Deep Dive: Memory Leak Detection and Prevention in Vue 3 SPAs

Memory leaks in Vue usually stem from uncleaned global event listeners, timers, or dangling references in EffectScopes.

While Vue's reactivity system handles most cleanup, leaks occur when logic 'escapes' the component lifecycle. Examples include adding window.addEventListener without a corresponding removeEventListener in onUnmounted, or creating a setInterval that keeps a reference to a component's proxy. Using effectScope manually outside components requires explicit .stop() calls to release refs and computed values.
