# Go Book API Example

This is a simple Go web service that provides a basic API for retrieving book information. It's built using the `chi` router and serves hardcoded book data from memory.

## Project Structure

- `main.go`: Application entry point, sets up the HTTP server and defines the `/books/{id}` endpoint.
- `internal/handlers/book_handler.go`: Contains the `BookHandler` responsible for processing requests to the `/books/{id}` endpoint. It uses an in-memory list of books.
- `internal/models/book.go`: Defines the `Book` struct used to represent book data.

## Getting Started

### Prerequisites

- Go (version 1.16 or higher recommended)

### Running the Application

1. **Clone the repository:**
   ```bash
   git clone <repository_url>
   cd testing-go-example
   ```
   (Note: Replace `<repository_url>` with the actual repository URL if this project were hosted.)

2. **Run the server:**
   ```bash
   go run main.go
   ```
   The server will start on `http://localhost:3000`.

### API Endpoints

#### `GET /books/{id}`

Retrieves details for a single book by its ID.

**Example Request:**

```bash
curl http://localhost:3000/books/1
```

**Example Response:**

```json
{
  "id": "1",
  "title": "The Hitchhiker's Guide to the Galaxy",
  "author": "Douglas Adams"
}
```

```bash
curl http://localhost:3000/books/2
```

**Example Response:**

```json
{
  "id": "2",
  "title": "The Restaurant at the End of the Universe",
  "author": "Douglas Adams"
}
```
