Crate ferreiro 

Ferreiro

A Django-inspired web framework for Rust, built on hexagonal architecture. For developers who want to build, not configure.

⚠️ Alpha Release: Ferreiro is in early development (v0.0.x). The core architecture is solid, but many features are still being implemented.

What Works Now

• ✅ Domain modeling with value objects and events
• ✅ In-memory repositories for testing
• ✅ HTTP server (Axum-based)
• ✅ Template engines (Tera, MiniJinja)
• ✅ Session management

Quick Start

use ferreiro::prelude::*;
use std::sync::Arc;

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    // Setup repositories
    let repo = Arc::new(InMemoryPostRepository::new());
    let events = Arc::new(InMemoryEventPublisher::new());

    // Create service
    let service = Arc::new(PostServiceImpl::new(repo, events));

    // Create a post
    let post = service.create(CreatePostCommand {
        title: "Hello World".to_string(),
        slug: "hello-world".to_string(),
        body: "My first post".to_string(),
        author_id: UserId::generate(),
    }).await?;

    // Build HTTP API
    let app = Router::new()
        .route("/", get(|| async { "Welcome to Ferreiro!" }));

    // Start server
    serve(app, "127.0.0.1", 8000).await?;
    Ok(())
}

Architecture

Ferreiro follows hexagonal (ports and adapters) architecture:

• Domain: Pure business logic with zero framework dependencies
• Ports: Trait interfaces for repositories and services
• Adapters: Implementations for HTTP, databases, templates, etc.

This keeps your domain clean and makes everything swappable and testable.

Modules

• domain: Domain models, value objects, and ports
• application: Service implementations and use cases
• db: Database adapters (currently in-memory, PostgreSQL/SQLite coming)
• http: HTTP server and routing
• templates: Template engines (Tera, MiniJinja)
• session: Session management
• admin: Admin interface (coming soon)
• prelude: Convenient imports for common use cases
