Introducing LoginApp

Published: October 7, 2025

I wanted a project to practice building a full-stack application with modern web technologies, but also something more than just a functional app. LoginApp gives me a safe environment to experiment with security practices, helping me understand how vulnerabilities arise and how to address them effectively.

I built LoginApp with Next.js 15, which provides a full-stack framework for handling both frontend and backend in one place. Each page, like login, registration, and dashboard, automatically becomes a route, keeping the project structure simple and organized. I use React 19 for the interface, allowing me to create reusable components for input fields, buttons, and forms, and manage user input with real-time feedback, such as checking password strength or confirming that both passwords match. For styling, I use Tailwind CSS 4, which lets me apply styles directly in the components without switching between files.

Users can register a new account, log in, and access their dashboard. During registration, the app offers feedback to ensure passwords are strong and match the confirmation. Once logged in, the dashboard greets the user and includes a basic logout action.

Security is a central focus. Passwords must meet requirements for minimum length, uppercase letters, numbers, and special characters. Forms provide real-time guidance so users can fix issues before submitting. These features let me practice secure coding while creating a smoother experience. By building them myself, I can experiment with vulnerabilities and learn how to prevent them in real-world applications.

I plan to add more frontend features in the future, but for now, I want what I’ve built to feel complete for this stage. Once the frontend is ready, I’ll focus on the backend and security, using the OWASP Top 10 list to guide the identification and mitigation of common vulnerabilities.

Stay tuned to see how this app evolves into a secure, full-stack Next.js application!
