Functions ¶

func Echo ¶

func Echo(conn *websocket.Conn, ctx context.Context)

Echo is a built-in handler that reads messages and echoes them back.

func Upgrader ¶

func Upgrader(handler Handler, opts *Options) gin.HandlerFunc

Upgrader returns a gin.HandlerFunc that upgrades the HTTP connection to WebSocket and delegates to the provided handler. If opts is nil, all origins are accepted (InsecureSkipVerify = true).

Types ¶

type Client ¶

type Client struct {
	ID   string
	Conn *websocket.Conn
	// contains filtered or unexported fields
}

Client represents a single WebSocket connection registered with a Hub.

type Handler ¶

type Handler func(conn *websocket.Conn, ctx context.Context)

Handler is a callback for handling a WebSocket connection.

type Hub ¶

type Hub struct {
	// contains filtered or unexported fields
}

Hub manages WebSocket clients and rooms.

func NewHub ¶

func NewHub() *Hub

NewHub creates an empty Hub with initialized maps.

func (*Hub) Broadcast ¶

func (h *Hub) Broadcast(room string, msgType websocket.MessageType, data []byte)

Broadcast sends a message to all clients in the named room.

func (*Hub) BroadcastOthers ¶

func (h *Hub) BroadcastOthers(room string, sender *Client, msgType websocket.MessageType, data []byte)

BroadcastOthers sends a message to all clients in the named room except the sender.

func (*Hub) Clients ¶

func (h *Hub) Clients(room string) []*Client

Clients returns a snapshot of all clients in the named room. Returns nil if the room does not exist.

func (*Hub) Handler ¶

func (h *Hub) Handler(onConnect func(*Client)) gin.HandlerFunc

Handler returns a gin.HandlerFunc that upgrades the HTTP connection to WebSocket, creates a Client, registers it with the Hub, and calls onConnect. The client is automatically removed when onConnect returns.

func (*Hub) Join ¶

func (h *Hub) Join(client *Client, room string)

Join adds the client to the named room. The room is created if it does not exist. Joining the same room twice is a no-op.

func (h *Hub) Rooms() []string

Rooms returns a snapshot of all active room names.

func (*Hub) Send ¶

func (h *Hub) Send(clientID string, msgType websocket.MessageType, data []byte) error

Send delivers a message to a single client by ID. Returns an error if the client is not found.

type Options ¶

	OriginPatterns     []string // Allowed origin patterns for CORS
	InsecureSkipVerify bool     // Skip origin verification (dev only)
}
