I have implemented an EDI (for invoicing) system from scratch in Node.js/ NestJs and integrated it into our enterprise-grade system. I wonder if there is a job market for this to work as a software engineer specialized in the development of EDIFACT systems for enterprise-grade systems. I know that there are a lot of tools to build and map the EDI data fields, but I am not speaking of using these vendor tools like IBM Sterling; I am exclusively referring to implementing the EDIFACT standards from scratch, the EDI file generation, validation, and parsing. Is this a thing? I couldn't even find any libraries to help me generate or parse the EDI files in Node.js, so I had to implement everything from scratch.
