Line range hint
110-117: Consider using a signal for the cancel button visibility.While the changes align with moving logic to the component, using a method call
hasCancelButton()in the template could lead to unnecessary re-evaluations during change detection cycles. Consider using a signal or computed property instead.Example refactor:
- @if (hasCancelButton()) { + @if (showCancelButton()) {In the component:
showCancelButton = computed(() => { // your cancel button logic here });src/test/javascript/spec/component/lecture-unit/video-unit/video-unit-form.component.spec.ts (3)
Line range hint
41-163: Consider refactoring repeated spy setup patterns.The tests repeat the same spy setup pattern across multiple test cases:
jest.spyOn(videoUnitFormComponent, 'videoSourceUrlValidator').mockReturnValue(undefined); jest.spyOn(videoUnitFormComponent, 'videoSourceTransformUrlValidator').mockReturnValue(undefined);Consider extracting this into a helper method to improve maintainability:
function setupVideoValidatorSpies(component: VideoUnitFormComponent): void { jest.spyOn(component, 'videoSourceUrlValidator').mockReturnValue(undefined); jest.spyOn(component, 'videoSourceTransformUrlValidator').mockReturnValue(undefined); }
Line range hint
119-163: Consider grouping URL transformation tests.The URL transformation tests for YouTube and TUM-Live could be grouped under a describe block for better organization:
describe('URL transformations', () => { it('should correctly transform YouTube URL into embeddable format', () => { // existing test }); it('should correctly transform TUM-Live URL without video only into embeddable format', () => { // existing test }); });
Line range hint
165-175: Input handling changes look good, consider additional test cases.The migration to using
setInputfor component inputs is correct and aligns with the signal-based approach. However, consider adding test cases for:
- Input change detection (when formData changes after initial setup)
- Edge cases with null/undefined input values
Example additional test:
it('should update form when formData input changes', () => { videoUnitFormComponentFixture.componentRef.setInput('isEditMode', true); const initialData: VideoUnitFormData = { name: 'initial', description: 'initial desc', releaseDate: dayjs(), source: 'initial-source' }; videoUnitFormComponentFixture.componentRef.setInput('formData', initialData); videoUnitFormComponentFixture.detectChanges(); const updatedData: VideoUnitFormData = { name: 'updated', description: 'updated desc', releaseDate: dayjs(), source: 'updated-source' }; videoUnitFormComponentFixture.componentRef.setInput('formData', updatedData); videoUnitFormComponentFixture.detectChanges(); expect(videoUnitFormComponent.nameControl?.value).toEqual(updatedData.name); expect(videoUnitFormComponent.descriptionControl?.value).toEqual(updatedData.description); });src/main/webapp/app/lecture/lecture-unit/lecture-unit-management/video-unit-form/video-unit-form.component.ts (3)
90-95: Consider cleaning up theeffectto prevent potential memory leaksWhile Angular automatically handles the cleanup of effects within components, explicitly unsubscribing can prevent potential memory leaks and align with the coding guideline
memory_leak_prevention:true.You can store the effect cleanup function and call it in
ngOnDestroy:+ private readonly formEffectCleanup = effect(() => { if (this.isEditMode() && this.formData()) { untracked(() => this.setFormValues(this.formData()!)); } - }); + }); + ngOnDestroy() { + this.formEffectCleanup(); + }
78-85: Simplify form control initialization by removing unnecessary type assertionsThe type assertions using
as Type | undefinedare unnecessary since TypeScript can infer the types from the default values. This simplification enhances readability.Update the form controls as follows:
- name: [undefined as string | undefined, [Validators.required, Validators.maxLength(255)]], + name: ['', [Validators.required, Validators.maxLength(255)]], - description: [undefined as string | undefined, [Validators.maxLength(1000)]], + description: ['', [Validators.maxLength(1000)]], - releaseDate: [undefined as dayjs.Dayjs | undefined], + releaseDate: [null as dayjs.Dayjs | null], - source: [undefined as string | undefined, [Validators.required, this.videoSourceUrlValidator]], + source: ['', [Validators.required, this.videoSourceUrlValidator]], - urlHelper: [undefined as string | undefined, this.videoSourceTransformUrlValidator], + urlHelper: ['', this.videoSourceTransformUrlValidator], - competencyLinks: [undefined as CompetencyLectureUnitLink[] | undefined], + competencyLinks: [[], []],
87-87: Ensure method calls in templates adhere to performance best practicesCalling methods like
isFormValid()in the template is acceptable when using signals. However, per the coding guidelinemethods_in_html:false, it's important to ensure these methods are efficient and do not negatively impact performance.Consider storing
isFormValidas a property if it doesn't need to recompute frequently or ensure that the computed signal is optimized.- isFormValid = computed(() => this.statusChanges() === 'VALID'); + readonly isFormValid = computed(() => this.statusChanges() === 'VALID');Ensure that in the template, you're calling
isFormValid()and that it doesn't trigger unnecessary re-evaluations.

Line range hint 3-3: LGTM! Proper usage of new Angular control flow syntax.
The template correctly uses the new @if syntax throughout, replacing the older *ngIf directives. The form validation structure is well-organized and follows Angular best practices.
Also applies to: 8-8, 14-14, 15-15, 16-16, 17-17, 18-18, 19-19, 20-20, 21-21, 22-22, 23-23, 24-24, 25-25, 26-26, 27-27, 28-28, 29-29, 30-30, 31-31, 32-32, 33-33, 34-34, 35-35, 36-36, 37-37, 38-38, 39-39, 40-40, 41-41, 42-42, 43-43, 44-44, 45-45, 46-46, 47-47, 48-48, 49-49, 50-50, 51-51, 52-52, 53-53, 54-54, 55-55, 56-56, 57-57, 58-58, 59-59, 60-60, 61-61, 62-62, 63-63, 64-64, 65-65, 66-66, 67-67, 68-68, 69-69, 70-70, 71-71, 72-72, 73-73, 74-74, 75-75, 76-76, 77-77, 78-78, 79-79, 80-80, 81-81, 82-82, 83-83, 84-84, 85-85, 86-86, 87-87, 88-88, 89-89, 90-90, 91-91, 92-92, 93-93, 94-94, 95-95, 96-96, 97-97, 98-98, 99-99, 100-100, 101-101, 102-102, 103-103, 104-104, 105-105, 106-106, 107-107, 108-108, 109-109

Line range hint 1-39: Test setup follows best practices!
The configuration demonstrates good practices:
- Proper use of NgMocks for mocking components and pipes
- Focused imports without unnecessary dependencies
- Clean TestBed configuration without schemas

65-65: Usage of inject() aligns with Angular best practices
The use of inject(FormBuilder) is appropriate and leverages Angular's dependency injection in a functional way. This aligns with modern Angular patterns.
86-87: Conversion of statusChanges to a signal is correct
Transforming form.statusChanges into a signal using toSignal is a valid approach for reactive form handling with signals. This ensures that isFormValid updates automatically based on form validity.
92-92: Confirm the necessity of untracked within the effect
Using untracked prevents the setFormValues method from creating additional dependencies that could retrigger the effect unnecessarily. Ensure this is intentional and does not skip updates that should be tracked.
Please verify that untracked is necessary here and doesn't omit any required reactive updates.
72-73: Usage of input and output signals is appropriate
Defining hasCancelButton and onCancel using input and output functions modernizes the component and leverages Angular's signal APIs effectively.

@anditurdiu #9692 (review) Which failing client test are you referring to? https://bamboo.ase.in.tum.de/browse/ARTEMIS-TESTS7337-TSTEST-1 The GitHub Action tasks are flaky, as far as I know that's why they did not replace the Bamboo pipelines yet. |

Motivation and Context
This PR introduces signals, and fixes code smells in components used for editing and updating lectures. This is a preparation for Lectures: Add status bar to lecture creation and edit mode #9655 and aims to keep #9655 at a manageable size of changes.
Description
video-unit-form.component.ts(and thereby removed method calls in the template)Steps for Testing
Prerequisites:
Lectures: Add status bar to lecture creation and edit mode #9655)Units>Videoto create a text lecture unit, verify the behavior is the same as on developThis is a refactoring PR that does not add functionality, so the behavior should not change in comparison to the develop branch.
