r := gin.Default()
r.GET("/", func(c *gin.Context) {
    page, _ := strconv.Atoi(c.DefaultQuery("page", "1"))
    limit, _ := strconv.Atoi(c.DefaultQuery("limit", "3"))
    var users []User

    paginatorr,err := paginator.Pagging(&paginator.Param{
        DB:      db,
        Page:    page,
        Limit:   limit,
        OrderBy: []string{"id desc"},
        ShowSQL: true,
    }, &users)
    if(err != nil){
        c.JSON(500, err)
    }
    c.JSON(200, paginatorr)
})

With Echo

e := echo.New()
e.GET("/", func(c echo.Context) error {
    page, err := strconv.Atoi(ctx.QueryParam("page"))
    if err != nil {
        page = 1
    }
    limit, err := strconv.Atoi(ctx.QueryParam("limit"))
    if err != nil {
        limit = 20
    }
    var users []User
    paginatorr, err := paginator.Paging(&paginator.Param{
        DB:      db,
        Page:    pageNumber,
        Limit:   limit,
        OrderBy: []string{"id desc"},
    }, &users)
