This project is a full-stack application designed to handle user registration, authentication, and protecting routes that return sensitive data. It utilizes a token-based authentication system on the backend and a React.js frontend with Redux state management. It was built using Node.js, Express, MongoDB on the backend, and React.js, Redux, React Router on the frontend. The full application is deployed on Google Cloud and Netlify.

The main challenge of this project was to develop a system that securely handles user registration, authentication, and provides access to protected data. The backend API provides several routes for these actions, all of which are secured using token-based authentication. The frontend part of the project provides a user-friendly interface for registration, login, and viewing protected data.

• Node.js
• Express
• CORS
• Mongoose
• MongoDB
• bcrypt
• crypto
• React.js
• Redux
• React Router
• MaterialUI

• User registration with password complexity requirements
• User sign-in with password matching
• Authenticated access to protected data
• Token-based user session management
• Redux state management for user and secret data
• Routing with React Router

A user in the database is defined with the following properties:

• username: A string that is required and unique.
• password: A string that is required.
• accessToken: A string that is unique for each user and generated when a new user is created.

• Startpage
• Register
• Login
• Secrets
• NotFound

Backend:

• / - GET route that returns the list of available endpoints
• /register - POST route to register a new user
• /login - POST route to authenticate a user and return a token
• /secrets - GET route that requires authentication and returns sensitive data

Frontend:

• / - Startpage
• /register - User registration page
• /login - User login page
• /secrets - Page that displays authenticated content from the API
• /* - 404 page
