JaivishChauhan Contact Form Implementation
Overview
A production contact form requires:
- Type-safe validation (Zod)
- Efficient form state (React Hook Form)
- Server-side processing (Server Actions)
- Email delivery (Resend/SendGrid)
- Rate limiting (Upstash Redis)
- User feedback (Toast notifications)
Dependencies
npm install react-hook-form @hookform/resolvers zod resend
npm install sonner # Toast notifications
npm install @upstash/ratelimit @upstash/redis # Rate limiting (optional)
Form Schema
// lib/schemas/contact.ts

* Contact form validation schema.
* @security Validates all input server-side.

email: z
.string()
.email("Please enter a valid email")
.max(255, "Email is too long")
.toLowerCase(),
subject: z

.min(5, "Subject must be at least 5 characters")
.max(200, "Subject is too long"),
message: z
.string()

Testing Checklist
- Form validates on blur
- Server validation catches bypassed client validation
- Honeypot rejects bots silently
- Rate limiting works (test with multiple submissions)
- Email sends correctly
- Auto-reply sends (if implemented)
- Success state displays properly
- Error messages are clear and actionable
- Form is accessible (labels, ARIA, keyboard nav)
- Loading state prevents double submission
