Fiber with Dependency Injection (via Parsley)

This example demonstrates integrating the Parsley dependency injection framework into a GoFiber web application. The goal is to showcase how dependency injection can create a clean, maintainable, and modular structure in your GoFiber projects.

Overview

In this example, we use Parsley to:

• Bootstrap the Application: Set up and configure the Fiber app using Parsley’s DI container.
• Register Dependencies: Define and register services and route handlers with the DI container.
• Resolve Dependencies: Automatically resolve and inject them where needed.

Key Features

• Modular Configuration: Services are registered in modules, allowing for a clean separation of concerns.
• Automatic Dependency Injection: Constructor-based dependency injection wire services together.
• Simplified Route Management: Route handlers are registered and managed via the DI container, making it easy to extend and maintain.

How It Works

• The main function bootstraps the application using Parsley’s RunParsleyApplication function.
• Modules define how services (such as the Fiber app and route handlers) are registered and configured.
• Route handlers are implemented as services that receive their dependencies (like the Greeter service) via constructor injection. The Greeter service is a simple example of how services can be injected and used within route handlers to handle HTTP requests.

Running the Example

To run this example:

• Clone the repository and navigate to the example directory.
• Run go run main.go to start the application.
• Access the application by navigating to http://localhost:5502/say-hello?name=YourName. This will return a greeting message, demonstrating the integration of Parsley with GoFiber.
