# ng-blog Backend

This is the backend service for the ng-blog project. It's written in Go and provides the API endpoints for the frontend application.

## Getting Started

### Prerequisites

- Go (version 1.24 or higher)

### Running the Backend

The backend provides two main commands: `serve` and `help`.

- **`serve`**: Starts the backend server. It loads configuration from environment variables and listens for incoming requests.

  ```bash
  go run ./cmd/main.go serve
  ```

- **`help`**: Displays usage information about the configuration options.

  ```bash
  go run ./cmd/main.go help
  ```

### Configuration

The backend is configured using environment variables. The `help` command will display the available configuration options. The configuration is loaded using the `go-simpler.org/env` library. Environment variable names are expected to be in the format `CONFIG_OPTION_NAME`.

## Directory Structure

- `cmd/main.go`: The main entry point for the application. Handles command-line arguments and starts the server.
- `internal/config`: Defines the configuration struct and default values.
- `internal/startup`: Responsible for initializing the HTTP multiplexer and other startup tasks.
