• test-driven-learning

  1 0 10.0 Java

  Learning tests

One approach I do not think many consider is starting with the Netty, which is used by many frameworks. We ended up using this for our current product, and while this gives the ultimate flexibility in handling requests it also heightens the bar somewhat for the ones employing its use, as it just gives you the nuts and bolts and it is up to you to make it play nice for your use-cases. I had to write quite a few learning tests to grok it.

• avaje-jex

  3 20 4.7 Java

  Web routing for Jetty, Grizzly, JDK Http server

  

I created https://github.com/avaje/avaje-jex ... with the hope of helping to move Javalin more in the Java direction but yeah, Javalin isn't going in that direction. So avaje-jex now will follow it's own path (as pretty much a web routing layer that abstracts over various http servers like jetty, grizzly etc with a java and loom focus).
