Dependencies

This project depends on the following compile-time dependencies being installed:

• Java 8 (or greater)
• Gradle 6.8.0 (or greater)

Testing

The simplest way to check if a websocket is available, is to perform a cURL via the command line:

curl \
  --include \
  --no-buffer \
  --header 'Connection: Upgrade' \
  --header 'Upgrade: websocket' \
  --header 'Sec-WebSocket-Key: SGVsbG8sIHdvcmxkIQ==' \
  --header 'Sec-WebSocket-Version: 13' \
  http://localhost:10101/socket

The expected response is an upgraded connection:

HTTP/1.1 101 
Upgrade: websocket
Connection: upgrade
Sec-WebSocket-Accept: qGEgH3En71di5rrssAZTmtRTyFk=
