MongoDB Restaurants CRUD with Multiple Web Frameworks

This project demonstrates how to implement a CRUD application for a restaurant database using MongoDB and various Rust web frameworks.

Prerequisites

• Rust (latest stable version)
• MongoDB running locally or accessible via network
• MongoDB Atlas (sample dataset)[https://www.mongodb.com/docs/atlas/sample-data/] loaded in

Setup

1. Clone the repository
2. Copy .env.example to .env and configure your MongoDB connection string
3. Load the sample restaurants database if not already loaded:

mongosh
use sample_restaurants

Running the Application

cargo run

The application will prompt you to choose a web framework implementation:

1. None (MongoDB driver only) - Interactive CLI
2. Actix Web (http://localhost:8080)
3. Axum (http://localhost:8081)
4. Rocket (http://localhost:8082)
5. Warp (http://localhost:8083)
6. Tide (http://localhost:8084)

API Endpoints (for Web Framework Implementations)

All web framework implementations expose the same REST API endpoints:

Create Restaurant

• POST /api/restaurants
• Body: Restaurant JSON

List Restaurants

• GET /api/restaurants
• Returns first 10 restaurants

Get Restaurant

• GET /api/restaurants/{id}
• Returns restaurant by ObjectId

Update Restaurant

• PUT /api/restaurants/{id}
• Body: Update JSON document

Delete Restaurant

• DELETE /api/restaurants/{id}
• Deletes restaurant by ObjectId

Sample Restaurant Document

{
  "address": {
    "building": "8825",
    "coord": [-73.8803827, 40.7643124],
    "street": "Astoria Boulevard",
    "zipcode": "11369"
  },
  "borough": "Queens",
  "cuisine": "American",
  "grades": [
    {
      "date": "2014-11-15T00:00:00.000Z",
      "grade": "Z",
      "score": 38
    }
  ],
  "name": "Brunos On The Boulevard",
  "restaurant_id": "40356151"
}

Implementation Details

• src/models/restaurant.rs - Restaurant data model
• src/db/mongodb.rs - MongoDB repository implementation
• src/frameworks/ - Web framework implementations
• src/error.rs - Error handling
• src/main.rs - Framework selection and startup

Testing the API

You can test the API endpoints using curl, Postman, or any HTTP client. Example curl commands:

# List restaurants
curl http://localhost:8080/api/restaurants

# Get restaurant by ID
curl http://localhost:8080/api/restaurants/5eb3d668b31de5d588f42930

# Create restaurant
curl -X POST http://localhost:8080/api/restaurants \
  -H "Content-Type: application/json" \
  -d '{"name":"New Restaurant","borough":"Manhattan",...}'

# Update restaurant
curl -X PUT http://localhost:8080/api/restaurants/5eb3d668b31de5d588f42930 \
  -H "Content-Type: application/json" \
  -d '{"name":"Updated Name"}'

# Delete restaurant
curl -X DELETE http://localhost:8080/api/restaurants/5eb3d668b31de5d588f42930

Replace the port number (8080) with the appropriate port for your chosen framework:

• Actix Web: 8080
• Axum: 8081
• Rocket: 8082
• Warp: 8083
• Tide: 8084
