Functions

func FormatCloseMessage 

func FormatCloseMessage(closeCode int, text string) []byte

FormatCloseMessage formats closeCode and text as a WebSocket close message. An empty message is returned for code CloseNoStatusReceived.

func IsCloseError 

func IsCloseError(err error, codes ...int) bool

IsCloseError returns boolean indicating whether the error is a *CloseError with one of the specified codes.

func IsUnexpectedCloseError 

func IsUnexpectedCloseError(err error, expectedCodes ...int) bool

IsUnexpectedCloseError returns boolean indicating whether the error is a *CloseError with a code not in the list of expected codes.

func IsWebSocketUpgrade 

func IsWebSocketUpgrade(c *fiber.Ctx) bool

IsWebSocketUpgrade returns true if the client requested upgrade to the WebSocket protocol.

func JoinMessages 

func JoinMessages(c *websocket.Conn, term string) io.Reader

JoinMessages concatenates received messages to create a single io.Reader. The string term is appended to each message. The returned reader does not support concurrent calls to the Read method.

func NewWs 

func NewWs(handler func(*fiber.Ctx, *Conn), config ...WsCfg) fiber.Handler

NewWs returns a new `handler func(*Conn)` that upgrades a client to the websocket protocol, you can pass an optional config.

	// contains filtered or unexported fields
}

Conn https://godoc.org/github.com/gorilla/websocket#pkg-index

func (*Conn) Cookies 

func (conn *Conn) Cookies(key string, defaultValue ...string) string

Cookies is used for getting a cookie value by key Defaults to empty string "" if the cookie doesn't exist. If a default value is given, it will return that value if the cookie doesn't exist.

func (*Conn) Locals 

func (conn *Conn) Locals(key string) interface{}

Locals makes it possible to pass interface{} values under string keys scoped to the request and therefore available to all following routes that match the request.

func (*Conn) Params 

func (conn *Conn) Params(key string, defaultValue ...string) string

Params is used to get the route parameters. Defaults to empty string "" if the param doesn't exist. If a default value is given, it will return that value if the param doesn't exist.

func (*Conn) Query 

func (conn *Conn) Query(key string, defaultValue ...string) string

Query returns the query string parameter in the url. Defaults to empty string "" if the query doesn't exist. If a default value is given, it will return that value if the query doesn't exist.

type Ctx 

type Ctx = fiber.Ctx

type Route 

type Route = fiber.Route

type Router 

type Router = fiber.Router

type WsCfg 

type WsCfg struct {
	// Filter defines a function to skip middleware.
	// Optional. Default: nil
	Filter func(*fiber.Ctx) bool

	// HandshakeTimeout specifies the duration for the handshake to complete.
	HandshakeTimeout time.Duration

	// Subprotocols specifies the client's requested subprotocols.
	Subprotocols []string

	// Allowed Origin's based on the Origin header, this validate the request origin to
	// prevent cross-site request forgery. Everything is allowed if left empty.
	Origins []string

	// ReadBufferSize and WriteBufferSize specify I/O buffer sizes in bytes. If a buffer
	// size is zero, then a useful default size is used. The I/O buffer sizes
	// do not limit the size of the messages that can be sent or received.
	ReadBufferSize, WriteBufferSize int

	// EnableCompression specifies if the client should attempt to negotiate
	// per message compression (RFC 7692). Setting this value to true does not
	// guarantee that compression will be supported. Currently only "no context
	// takeover" modes are supported.
