        package main

        import (
            "github.com/gofiber/fiber/v2"
        )

        func main() {
            app := fiber.New()

            // Create a simple struct for our item
            type Item struct {
                ID    string `json:"id"`
                Name  string `json:"name"`
                Price int    `json:"price"`
            }

            items := []Item{
                {ID: "1", Name: "Item One", Price: 100},
                {ID: "2", Name: "Item Two", Price: 200},
            }

            // GET all items
            app.Get("/items", func(c *fiber.Ctx) error {
                return c.JSON(items)
            })

            // POST a new item
            app.Post("/items", func(c *fiber.Ctx) error {
                var item Item
                if err := c.BodyParser(&item); err != nil {
                    return c.Status(400).SendString(err.Error())
                }
                items = append(items, item)
                return c.Status(201).JSON(item)
            })

            // Start the server
            app.Listen(":3000")
        }
