Form Validation

This covers client-side form validation across React Hook Form, Formik, and Vue's Vee-Validate, plus custom validator patterns. You get TypeScript-safe implementations for common scenarios like login and registration forms, real-time error feedback, and multi-step flows. The reference guides walk through each library's approach, which is helpful if you're jumping between frameworks or haven't settled on a validation strategy yet. The server-side validation integration guide is the most useful part since that's where most forms get messy. Solid for teams that need consistent validation patterns across different projects, though you'll still need to adapt the examples to your specific backend and error handling setup.
