Communication: Improve sidebar user interface design

[asliayk]

Checklist

General

• I tested all changes and their related features with all corresponding user types on a test server.
• Language: I followed the guidelines for inclusive, diversity-sensitive, and appreciative language.
• I chose a title conforming to the naming conventions for pull requests.

Client

• I strictly followed the client coding and design guidelines.
• Following the theming guidelines, I specified colors only in the theming variable files and checked that the changes look consistent in both the light and the dark theme.
• I added multiple integration tests (Jest) related to the features (with a high test coverage), while following the test guidelines.
• I added multiple screenshots/screencasts of my UI changes.
• I translated all newly inserted strings into English and German.

Motivation and Context

1st issue: Next to each channel section header in sidebar, there was a "+" icon for channel creation. Even in sections where users couldn’t create a channel (e.g., the "exam" section), the "+" button was still visible. This was unnecessary and added clutter. And when this was clicked, the user first had to view the browse channel screen and then click the button in that dialog again to create a channel. Having too many icons and the need to open two dialogs one after the other was not user-friendly.

2nd issue: As discussed in the communication subgroup, the section header should not be visible when there are no channels/conversations in that section.

3rd issue: Although the prefixes "exercise-", "lecture-", and "exam-" were included in the names of the exercise, lecture, and exam channels respectively, their presence was unnecessary since the channels were already grouped into their corresponding sections. This made the interface look complicated.

Description

1st issue:

• Immediately above the sidebar, there is now a single button that, when clicked, opens a dropdown menu containing four options: "Create Direct Chat," "Create Group Chat," "Create Channel" and "Browse Channels."
• The plus button next to each section header for adding channels are removed.

2nd issue: If a section is empty (i.e., there are no channels or conversations), the section header is no longer visible.

3rd issue: The channel prefixes ("exercise-" "lecture-" and "exam-") do not appear in their respective sections; they are only visible in the favorite and hidden sections.

Steps for Testing

Prerequisites:

• 1 Instructor

1. Log in to Artemis
2. Navigate to Communication section of a course
3. Notice that there is a new button above the sidebar. By clicking on this button and selecting respective options, create direct chat, group chat and new channel. Then click on browse channels to open the browse channels dialog.
4. Notice that in exercise, exam and lecture sections, the channels have no prefixes ("exercise-" "lecture-" and "exam-"), but they become visible if you hide/favorite them and they are in hidden/favorites section.
5. If there is no hidden channel, the hidden section should not be visible. If there exist hidden channels, make them visible by clicking on their 3-dot button to see the options and click on "Show". When there is no hidden channel anymore, notice that hidden section is not visible.

src/main/webapp/app/shared/sidebar/sidebar-card-small/sidebar-card-small.component.ts (1)

Line range hint 1-46: Suggestions for improving component structure and navigation logic

While the overall structure of the component is good, here are some suggestions for improvement:

1. The refreshChildComponent method uses complex navigation logic. Consider simplifying this or adding comments to explain the purpose of each step.

2. The use of skipLocationChange followed by immediate navigation might be inefficient. Can this be optimized?

3. Add error handling for the navigation promises to improve robustness:

this.router.navigate(['../'], { skipLocationChange: true, relativeTo: this.route.firstChild })
    .then(() => {
        // ... existing code ...
    })
    .catch(error => {
        console.error('Navigation failed:', error);
        // Handle the error appropriately
    });

4. Consider implementing lifecycle hooks like ngOnInit or ngOnDestroy if there's any initialization or cleanup logic needed.

5. The emitStoreAndRefresh method name doesn't clearly indicate its full functionality. Consider renaming it to something more descriptive, like emitEventAndRefreshView.

src/main/webapp/app/shared/sidebar/sidebar.module.ts (1)

Line range hint 1-39: Enhance readability of imports and declarations.

The overall structure of the module looks good and aligns with Angular best practices. To further improve readability and maintainability, consider applying the same multi-line format to the imports and declarations arrays.

Here's an example of how you could format the imports and declarations:

import { NgModule } from '@angular/core';
import {
    ArtemisSharedModule,
    ArtemisSidePanelModule,
    ArtemisSharedPipesModule,
    ArtemisExerciseButtonsModule,
    ArtemisCourseExerciseRowModule,
    ArtemisSharedCommonModule,
    SubmissionResultStatusModule,
    ArtemisExamSharedModule,
} from 'app/shared/...'; // Adjust the import paths as needed

import {
    SidebarAccordionComponent,
    SidebarCardSmallComponent,
    SidebarCardMediumComponent,
    SidebarCardLargeComponent,
    SidebarCardItemComponent,
    SidebarComponent,
    ConversationOptionsComponent,
} from './...'; // Adjust the import paths as needed

@NgModule({
    imports: [
        ArtemisExerciseButtonsModule,
        ArtemisCourseExerciseRowModule,
        ArtemisSharedModule,
        ArtemisSharedPipesModule,
        ArtemisSidePanelModule,
        ArtemisSharedCommonModule,
        SubmissionResultStatusModule,
        SidebarCardDirective,
        ArtemisExamSharedModule,
    ],
    declarations: [
        SidebarAccordionComponent,
        SidebarCardSmallComponent,
        SidebarCardMediumComponent,
        SidebarCardLargeComponent,
        SidebarCardItemComponent,
        SidebarComponent,
        ConversationOptionsComponent,
    ],
    // ... exports (as suggested in the previous comment)
})
export class ArtemisSidebarModule {}

This format improves readability and makes it easier to add or remove items in the future.

src/main/webapp/app/shared/sidebar/sidebar-accordion/sidebar-accordion.component.ts (2)

Line range hint 12-30: LGTM: Class properties updated to support new sidebar design

The changes to the class properties align well with the PR objectives:

1. Removal of showAddOptions and showAddOption simplifies the component's interface.
2. Addition of channelTypeIcon supports the new channel prefix display logic.
3. New isFilterActive property likely supports the updated filtering behavior.

The property naming follows the camelCase convention as per coding guidelines, and @Input() decorators are used correctly.

Consider adding a type annotation to the isFilterActive property for consistency:

@Input() isFilterActive: boolean = false;

---

Line range hint 32-72: LGTM: Methods updated to support new sidebar functionality

The changes to the methods align with the PR objectives:

1. Removal of getGroupKey simplifies the component's logic.
2. expandAll method now considers the isFilterActive property, supporting the new filtering behavior.

The methods follow camelCase naming convention and use arrow function syntax as per coding guidelines. There are no apparent memory leaks.

For consistency with the coding guidelines, consider using single quotes for strings in the setStoredCollapseState and toggleGroupCategoryCollapse methods. For example:

sessionStorage.setItem('sidebar.accordion.collapseState.' + this.storageId + '.byCourse.' + this.courseId, JSON.stringify(this.collapseState));

src/main/webapp/app/overview/course-conversations/course-conversations.component.html (1)

Line range hint 1-72: Consider using consistent Angular syntax throughout the file

The file currently uses a mix of *ngIf and the new @if syntax for conditional rendering. For consistency and to align with modern Angular practices, consider updating all instances to use the new @if syntax. This includes lines like:

<div class="input-group mb-2 rounded-3 p-2 me-2 module-bg" [hidden]="!isCodeOfConductAccepted">

which could be changed to:

@if (isCodeOfConductAccepted) {
    <div class="input-group mb-2 rounded-3 p-2 me-2 module-bg">
        <!-- content -->
    </div>
}

Similarly, update other *ngIf instances throughout the file.

src/main/webapp/app/overview/course-conversations/dialogs/channels-overview-dialog/channels-overview-dialog.component.ts (1)

Old Channel Creation Dialog Still Present

The method openCreateChannelDialog is still found in course-conversations.component.ts, indicating that the old channel creation dialog was not fully removed. Additionally, new channel creation methods like createChannel and addChannel are present, but the presence of the old method suggests incomplete refactoring.

• src/main/webapp/app/overview/course-conversations/course-conversations.component.ts: openCreateChannelDialog

Analysis chain

Line range hint 27-127: LGTM! Verify new channel creation process.

The removal of otherChannels, openCreateChannelDialog, and the NgbModal service from the constructor aligns with the PR objectives of simplifying the channel creation process and streamlining the UI. These changes suggest that the channel creation process is now handled differently, possibly through the new "Create Chat" and "Add Channel" buttons mentioned in the PR objectives.

To ensure that the new channel creation process is properly implemented, please run the following verification script:

This script will help verify that the new channel creation process has been properly implemented across the relevant files in the project.

src/test/javascript/spec/component/shared/sidebar/sidebar-accordion.component.spec.ts (1)

Line range hint 1-148: Overall, the test suite is comprehensive and well-structured.

The test cases cover various aspects of the SidebarAccordionComponent's functionality, including toggling collapse states, handling search and filter changes, and expanding groups. The use of mocking and assertions is consistent with best practices and the provided coding guidelines.

However, considering the PR objectives mentioned in the summary, there might be an opportunity to enhance the test coverage:

1. Add tests for the new "Create Chat" and "Add Channel" buttons and their dropdown menus.
2. Verify that section headers are not visible when there are no channels or conversations in that section.
3. Check that the prefixes "exercise-", "lecture-", and "exam-" are correctly handled in the main view and in the favorites and hidden sections.

These additions would ensure that the new features and changes are properly tested.
