Building a RESTful Todo API with Rust, Axum, and Diesel

Hey fellow developers! 👋 Today, I'm excited to share my journey building a robust Todo API using Rust's powerful ecosystem. This project showcases how to create a production-ready REST API with modern tools and best practices.

🦀 Why Rust?

Rust's safety guarantees, performance, and growing ecosystem make it an excellent choice for building reliable web services. Combined with Axum for routing and Diesel for ORM, we get a powerful foundation for our API.

🛠️ Tech Stack

  • Rust
  • Axum (Web framework)
  • Diesel (ORM)
  • PostgreSQL
  • Docker

✨ Key Features

  • Complete CRUD operations
  • RESTful endpoints
  • Database integration
  • Docker support
  • Scalable architecture

🚀 Getting Started

Setting up the project is straightforward:

# Clone and setup
git clone <your-repo>
cd todo

# Setup environment
cp .env.example .env

# Run migrations
diesel migration run

# Start the server
cargo run
Enter fullscreen mode Exit fullscreen mode

📡 API Endpoints 

POST /tasks   - Create a new task
GET /tasks    - List all tasks
GET /tasks/1  - Get a specific task
POST /tasks/1 - Update a task
DELETE /tasks/1 - Delete a task
Enter fullscreen mode Exit fullscreen mode

🏗️ Project Architecture

The project follows a clean architecture pattern:

  • Routes layer (API endpoints)
  • Service layer (Business logic)
  • Repository layer (Database operations)
  • Models (Data structures)

💡 Implementation Highlights

Here's a glimpse of how we handle task creation:

#[derive(Deserialize)]
struct CreateTask {
    title: String,
    description: Option<String>,
}

async fn create_task(
    Json(payload): Json<CreateTask>,
    State(db): State<Pool<Postgres>>,
) -> Result<Json<Task>, StatusCode> {
    // Implementation details
}
Enter fullscreen mode Exit fullscreen mode

🔄 Future Roadmap

We have exciting plans for the future:

  1. Authentication & Authorization
  • JWT implementation
  • Role-based access

  • OAuth2 support

    1. Enhanced Task Management

  • Categories/Tags

  • Priority levels

  • Due dates

  • Attachments

    1. Infrastructure

  • Docker containerization

  • Kubernetes deployment

  • Monitoring with Prometheus

  • Grafana dashboards

    1. Security

  • Input validation

  • SQL injection prevention

  • HTTPS enforcement

  • Rate limiting

    1. Frontend Development

  • React.js client

  • Mobile app with React Native

🔍 Learning Outcomes

Building this API taught me several valuable lessons:

  1. Rust's powerful type system for API design
  2. Structured error handling
  3. Database integration patterns
  4. API security best practices
