System design (frontend)

Part of the Frontend Developer Roadmap.

Summary

Higher-level interview questions about architecting a frontend feature or app — component structure, state management choices, API design, scalability — common in senior interviews.

How to Learn This

  • 1Practice a mock frontend system design question, e.g. 'design a news feed'.
  • 2Structure your answer: requirements, component breakdown, state/data flow, trade-offs.
  • 3Study how a real product you use is likely architected, as a reference.
