Announcing Precomputed Reachability Analysis in Socket
Socket’s precomputed reachability slashes false positives by flagging up to 80% of vulnerabilities as irrelevant, with no setup and instant results.
github.com/gofiber/websocket/v2
Based on Fasthttp WebSocket for Fiber with available *fiber.Ctx
methods like Locals, Params, Query and Cookies.

package main

func main() {
app := fiber.New()
app.Use("/ws", func(c *fiber.Ctx) error {
// IsWebSocketUpgrade returns true if the client
// requested upgrade to the WebSocket protocol.
if websocket.IsWebSocketUpgrade(c) {
c.Locals("allowed", true)
return c.Next()
}

app.Get("/ws/:id", websocket.New(func(c *websocket.Conn) {
// c.Locals is added to the *websocket.Conn
log.Println(c.Locals("allowed")) // true
log.Println(c.Params("id")) // 123
log.Println(c.Query("v")) // 1.0
log.Println(c.Cookies("session")) // ""
// websocket.Conn bindings https://pkg.go.dev/github.com/fasthttp/websocket?tab=doc#pkg-index
var (
mt int
msg []byte
err error
)
for {
if mt, msg, err = c.ReadMessage(); err != nil {
log.Println("read:", err)
break
}
log.Printf("recv: %s", msg)
if err = c.WriteMessage(mt, msg); err != nil {
log.Println("write:", err)

}))
log.Fatal(app.Listen(":3000"))
// Access the websocket server: ws://localhost:3000/ws/123?v=1.0

}
If you get the error websocket: bad handshake
when using the cache middleware, please use config.Next
to skip websocket path.
app := fiber.New()
app.Use(cache.New(cache.Config{
Next: func(c *fiber.Ctx) bool {
return strings.Contains(c.Route().Path, "/ws")
},
}))
app.Get("/ws/:id", websocket.New(func(c *websocket.Conn) {}))
