side validation checks submitted form data in the browser before the registration request reaches the server, giving immediate feedback for basic errors. section 8.2
Apply HTML constraints directly to registration fields:
Reserve cross-field checks, such as matching password and confirmation values, for the server handler. section 8.2
Tutor registration
A registration form posts to /register only after the browser checks required fields and username length; handle_register() then validates password confirmation. section 8.2
How Rust Servers, Services, and Apps covers it
How deep it goes
Demonstrates required fields and length limits, while deferring password confirmation to server-side validation.
Examples
Uses tutor registration fields with required, minlength, and maxlength attributes as concrete validation examples.
What you can do after
Apply it via HTML form attributes to enforce mandatory fields and basic field lengths in a browser.
How it connects
Connects HTML forms with HTTP POST requests, server-side validation, and Actix Web request handlers.
