Walkthrough

The changes include a behavioral modification to element duration time calculation logic and stylistic refactoring of filter predicates across two Vue components. The container module now defaults to a 50ms delay and short-circuits when elements are not found, while application and template center modules adopt the more explicit Boolean() function for truthiness checks.

Changes

Cohort / File(s)	Summary
Element Duration Logic packages/canvas/container/src/container.ts	Modified getElementDurationTime to initialize delayTime to 50 instead of 0 and return early when the targeted element is not found, changing the computed wait time behavior for missing elements.
Filter Predicate Refactoring packages/workspace/application-center/src/Main.vue, packages/workspace/template-center/src/Main.vue	Updated filter predicates in getApplicationList and getTemplateList from !!value to Boolean(value) for functionally equivalent but more explicit truthiness checking.

Estimated code review effort

🎯 2 (Simple) | ⏱️ ~8 minutes

• The container.ts logic change introduces a new default value (50) and early-return behavior—verify that the 50ms default is appropriate for the missing-element use case and that the short-circuit doesn't skip necessary fallback logic.
• The Vue component changes are straightforward cosmetic refactoring with no behavioral impact.

Poem

🐰 A bunny hops through code so neat,
With fifty milliseconds sweet,
And Boolean makes truth clear,
No more double-bang here!
The logic flows, and tests retreat. ✨

Description Check	✅ Passed	Check skipped - CodeRabbit’s high-level summary is enabled.
Title Check	✅ Passed	The title "Fix/element not found develop：Add condition for when element is null" is clearly related to the primary change in this changeset. The main modification in packages/canvas/container/src/container.ts adds a condition to return a default delay of 50 ms when an element cannot be resolved (element is null), which directly aligns with the title's stated purpose. The two secondary changes to the filter predicates in the Vue files are minor stylistic refactorings that don't need to be captured in the title. A teammate reviewing the commit history would understand that this PR addresses missing element handling with a default timeout.
