What problem does it solve?
A practical, reference-driven guide for diagnosing and resolving Vue 3 runtime errors, warnings, async component failures, reactivity surprises, and SSR/hydration mismatches so developers can quickly pinpoint root causes and apply proven fixes.
Core Features & Use Cases
- Comprehensive troubleshooting checklist covering reactivity, computed and watch pitfalls, template refs, and lifecycle hook timing.
- Guidance for async components, Suspense, KeepAlive, and SSR-specific hazards including hydration mismatches and platform API usage.
- Best-practice recommendations (defineExpose, defineEmits placement, markRaw, nextTick, toRefs, stable keys) and performance tips for TransitionGroup and prop stability.
- Real-world scenarios: fixing duplicated mounts with KeepAlive, resolving v-if/v-for precedence issues, and preventing memory leaks from event listeners and transitions.
Quick Start
Analyze a failing Vue 3 runtime error and produce a prioritized debugging checklist that inspects reactivity sources, computed/watch dependencies, template ref timing, async component/Suspense behavior, and SSR/hydration differences.
