Bidirectional echo streams via webtransport-go never end

webtransport-go readable never ends

Starts a webtransport-go echo server on port 12345.

The server accepts incoming WebTransport sessions, waits for a bidirectional stream to be opened on the session and pipes it back to itself.

The client connects to the server, opens a bidirectional stream, writes a single message to the writable before closing it, then reads from the readable until it ends.

The readable stream never ends.

Usage

Clone this repo then:

• Install go1.20 or later
• Install go deps with go get

Node.js

• Paste the JS code into a https://codepen.io/pen/?editors=0012 or otherwise run it in a browser
• Ensure the browser console is visible
• See the browser output:

"CLIENT create session"
"CLIENT wait for session"
"CLIENT session ready"
"CLIENT create bidi stream"
"CLIENT get writer"
"CLIENT wait for writer"
"CLIENT write"
"CLIENT close writer"
"CLIENT read from stream"
"CLIENT got from stream" // [object Object]
{
  "done": false,
  "value": {
    "0": 0,
    "1": 1,
    "2": 2,
    "3": 3
  }
}
"CLIENT read from stream"

The readable end of the stream never ends. If it did, you'd see these extra lines at the end:

//..other output
    "2": 2,
    "3": 3
  }
}
"CLIENT read from stream"
"CLIENT got from stream" // [object Object]
"CLIENT read stream finished"
