Next.js for Builders
Next.js is the framework behind RadarTrek, most modern SaaS products, and hundreds of thousands of production sites. It adds file-based routing, server-side rendering, API routes, and one-click Vercel deployment on top of React. This course teaches Next.js through building a real product — you leave with a deployed, full-stack web app.
