This project is features an HTTP server written in Rust using the Actix-Web framework. It provides a booking management system for dog walkers, with endpoints for managing owners, dogs, and bookings.

For a detailed tutorial on how to build this project, check out my Rust Web Server Tutorial on Medium.

Ensure you have Rust and Cargo installed on your system. You can check by running:

rustc --version
cargo --version

If Rust is not installed, follow the instructions on the official Rust website.

Clone the repository to your local machine:

git clone https://github.com/BretCameron/rust-web-server-tutorial

Navigate into the project directory. For project development, you can use the following command:

cargo watch -c -w src -x run

The server will start running on http://127.0.0.1:5001.

The application is configured to connect to a MongoDB database. It attempts to read the MONGO_URI environment variable to establish a connection. If MONGO_URI is not set, it defaults to connecting to a local MongoDB instance.

For local development, you can change the default connection string in the src/db.rs file. Just make sure not to commit any sensitive information!

Otherwise, to set an environment variable for the MongoDB URI, follow the instructions below.

To connect to your MongoDB instance, you need to set the MONGO_URI environment variable to your database’s URI string. Here's how you can do it:

On UNIX/Linux/MacOS: Open your terminal and enter the following command (replacing <your_mongo_uri> with your actual MongoDB URI):

export MONGO_URI=<your_mongo_uri>

On Windows:

Open Command Prompt and execute the following command (again, replace <your_mongo_uri> with your MongoDB URI):

set MONGO_URI=<your_mongo_uri>

The application exposes several HTTP endpoints:

• GET /: Returns a simple greeting. Used to check if the server is running.
• POST /owner: Creates a new owner.
• POST /dog: Adds a new dog, associating it with an owner.
• POST /booking: Creates a new booking.
• GET /bookings: Retrieves all bookings.
• PUT /booking/{id}/cancel: Cancels a specific booking.

You can use tools like Postman or cURL to interact with the API.
