i need a angular or react bpmn library with typescript and rest api service not xml or any thing else. also dont wana pars xml to json.
search a lot about that but I see lot of limitations and cant find bpmn library with json service.
i need to make a workflow like this with react or angular that communicate via json with back-end and typescript ready.

You could use NestJS and bpmn-engine together. These are server-side technologies.
I don't think you'll find an angular or react library that does this, because these are primarily client-side view rendering libraries.
