What should the front end part of an applications technical design represent and consider? With back end, there's the database schema, API endpoints, flow charts for processes. But with the front end, only recently has it become somewhat data heavy. What do you do when asked to submit a technical design as a front end engineer? For reference, at my employment design is a large part of being a senior developer, so I have to do something, I'm not sure what though, and have not been successful in finding examples online.
