Treffer: Developing a communication layer between Python and JavaScript

The study focused on the development of a two-way communication system for Python and JavaScript programming languages in situations where JavaScript runtime responses to requests sent by Python runtime. The objective of the study was to create a socket-based communication module that facilitates interaction between a Python client and a JavaScript client, leveraging Flask as the server framework and SocketIO for communication. The study leveraged various methods to create the system and evaluate it. As a structure, class-based approach was introduced. For serialization, were used JSON, MessagePack and Numpy. Evaluation methods involved simulated request-response scenarios, latency measurements under different payload sizes with a manual logging method. Wireshark was used to capture network traffic and analyze it. As a result, a complete prototype was developed and tested. The system demonstrated reliable performance, even if there were certain improvement considerations, efficient data exchange with a combination of JSON and zstd, and stability under load, confirming its suitability for two-way communication between Python and JavaScript environments.
