feat(serve): keep command palette search across re-opens - #1836
Conversation
The dev UI command palette now remembers the search text when closing, so refining a query no longer means retyping it — useful when working across many templates. The query is only cleared when an actual command runs; selecting a template or dismissing the palette keeps it. - CommandInput syncs a preset value into the filter on open (immediate) - Command re-filters when items register, so a restored query isn't stuck on "no results" before the template items mount
📝 WalkthroughWalkthroughThe command palette now preserves searches when it closes, restores searches after template navigation, and clears them for selected actions. Filtering also reruns when registered items change, while external input values synchronize immediately. ChangesCommand palette search behavior
Estimated code review effort: 3 (Moderate) | ~15 minutes Merge Risk: 🔵 Low · up to The command palette may occasionally display stale search results when one item is replaced by another without changing the total item count; the PR is otherwise mergeable with owner awareness and follow-up for this bounded correctness issue.

Vue 3 watch reactive Map size delete set same tick callback deep true behavior
💡 Result:
In Vue 3, the reactivity system handles Map mutations (such as set, delete, and clear) by triggering effects tracked during access. When using watch on a reactive Map, the behavior depends on whether you are watching the collection itself or a specific value. Reactivity and Mutations Vue 3's reactive wraps Map objects in a Proxy. This proxy intercepts operations like.set,.delete, and.clear to trigger updates for any effects currently tracking the Map's contents [1]. Watch Behavior 1. Watching the Map itself: When you pass the reactive Map directly to watch, it is implicitly treated as a deep watcher [2][3]. This means the callback will trigger when items are added, deleted, or updated (set) [1][4]. 2. Watching a specific key: If you watch a getter, such as => myMap.get('key'), the watcher will only trigger if the value associated with that specific key changes [1]. Size Tracking and Updates A common point of confusion is whether operations that do not change the Map's size (like overwriting an existing key) trigger updates. - Traditionally, Vue 3 reactivity treats these as triggers to ensure data consistency for iterators [5]. - While internal discussions and refinements (such as PR #7328) have aimed to optimize the reactivity system to avoid unnecessary triggers on.set operations for existing keys, the primary mechanism remains that reactive collections track mutations to ensure watchers and computed properties react reliably [5][6]. Same-Tick Callback Execution Vue watchers by default use pre-flush timing (before component updates) [3]. If you perform multiple mutations (e.g., a set followed by a delete) within the same synchronous tick, the reactivity system batches these operations. Consequently, the watch callback typically executes once per tick, reflecting the final state, unless flush: 'sync' is explicitly set in the watch options [3]. Summary of Key Points - Deep Watch: Watching a reactive Map directly triggers on all mutations (set/delete/clear) [4][3]. - Mutation Tracking: Vue tracks collection mutations to keep UI and computed properties in sync [1]. - Performance: Because Map watchers are inherently deep, they may have performance implications on very large collections; use them only when necessary [2]. - Same-Tick Behavior: Multiple mutations to the same Map in one tick are batched, and the watcher will trigger based on the Vue flush timing configuration (defaulting to 'pre') [3].

Track allItems mutations, not only its size.
If one item is deleted and another is added in the same tick, allItems.value.size has the same old and new value. The watcher can skip filterItems(), which leaves filterState.filtered stale. Watch allItems deeply or maintain a mutation revision. Add a same-size replacement test.

What
The dev-server command palette now remembers the search text when you close it, so refining a query means editing what's there instead of retyping from scratch — handy when working across many templates.
Clearing rules:
Why
When building lots of emails you often reopen the palette to tweak the same search. Previously it reset to empty on every close, forcing a full retype.
How
App.vue— the search persists by default; clearing is driven by which handler runs (command handlers callcloseCommandPalette(true); template navigation restores the query after the palette's select-reset).CommandInput.vue— the externalv-model→ internal filter sync is nowimmediate, so a restored value actually populates the filter when the palette re-opens.Command.vue—filterItemsnow re-runs when the item set changes, not only on search change. A restored query is applied once on open, before the template items register; without this it stayed stuck on "No results found" even though the item existed.Verified
