TypeScript is a logical pick for a frontend focused openEHR development. I picked Dart for my tools which is less logical 
(unless Flutter is used for the frontend)
Last year I started porting my tools to TypeScript: TypeScript library for AM / RM / OPTs
What is your approach? Did you use the OpenAPI generator or do you write your tools by hand? I know @gmickel is a great fan of AI coding. Were you successful using AI agents to write your tools?
