This project is a simple web application built with Actix Web, a powerful, pragmatic, and extremely fast web framework for Rust.

• Hello World: A simple route that responds with "Hello world".
• User Management: Basic CRUD operations for user management.

• Rust 1.41 or higher
• Cargo
• MongoDB

To start the project run:

cargo run

This project uses MongoDB for persistent storage of user data, leveraging the MongoDB Rust driver for database operations within the Actix Web framework.

Before running the application, ensure you have MongoDB installed and running on your system. You can download MongoDB from the official site and find installation instructions for your operating system.

The application connects to MongoDB using the establish_connection function defined in the db module. This function initializes a MongoDB client and connects to a database named db. You can modify the database name and connection details (e.g., host, port) as needed in the src/db/connection.rs file.

The application's state (AppState) includes a MongoDB Database instance, which is passed to route handlers to perform CRUD operations on the users collection.

• Create User: To add a new user, send a POST request to /users with a JSON body containing the user's details. For example:

curl -X POST http://localhost:8080/users -H "Content-Type: application/json" -d '{"id": 1, "name": "John Doe", "email": "[email protected]"}'

• Get User: To retrieve a user by their ID, send a GET request to /users/{id}. Replace {id} with the actual user ID. For example:

curl -X GET http://localhost:8080/users/1

• Update User: To update a user's details, send a PUT request to /users/{id} with a JSON body containing the updated user details. For example:

curl -X PUT http://localhost:8080/users/1 -H "Content-Type: application/json" -d '{"name": "Jane Doe", "email": "[email protected]"}'

• Delete User: To delete a user by their ID, send a DELETE request to /users/{id}. Replace {id} with the actual user ID. For example:

curl -X DELETE http://localhost:8080/users/1
