Please, try this:

r := gin.New()
r.GET("/ws", func(c *gin.Context) {
    handler := websocket.Handler(EchoServer)
    handler.ServeHTTP(c.Writer, c.Req)
})
r.Run(":8080")

@manucorporat , after last update i try:

r := gin.New()
r.GET("/ws", func(c *gin.Context) {
    handler := websocket.Handler(EchoServer)
    handler.ServeHTTP(c.Writer, c.Req)
})
r.Run(":8080")

I have added the .Hijack() method and an example in my working fork as part of #16, but due to some differences in practice my fork has become incompatible.

I don't want to double the work/headache for myself or the repo maintainer so I won't be making another fork to submit another pull request over a renamed function or two.

If you wanna dig in, look here:

The relevant parts are in:
