Ignition uses the jetty libraries to run its webserver and provide its HTTP(s) clients. That includes websocket support.

Start with Jetty's [Programming Guide](https://www.eclipse.org/jetty/documentation/jetty-11/programming-guide/index.html).

However, you will need to adjust for the version of Jetty provided by Ignition, which is v9.4. So use [these javadocs](https://www.eclipse.org/jetty/javadoc/jetty-9/index.html) instead of the v11 javadocs.

Edit: Hmmm. ~~It appears that Ignition _ **does not** _ package Jetty's websocket client library. You may need to use Java 11's native support:~~

[https://docs.oracle.com/en/java/javase/11/docs/api/java.net.http/java/net/http/package-summary.html](https://docs.oracle.com/en/java/javase/11/docs/api/java.net.http/java/net/http/package-summary.html)

Good luck. And report back, please. (:

Edit2: Paul corrected me. Jetty's websocket is bundled after all.
