👽Go API

This project is a simple book inventory management API implemented in Go using the Gin web framework. It provides basic functionalities such as retrieving a list of books, retrieving a specific book by ID, creating a new book entry, checking out a book (decreasing its quantity), and returning a book (increasing its quantity). The data is stored in memory as a static list of books.

Project Structure

• main.go: Contains the main application logic, including the setup of the Gin router and the implementation of CRUD operations for the book inventory.

API Endpoints

1. GET /books: Retrieve a list of all books.

2. GET /books/:id: Retrieve details of a specific book by ID.

3. POST /books: Create a new book entry.

4. PATCH /checkout: Check out a book by decreasing its quantity (Query parameter style).

5. PATCH /return: Return a book by increasing its quantity (Query parameter style).

Book Structure

• Each book has an ID, Title, Author, and Quantity.

  type Book struct {
    ID       string `json:"id"`
    Title    string `json:"title"`
    Author   string `json:"author"`
    Quantity int    `json:"quantity"`
  }

How to Run

1. Ensure you have Go installed on your machine.
2. Run the following command to install the required dependencies:

go get -u github.com/gin-gonic/gin

Execute the main.go file to start the server:

go run main.go

• Access the API at http://localhost:8080.

API Usage

Use tools like curl or Postman to interact with the API endpoints. Example: To check out a book, send a PATCH request to http://localhost:8080/checkout?id=<book_id>.

Note

This is a simple demonstration project, and it uses in-memory data storage. For a production scenario, consider using a database for persistent data storage.
