minor fix: do not update meta tracker timestamp if value does not change#61
Conversation
This logic is implemented within the updateMetTracker, so does not need to be repeated. New behavior: - if `updateTime` is set to false, the timestamp will never update, as expected - if `updateTime` is set to true, the timestamp will only update if the latest value actually differs from the current value - if no value is provided for `updateTime`, true is assumed and above logic is used

18-26: Potential edge case in value parsing logic.While the function handles the case where
countmight be undefined using the nullish coalescing operator, there's a subtle issue with the formatting whentestUpdateis true.Consider adding a check to ensure consistent formatting regardless of whether the input already contains a period:
function updateVal(testUpdate: boolean) { setValue("planet", (v) => { - const [base, count] = v.split(".") + const parts = v.split(".") + const base = parts[0] || BASE_DEFAULT + const count = parts[1] const recoveredNum = Number(count ?? 0) const safeNum = Number.isNaN(recoveredNum) ? 0 : recoveredNum const BASE_DEFAULT = "Jupiter" - return testUpdate ? `${base || BASE_DEFAULT}.${safeNum + 1}` : v + return testUpdate ? `${base}.${safeNum + 1}` : v }) }Also, consider moving the
BASE_DEFAULTdeclaration before its usage to avoid potential reference errors.

1-1: Good addition ofisEqualfrom lodash-es.The addition of
isEqualis necessary for the deep comparison of raw values implemented in this PR.
43-44: Excellent optimization to prevent unnecessary timestamp updates.The new logic correctly determines if a value has actually changed before updating the timestamp. This directly addresses the PR objective by preventing metadata timestamp updates when values don't change.
The variable naming is clear and the condition handles both the null
basePathcase and the value comparison case properly.
46-46: Smart reuse of existing or new timestamp.This implementation maintains backward compatibility with the existing
updateTimeparameter while implementing the optimization. The conditional use ofnewTimeorlastKnownTimeensures timestamps are only updated when necessary.playground/app.vue (4)
8-8: Good use ofsetValuedestructuring.Correctly added
setValueto the destructured values fromuseForm, which is necessary for the programmatic update functionality added in this PR.
15-15: Nice addition of reactive state for UI control.The
hideInputref is appropriately used to control the visibility of the input element, showcasing the conditional rendering capabilities of Vue.
34-35: Good conditional rendering implementation.The v-if directive is properly used to control the visibility of the input field based on the reactive state.
42-48: Excellent UI controls for testing functionality.The toggle button and update button provide a simple way to test both the conditional rendering and the metadata timestamp optimization implemented in this PR.

137-143: Helpful documentation for future integration.The comments clearly explain the pending integration with Vue.js core, providing context for why certain type definitions are maintained in their current form.
145-146: Good generalization of directive modifiers.Changing from specific literal types to the more generic
stringtype makes the directives more flexible and future-proof.
151-158: Clear documentation about pending Vue.js core integration.The comments provide good context about the relationship with upstream Vue.js changes.
160-166: Consistent generalization of directive modifiers.The change to use the generic
stringtype is consistently applied across all relevant directive types.

I also loosened the v-register directive modifier types for now, waiting on fix(types): the directive's modifiers should be optional #12605 in vuejs/core to eventually end up in a vue release to then re-introduce the relevant level of type-safety for the modifiers. |
