A Vue application can be correct at the component level and still show the wrong case after a request race, an index-key reorder, or a server/client state mismatch. This track ties reactive derivation, watcher cleanup, component ownership, and request-scoped server state into one review queue. Each lesson states the data owner and the event that ends its lifetime.
Topics in this track
- Vue Source State, Computed Views, and Large Snapshots — Keep one reactive source of truth, derive views with computed values, and bound large immutable data costs.
- Vue Watch Cleanup and Stale Request Ownership — Attach each fetch to the watched identity and cancel or reject work when that identity changes.
- Vue Props, Emits, and Keyed Editor Ownership — Keep parent-owned records immutable to children and make draft lifetime follow a case identity.
- Vue Server Rendering and Hydration Stability — Keep per-request state isolated and make the first browser render agree with server HTML.
