Reactive Flows is a demo project showing a Reactive web app built with:
Akka Actors
Akka HTTP
Akka SSE (server-sent events)
Akka Distributed Data
Akka Cluster Sharding
Akka Persistence
AngularJS
Cassandra
Scala
etcd
Usage
Important: Reactive Flows makes use of server-sent events and advanced JavaScript which aren't available for all browsers, so make sure to use Firefox > 25.0, Safari > 7.1 or Chrome > 45.0
To run a single node, simply execute reStart in an sbt session; you can shutdown the app with reStop
To run multiple nodes, build a Docker image with docker:publishLocal and execute the script bin/run-reactive-flows.sh without an argument or a number from [0, 10)
As the names and labels of the flows aren't persisted, you have to create them after the app has started; see below examples
Important: Reactive Flows uses ConstructR for initializing the cluster; make sure etcd is started and available
Important: Reactive Flows uses the Cassandra plugin for Akka Persistence; make sure Cassandra is started and available under the configured contact point
Run in sbt
First start Cassandra and etcd:
docker-compose rm -f -s -v
docker-compose up -d etcd cassandra
