## Project Structure



- **Backend**: Contains the Express.js server with RESTful endpoints for user registration, login, and data retrieval. It uses MongoDB for data storage and JWT for secure authentication.

- **Frontend**: Built with React and TypeScript using Vite as the build tool. It provides a user interface for registration, login, and viewing user data, with JWT tokens stored in cookies for session management.



## Backend



### Features



- **User Registration** (`POST /registration`): Allows new users to register with a username, password, full name, and email.

- **User Login** (`POST /login`): Authenticates users and returns a JWT token upon successful login.

- **Protected Route** (`GET /user`): Retrieves user-specific data, accessible only with a valid JWT token.



### Dependencies



- `express`: Web framework for Node.js

- `mongoose`: MongoDB object modeling tool

- `jsonwebtoken`: Library for JWT creation and verification

- `cors`: Middleware to enable Cross-Origin Resource Sharing

- `dotenv`: Loads environment variables from a `.env` file

- `nodemon`: Development utility for auto-reloading server code



### Scripts



- `start`: Runs the server with nodemon for development



### Running the Backend



1. Install dependencies: `npm install`

2. Start the server: `npm start`



## Frontend



### Features



- **Registration View**: Form for user registration.

- **Login View**: Form for user login, storing JWT tokens in cookies.

- **Users View**: Displays user data fetched from the backend.



### Dependencies



- `react`: JavaScript library for building user interfaces

- `react-dom`: DOM rendering for React

- `react-router-dom`: Routing library for React

- `styled-components`: Library for styling React components

- `js-cookie`: Utility for handling cookies



### Dev Dependencies



- `vite`: Build tool for modern web projects

- `typescript`: Superset of JavaScript with static typing

- `eslint`: Linter for identifying and fixing problems in code



### Scripts



- `dev`: Starts the development server with Vite

- `build`: Builds the project for production

- `lint`: Runs ESLint to check for code quality issues

- `preview`: Previews the built project locally



### Running the Frontend



1. Install dependencies: `npm install`

2. Start the development server: `npm run dev`



## MongoDB Setup



For local development, you can install and set up MongoDB on your machine by following the [official MongoDB installation guide](https://www.mongodb.com/docs/manual/installation/).



For production, consider using [MongoDB Atlas](https://www.mongodb.com/cloud/atlas) or another cloud-based MongoDB service.



## Environment Variables



Make sure to create a `.env` file in the backend directory with the following environment variable:



- `SECRETE_ACCESS_TOKEN`: Secret key used for signing JWT tokens
