Features

Powerful capabilities built into a clean, modular architecture

Modular Design

Domain-specific APIs cleanly separated into home, profile, and auth modules for improved maintainability.

/src/api/home
/src/api/profile
/src/auth

JWT Middleware

Secure authentication with JSON Web Tokens, easily integrated across all routes requiring protection.

/src/middleware/jwt.rs
/src/middleware/api_key.rs

Static Hosting

Serve HTML, CSS, and assets directly from your Rust backend with efficient resource handling.

/src/static/auth/login.html
/src/static/auth/signup.html
/src/static/auth/logo.png

Scalable Routing

Clean separation of routes and handlers for intuitive API endpoint management and expansion.

/src/routes.rs
/src/handlers.rs

Environment Support

Seamless configuration across development, testing, and production environments with .env integration.

/.env
/Cargo.toml

Rust Performance

Leverage Rust's speed and memory safety for highly efficient API endpoints with minimal overhead.

/src/main.rs
/src/api/**/*.rs

Ready for Production

A complete backend solution with the performance and safety guarantees of Rust.

About

Built for Maintainability

This architecture follows domain-driven design principles with clear separation of concerns. Each module is self-contained and focuses on a specific functionality domain.

Rust's Safety and Speed

Leveraging Rust's memory safety guarantees and zero-cost abstractions, this backend delivers exceptional performance without sacrificing security or reliability.

Clear API Layers

The project maintains a clean separation between routing, handlers, and business logic. This makes it easy to understand, extend, and test each component independently.

Architectural Overview

Routes Layer

# routes.rs
pub fn configure(cfg: &mut web::ServiceConfig) {
    cfg.service(
        web::scope("/api")
            .service(auth::endpoints())
            .service(profile::endpoints())
            .service(home::endpoints())
    );
}

Handlers Layer

# handlers.rs
pub async fn get_profile(
    req: HttpRequest,
    auth: AuthToken,
    path: web::Path<ProfileId>
) -> Result<HttpResponse, Error> {
    // Implementation
    Ok(HttpResponse::Ok().json(profile))
}

Core Logic Layer

# profile/mod.rs
pub struct Profile {
    id: ProfileId,
    username: String,
    email: Email,
    created_at: DateTime<Utc>
}
impl Profile {
    // Methods...
}
