A local architecture pack that turns React learning resources into system-design language for real interview use.

Frontend System DesignReact.jsFrontend Breadth
Easy start

Learn it in plain school-level language first

  • Frontend design means deciding who owns data and how screens talk to each other.
  • Keep state near the place that truly owns it, then move it up only when needed.
  • A strong design answer covers loading, errors, performance, and accessibility too.

What this local pack helps you answer

State ownership, screen decomposition, shared data flow, and explaining how to structure medium-to-large React applications.

Why this matters for your profile

You already have hands-on product experience, so system design rounds are less about syntax and more about showing calm structure and good boundaries.

Quick revision

Fast last-day recap

  • Users and screens first.
  • State follows ownership.
  • Boundaries beat tool lists.
  • Include loading, error, performance, and accessibility.
Key takeaways

Local study notes

  • Start architecture answers with user flows and screen responsibilities before discussing tools.
  • State should live close to ownership and move upward only when multiple consumers truly need it.
  • Shared UI patterns become easier to scale when component responsibilities are explicit and reusable.
  • Architecture decisions should cover loading, error states, performance, and accessibility from the start.
