🚀 RabbitMesh - Message-Driven Microservices Framework

Zero-port microservices with auto-generated APIs

RabbitMesh eliminates traditional microservice complexity by using RabbitMQ for all inter-service communication. Write business logic, get REST + GraphQL APIs automatically.

✨ Key Features

• 🔥 Zero Port Management - Services only connect to RabbitMQ
• ⚡ Never Blocks - Every request spawns async task
• 🎯 Auto-Generated APIs - Write service methods, get REST + GraphQL
• 🛡️ Production Ready - Built-in retries, timeouts, load balancing
• 🌍 Deploy Anywhere - Docker, Kubernetes, bare metal

🚀 Quick Start

1. Define Your Service

use rabbitmesh_macros::{service_definition, service_method};

#[service_definition]
pub struct UserService;

impl UserService {
    #[service_method("GET /users/:id")]
    pub async fn get_user(user_id: u32) -> Result<User, String> {
        // Your business logic only
        Ok(User { id: user_id, name: "John".to_string() })
    }
    
    #[service_method("POST /users")]  
    pub async fn create_user(data: CreateUserRequest) -> Result<User, String> {
        // Handle user creation
        Ok(User { id: 1, name: data.name })
    }
}

2. Start Your Service

use rabbitmesh::MicroService;

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let service = MicroService::new("amqp://localhost:5672").await?;
    service.start().await?;  // Never blocks, handles requests concurrently
    Ok(())
}

3. Auto-Generated API Gateway

use rabbitmesh_gateway::create_auto_router;

#[tokio::main] 
async fn main() {
    let app = create_auto_router().await;
    
    // Automatically provides:
    // GET  /api/v1/user-service/users/123
    // POST /api/v1/user-service/users
    // GraphQL endpoint at /graphql
    
    axum::Server::bind(&"0.0.0.0:3000".parse().unwrap())
        .serve(app.into_make_service())
        .await
        .unwrap();
}

🎯 Why RabbitMesh?

🚀 Performance

• Latency: 3-10ms (vs 1-5ms HTTP direct)
• Throughput: Higher than HTTP (persistent connections)
• Concurrency: Unlimited (every request = async task)
• Scalability: Linear (add instances = proportional capacity)
