Babl is a high-performance, scalable web-socket server designed for use in low-latency applications.
Built from the ground up to provide blazing fast execution speeds, Babl will comfortably handle high throughput, large session-count workloads without slowing down.
Using an event-driven reactive programming model, your application code is executed in an allocation-free, lock-free event-loop for maximum efficiency and mechanical sympathy.
Babl is a container for your application, providing a high-performance proxy for web-socket connections.
Your application will be notified of connection lifecycle events (
onDisconnect), and receive
onMessage) from client connections.
Your application will publish responses to inbound messages, which will be sent back to the client.
For more information, see Application.

Babl is packaged in a
docker container for ease of deployment. The base container is tagged as
"aitusoftware/babl:latest" for the latest released image),
and should be extended with your own container definition:
FROM aitusoftware/babl:latest COPY my-app/build/lib/ /babl/lib/ COPY my-app/build/config/my-app.properties /babl/config ENV BABL_CONFIG_FILE="/babl/config/my-app.properties" ENV JVM_RUNTIME_PARAMETERS="-Dbabl.debug.enabled=true"
The project source code contains an example
docker-compose file that creates a simple echo application with HTML
resources hosted by an
Babl can also be used in a standalone manner. Simply download the
-all variant of the JAR from
the releases page, and execute the following:
$ java -jar /path/to/babl-all-0.5.0.jar /path/to/config.properties
Note that there is no legacy HTTP server functionality, so any HTML resources will need to be hosted using a suitable technology.
