🚀 go-aether

Lightning-fast, Zero-Runtime Dependency, Opinionated Enterprise Architecture CLI Engine for Go.

---

go-aether is a high-performance, developer-first CLI engine designed for modern Go Backend Engineers and Enterprise Architects. It eliminates the friction of boilerplate construction by scaffolding production-grade, strictly typed Hexagonal (Ports & Adapters) and Domain-Driven Design (DDD) architectures in milliseconds.

Unlike heavy opinionated frameworks, go-aether is strictly a Dev-Time Scaffolding Tool. It embeds clean standard text/template files into a single binary, generating pure, unencumbered Go code with zero runtime lock-in.

---

✨ Core Highlights & Capabilities

• 🏗️ Hexagonal Architecture (Ports & Adapters): Automatic separation of concerns across Domain, Port, Service, and Adapter layers.
• ⚡ Zero-Runtime Overhead: The generated code is 100% native Go. No external runtime frameworks required.
• 🛡️ Transactional Disk Buffer: Atomic multi-file writes with automatic rollback on generation error.
• 🩺 Aether Doctor: Built-in AST structural diagnostics against the Single Source of Truth (aether.yaml).
• 🔄 Distributed Systems Ready: Out-of-the-box CQRS, Transactional Outbox, Distributed Saga Orchestrator, and HMAC Signed Webhooks.
• ☁️ Cloud Native & Plugins: Native AWS S3, OAuth2 / API Key, In-Process Cron Scheduler, Mailer, Firebase Auth/FCM, and OpenTelemetry Tracing.
• 🔍 Brownfield AST Adoption: Scan legacy Go codebases and seamlessly adopt them into the Aether manifest.

🚀 Installation

Install the latest stable release via the standard Go toolchain:

go install github.com/muhananaufal/go-aether@latest

(Ensure $(go env GOPATH)/bin is in your system $PATH)

---

📖 Quick Start

1. Initialize a New Project

Bootstrap a clean architecture workspace and generate the master aether.yaml manifest:

mkdir my-service && cd my-service
go-aether init my-service --arch hexagonal --router chi --db postgres

2. Scaffold Vertical Domain Modules

Generate a complete vertical slice (order) including Domain Entities, Ports, Service Orchestrator, HTTP Handler, and Postgres Repository:

go-aether make:module order --transports http

3. Inject Distributed Patterns & Middlewares

Effortlessly add production-grade patterns into your codebase:

# Add CQRS Handlers & Command Bus for the Order domain
go-aether add:cqrs order

# Add Transactional Outbox pattern & SQL migrations
go-aether add:outbox

# Add Distributed Saga Workflow with compensation
go-aether add:saga checkout

# Add HMAC-SHA256 Signed Webhook Dispatcher & Receiver
go-aether add:webhook

# Add Cloud Storage (AWS S3 / MinIO) and In-process Cron Scheduler
go-aether add:storage s3
go-aether add:cron cleanup_orders

4. Run Structural Diagnostics

Verify your project's architectural compliance and detect drift:

go-aether doctor
