Next.js 13 + App Router + MongoDB - User Rego and Login Tutorial with Example

FastAPI Backend

This is a FastAPI backend application for handling user authentication and database interactions. It uses MongoDB as the database and JWT for authentication.

Installation

1. Clone the repository: git clone https://github.com/your-username/your-repo-name.git
2. Navigate to the project directory: cd your-repo-name
3. Create a virtual environment: python -m venv venv
4. Activate the virtual environment: source venv/bin/activate (on Linux/Mac) or venv\Scripts\activate (on Windows)
5. Install the required packages: pip install -r requirements.txt
6. Start the MongoDB server: mongod (on Linux/Mac) or mongod.exe (on Windows)
7. Start the FastAPI server: uvicorn main:app --reload

Configuration

The application uses environment variables for configuration. The following variables are required:

• MONGODB_URI: The URI of the MongoDB instance.
• JWT_SECRET: The secret key for generating JWT tokens.

You can set these variables in your environment or in a .env file.

API Endpoints

The application has the following API endpoints:

• POST /register: Registers a new user.
• POST /login: Logs in an existing user and returns a JWT token.
• GET /users: Returns a list of all users.

Best Practices

Security

• Use secure passwords and keep them confidential.
• Use HTTPS for secure communication between the client and server.
• Validate user input to prevent SQL injection and other attacks.
• Use secure protocols for authentication and authorization.

Code Quality

• Follow the PEP 8 style guide for Python code.
• Use meaningful variable names and comments to make the code readable.
• Keep functions short and focused on a single task.
• Use type hints and docstrings to document the code.

Testing

• Write unit tests for individual functions and modules.
• Write integration tests for API endpoints and workflows.
• Use a testing framework such as Pytest or Unittest.
• Test for both happy paths and error scenarios.

Deployment

• Use a containerization tool such as Docker for deployment.
• Use a cloud platform such as AWS or GCP for hosting.
• Use a CI/CD pipeline for automated testing and deployment.
• Monitor the application for performance and security issues.

Documentation

• Write clear and concise documentation for the API endpoints.
• Use tools such as Swagger or OpenAPI for generating documentation.
• Document the installation, configuration, and deployment process.
• Keep the documentation up-to-date with changes to the code.

Collaboration

• Use version control systems such as Git for collaboration.
• Use branching and merging for managing changes.
• Use pull requests for code reviews.
• Use issues and project management tools for tracking tasks and bugs.
