This commit upgrades TypeScript to the latest version 5.3 and introduces
`verbatimModuleSyntax` in line with the official Vue guide
recommendatinos (vuejs/docs#2592).
By enforcing `import type` for type-only imports, this commit improves
code clarity and supports tooling optimization, ensuring imports are
only bundled when necessary for runtime.
Changes:
- Bump TypeScript to 5.3.3 across the project.
- Adjust import statements to utilize `import type` where applicable,
promoting cleaner and more efficient code.
This commit changes `WatchSource` signatures into `Readonly<Ref>`s.
It provides two important benefits:
1. Eliminates the possibility of `undefined` states, that's result of
using `WatchSource`s. This previously required additional null checks.
By using `Readonly<Ref>`, the state handling becomes simpler and less
susceptible to null errors.
2. Optimizes performance by using references:
- Avoids the reactive layer of `computed` references when not needed.
- The `watch` syntax, such as `watch(() => ref.value)`, can introduce
side effects. For example, it does not account for `triggerRef` in
scenarios where the value remains unchanged, preventing the watcher
from running (vuejs/core#9579).
- Replace `ref`s with `shallowRef` when deep reactivity is not needed.
- Replace `readonly`s with `shallowReadonly` where the goal is to only
prevent `.value` mutation.
- Remove redundant `ref` in `SizeObserver.vue`.
- Remove redundant nested `ref` in `TooltipWrapper.vue`.
- Remove redundant `events` export from `UseCollectionState.ts`.
- Remove redundant `computed` from `UseCollectionState.ts`.
- Remove `timestamp` from `TreeViewFilterEvent` that becomes unnecessary
after using `shallowRef`.
- Add missing unit tests for `UseTreeViewFilterEvent`.
- Add missing stub for `FilterChangeDetails`.
This commit fixes an issue where the check state of categories was lost
when toggling between card and tree views. This is solved by immediately
emitting node state changes for all nodes. This ensures consistent view
transitions without any loss of node state information.
Furthermore, this commit includes added unit tests for the modified code
sections.
