Episode notes
Prefer Server-Side Feature Flags
- Use server-side feature flags to prevent UI layout shifts and improve performance.
- Keep flag evaluation on the server and avoid leaking sensitive flags to the client.
Edge For Assets, Origin For Data
- Place feature flag logic near your data origin for correctness rather than solely at the edge.
- Use the edge for static assets and routing, and keep data next to compute at origin.
Empower Small Teams With Ownership
- Empower small founder-led teams with autonomy and clear ownership to ship impactful products.
- Give budgets and metrics ownership so teams can iterate fast and measure success.
