Next.js 15 and React 19 full-stack course

Our analysis

Next.js 15 y React 19 | Clon de Linktree Fullstack completo is a single-project course: you build a Linktree-style application from start to finish with a modern JavaScript stack. We would recommend it to people who already know the basics of React and want to see how authentication, a database, file uploads and the interface connect in practice, in an app you can show in a portfolio.

Who it is for

• Developers with basic JavaScript and React knowledge who want to build their first full-stack project.
• People who learn better by following a complete project than through isolated exercises.
• Anyone who wants to get to know current ecosystem tools such as shadcn, Clerk, Prisma or Uploadthing.

What it covers

• Dynamic, responsive interfaces with Next.js 15 and React 19.
• Styling with Tailwind CSS and reusable shadcn components.
• Sign-up, login and user profiles with Clerk.
• Modeling a relational database on Neon and using Prisma for models, migrations and queries.
• Image uploads with Uploadthing and HTTP requests with Axios, including data validation and error handling.
• Interactivity and animations in the interface.

What to keep in mind

• The course is taught in Spanish.
• It relies on several external services (Clerk, Neon, Uploadthing) whose free tiers and dashboards change over time; some screens may not match what you see today.
• It is tied to Next.js 15 and React 19; if you use a newer version, expect minor adjustments.
• As a single project, it does not replace a React fundamentals course, and the description does not mention automated testing or deployment.

Where it fits in a path

Come in with modern JavaScript and React basics (components, props and state); that foundation is covered in the "Web developer roadmap". This course works as a capstone project after a fundamentals course. Since it uses a relational database through Prisma, it is worth reviewing queries and relationships with "How to learn SQL from scratch" so you understand what happens behind the ORM. If you later want to deploy to the cloud on your own, the "AWS Cloud Practitioner certification" guide gives you the basic vocabulary.
