In this poster, we present the programming style for dis- tributed applications using ScalaLoci1 [16]: The language allows a distributed program to be developed as a single code base generating the code specific to each component of the distributed system ś including communication code ś automatically during compilation (multitier approach). As a result, developers do not need to handle details like data conversion and network communication and can focus on the actual application logic. In ScalaLoci, data flow between the components of the distributed system is specified ex- plicitly (reactive approach). Events, e.g., network messages or user input, transfer data among hosts and trigger state changes or new events.
