Ironic

A batteries-included, type-safe application framework for building structured Rust APIs on top of Axum. Inspired by NestJS's modular architecture, grounded in Rust's type system.

Quick Start

cargo install ironic
ironic new my-api
cd my-api
ironic start

Features

Modular architecture — modules, imports, exports, provider visibility
Dependency injection — singletons, transients, factories, cycle detection
HTTP routing — Axum adapter, controllers, parameter extraction, validation
Request pipeline — middleware, guards, interceptors, error handling
Procedural macros — #[derive(Injectable)], #[Module], #[controller], #[get], #[post]
Testing utilities — in-process test app, provider overrides, fluent assertions
CLI — project scaffolding, code generators, doctor command
OpenAPI — automatic schema generation, Swagger UI
Integrations — SQLx, SeaORM, Diesel, MongoDB, Redis, JWT, OAuth, gRPC, GraphQL

Example

use ironic::prelude::*;

#[derive(Injectable)]
#[controller("/users")]
struct UsersController {
    service: Arc<UsersService>,
}

#[routes]
impl UsersController {
    #[get("/:id")]
    async fn find_one(&self, #[param] id: Uuid) -> Json<UserResponse> {
        Json(self.service.find_one(id).await)
    }
}

#[derive(Module)]
#[module(controllers = [UsersController], providers = [UsersService])]
struct UsersModule;

#[ironic::main]
async fn main() {
    FrameworkApplication::builder()
        .module(AppModule::definition())
        .platform(AxumAdapter::new())
        .build()
        .await
        .unwrap()
        .listen("127.0.0.1:3000")
        .await
        .unwrap();
}
