1. A computer-implemented method comprising: determining, by a computer-based system for generating computer-executable code for a message flow in a message queuing infrastructure, a type of the message flow; determining, by the computer-based system, message flow parameters; selecting, by the computer-based, system and based on the type of message flow, a design pattern, wherein the design pattern decouples a service requesting component and a service-providing component; and generating, by the computer-based system, a computer-executable script comprised of multiple nodes for the message flow based on the type of the message flow, the message flow parameters, and the design pattern.
