Deploy React Website and Fix Contact Form

I have an AI-generated website built with React 19, Vite, Tailwind CSS V4, and TypeScript, created using Figma Make. I need help deploying it to my server and ensuring the contact form works correctly. The work includes setting up the site on the server, resolving any deployment issues, and making the contact form functional so messages are sent properly. Please share relevant experience with similar projects and your approach to troubleshooting deployment and form issues.
