Debug authentication in a Next.js and NestJS todo app by validating registration and login, enabling cors, configuring backend urls via env, and handling jwt tokens in local storage or cookies.
Walk through finalizing a Next.js and NestJS todo app, debugging logout and authentication flows, testing multi-user isolation, and outlining fixes like dto validation and controller issues.
Conclude by acknowledging a login mishap that led to issues. Point learners to the GitHub code link and invite them to build on the todo app in future courses.
In this hands-on course, we will build a todo list application using Next.js, NestJS, MongoDB Atlas, Prisma, and Material UI – with user registration, authentication, and session handling.
I’m Lucas, a tech lead working in an international team. I’ve created this course to blend real developer experience with the power of modern AI-assisted tools like Cursor and ChatGPT.
Instead of learning a single technology in isolation — which we do in many of my courses — we’ll build a complete app step-by-step:
Next.js frontend using the App Router
NestJS backend with RESTful API
MongoDB Atlas with Prisma ORM
JWT-based session authentication
Material UI for forms and layout
Full CRUD operations for todos
GitHub commits after each major step
Everything is built live, from scratch — without any slides or boring theory. Just we, the code, and a fast workflow supported by modern dev tools.
No advanced knowledge is required. If you’ve used JavaScript before and want to build something real, this course will walk you through the process clearly and efficiently. We'll move fast but explain as we go — striking the right balance between learning and doing.
So no matter if you're just starting out or want to practice real full-stack building, this course is a great way to get a working project into your portfolio — and learn how modern tools can make you faster and better.
