gofiber-generator 0.1.0

A complete configuration-driven generator for Go Fiber applications

Go Fiber Generator

A comprehensive, configuration-driven code generator for Go Fiber backends. This toolset leverages Python and Jinja2 templates to produce a fully-featured, production-ready Go backend scaffold based on a declarative YAML configuration.

It handles everything from routing, controllers, and database models to authentication, RBAC, WebSockets, and Flutter client APIs.

🚀 Key Features

• App Scaffolding: Generates the core foundation (config, database connectivity, main application entry point, routing skeleton, and infrastructure files like Dockerfile and Makefiles).
• Database & Models: Auto-generates Models, Repositories, DTOs, and Controllers from your schema configuration.
• Authentication & Security: Supports generating endpoints and logic for JWT authentication, Email/Password login, Social Login (OAuth), and Web auth.
• RBAC (Role-Based Access Control): Completely scaffolded authorization logic.
• Real-time & Communication: Built-in generators for WebSockets (chat), IMAP (email integration), and Notifications.
• Client Generation: Need to interact with your API? Generate a complete client API SDK.
• AI-Assisted Configuration: Use the included AI_YML_GENERATOR_PROMPT.md to have an LLM automatically write complex master_config.yaml files for your domain.

📋 Prerequisites

• Python 3.8+
• Go 1.20+ (For compiling and running the generated application)
• Optional: Docker (if you want to build and deploy via containers)

🛠️ Installation & Setup

1. Install from PyPI (Recommended):

   pip install gofiber-generator
   

2. Or install locally for development:

   pip install -e .
   

---

🏁 Quickstart

Once installed, the gofiber-gen command is available globally.

1. Review/Edit your configuration: Open master_config.yaml and define your project's models, routes, and settings.

2. Run the generator:

   gofiber-gen --config master_config.yaml --output ./generated
   

3. Format the generated Go code:

   # Formatter is also available via the package
   python -m generators.format_generated_code ./generated
   

4. Run your new Go backend:

   cd generated
   go mod tidy
   go run ./cmd/server/main.go
   # Or using the generated makefile: make run

🧰 Individual Generators

You don't have to generate the entire project at once. The system is modular, allowing you to update specific components individually. All generators typically accept --config, --templates (pointing to ./tool/templates), and --output.

• App Scaffold (app_generate.py)
  Generates configuration loaders, database setup, caching architecture, and fundamental structure.

• Models, Repositories, DTOs & Controllers (repo_model_config_generate.py)
  The backbone of your domain logic. Maps YAML schema to Go structs and generates REST endpoints.

• Authentication (auth_generate.py)
  Generates authentication routes, middleware, and credential processing logic.

• Role-Based Access Control (rbac_generate.py)
  Generates roles, permission mappings, and access enforcement code logic.

• WebSockets & Chat (chat_websocket_genrator.py)
  Scaffolds WebSocket handlers and connections for real-time messaging.

• Routes & Documentation (routes.py)
  Consolidates API endpoints from your configs and generates a structured view or routing file.

• Client API Generator (api_client_generator.py)
  Generates frontend-ready SDKs (like Flutter API clients) based on the current backend specification.

🖥️ Native GUI Builder

If you prefer a visual approach over the CLI, run the built-in GUI configuration and generation tool:

python native_vifber_gui.py

This tool provides a user-friendly way to validate configs and trigger specific Python generation scripts visually.

---

🗂️ Templates and Customization

The Go files are generated using Jinja2 templates located in the tool/templates/ directory.

• To change the pattern of generated handlers, edit tool/templates/pkg/controller/controller.go.j2.
• To adjust infrastructure (Docker, Makefile), edit tool/templates/infra/.
• Variables injected into these templates align exactly with the schema inside master_config.yaml.

---

🤝 Contributing

1. Extend or fix the Jinja2 templates inside tool/templates/.
2. Add new functionalities by creating a focused *_generate.py script and integrating it into generator.py.
3. If changing template structure requirements, update master_config.yaml to prevent breaking generation.
4. Keep the code generation decoupled and domain-agnostic.
