SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This skill consolidates patterns and examples to implement reliable client-side and server-synchronized form validation across React, Vue, and TypeScript projects, reducing user-facing errors and failed submissions.

Core Features & Use Cases

  • Real-time field validation: React Hook Form examples and a custom validator hook for immediate feedback and error state management.
  • Schema-based validation: Formik with Yup and Vee-Validate examples for declarative, reusable validation rules.
  • Async server validation & integration: Patterns for checking email/username availability and reconciling server-side errors with client forms.
  • Use Case: Build login and registration flows, multi-step signups, or complex forms that require both synchronous rules and async uniqueness checks while preserving TypeScript typings.

Quick Start

Create a TypeScript React Hook Form login and registration flow with real-time validation, Yup/Formik and Vee-Validate examples, and an async email availability check integrated with the server.

Frequently Asked Questions about form-validation

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I implement type-safe form validation in a React and TypeScript project?

Schema-based validation with Formik and Yup is implemented by defining declarative, reusable validation rules. This approach allows you to specify validation schemas separately from your UI components, making rules easier to maintain and test.

How do I check email or username availability with async server validation?

Async server validation for checking email or username availability is implemented using patterns that query the server and reconcile server-side errors with client forms. This skill covers integrating async availability checks directly into your validation flow.

Can I use Vee-Validate for schema-based validation in Vue applications?

Real-time field validation in multi-step signups is handled through React Hook Form examples and custom validator hooks that manage immediate feedback and error states across steps. This skill provides patterns for complex forms requiring both synchronous rules and async checks.

What is the best way to reconcile server-side errors with client form validation?

The best way to reconcile server-side errors with client form validation is using patterns that map server responses back to specific form fields. This skill demonstrates how to integrate async server validation and display errors within your existing client-side validation logic.
