Research direction

Start with the “A simplified echo SockJS server” sample in the README and reproduce the TypeError. Compare the sample with the attach() definition linked in lib/server.js, then verify that the corrected sample runs without the error.

Description

I just use the sample code, "A simplified echo SockJS server" on readme, but I got the error message

echo.attach(server);
     ^

TypeError: echo.attach is not a function

But I see attach() does exist at https://github.com/sockjs/sockjs-node/blob/main/lib/server.js#L58 so I can't figure out why.
