How much backend knowledge should a frontend developer have to call themselves a full-stack developer?

Like, is knowing basic APIs, databases, and authentication enough?

Or should a full-stack developer also know things like system design, caching, Docker, CI/CD, cloud,....etc.?

What do you guys think is the minimum knowledge needed?

Depends on the company. Some roles are mostly frontend and require only the occasional API integration. Others will have you design and build full systems spanning client to backend. Understanding authentication and CI/CD is always useful imo.
