api := app.Group("/api")
api.Get("/users", handler)

func (*Group) Head 

func (grp *Group) Head(path string, handlers ...Handler) Router

func (*Group) Static 

func (grp *Group) Static(prefix, root string, config ...Static) Router

Static will create a file server serving static files

func (*Group) Trace 

func (grp *Group) Trace(path string, handlers ...Handler) Router

     return c.Next()

type Map 

type Map map[string]interface{}

Map is a shortcut for map[string]interface{}, useful for JSON returns

	Type   string
	Ranges []struct {
		Start int
		End   int
	}

type Route 

type Route struct {

	// Public fields
	Method   string    `json:"method"` // HTTP method
	Path     string    `json:"path"`   // Original registered route path
	Params   []string  `json:"params"` // Case sensitive param keys
	Handlers []Handler `json:"-"`      // Ctx handlers
	// contains filtered or unexported fields
}

Route is a struct that holds all metadata for each registered handler

type Router 

type Router interface {
	Use(args ...interface{}) Router

	Get(path string, handlers ...Handler) Router
	Head(path string, handlers ...Handler) Router
	Post(path string, handlers ...Handler) Router
	Put(path string, handlers ...Handler) Router

}

Router defines all router handle interface includes app and group router.

type Static 

type Static struct {
	// When set to true, the server tries minimizing CPU usage by caching compressed files.
	// This works differently than the github.com/gofiber/compression middleware.
	// Optional. Default value false
