How do I paginate results with Fiber in Go?

Pagination is a common requirement for web applications to efficiently display large sets of data in manageable chunks. This example demonstrates how to implement pagination using the Fiber framework in Go.


    package main

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

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

        app.Get("/items", func(c *fiber.Ctx) error {
            // Sample data
            items := make([]string, 100) // Simulating 100 data items
            for i := 0; i < 100; i++ {
                items[i] = "Item " + strconv.Itoa(i+1)
            }

            // Pagination parameters
            page, _ := strconv.Atoi(c.Query("page", "1"))
            limit, _ := strconv.Atoi(c.Query("limit", "10"))
            offset := (page - 1) * limit

            // Calculate total pages
            total := len(items)
            totalPages := int(math.Ceil(float64(total) / float64(limit)))

            // Create paged items
            if offset > total {
                return c.Status(404).SendString("Page not found")
            }
            end := offset + limit
            if end > total {
                end = total
            }

            return c.JSON(fiber.Map{
                "page":        page,
                "total":       total,
                "totalPages":  totalPages,
                "items":       items[offset:end],
            })
        })

        app.Listen(":3000")
    }
