echo

For echo v5.

bash

go get go.chanx.dev/adapters/echo

func Echo(engine *chanx.Engine) *echo.Echo {
	e := echo.New()
	auth := func(next echo.HandlerFunc) echo.HandlerFunc {
		return func(c *echo.Context) error {
			c.Set("user", c.Request().Header.Get("X-User")) // read by chanx.UserFrom("user")
			return next(c)
		}
	}
	chanxecho.Mount(e.Group("", auth), engine) // "/ws/chat/:room"
	chanxecho.MountDocs(e, engine, "/asyncapi", asyncapi.Info{Title: "Chat"})
	return e
}

engine.Handle("/ws/chat/{room}", ChatConsumer{}, chanx.UserFrom("user"))

Routes, groups and middleware are echo's. {room} is registered as :room.
Middleware runs before the upgrade. A value it stores with c.Set("user", u) is the connection's user through chanx.UserFrom("user"). An error it returns goes through echo's HTTPErrorHandler, and no socket is opened.
The client IP is c.RealIP(), so echo's IPExtractor applies.
Docs: chanxecho.MountDocs serves /asyncapi, .json and .yaml.

chanxecho.Mount and chanxecho.Handler take an optional Accept function replacing the default coder/websocket upgrade. Shut down with engine.Shutdown(ctx) as well as echo's.

Next: Fiber.
