Issue: Automating Component Dependency Imports in Angular
Labels: area: core,cross-cutting: standalone

### Which @angular/* package(s) are relevant/related to the feature request?

_No response_

### Description

Automating the import of necessary component dependencies would significantly enhance developer productivity and reduce repetitive code.

Currently, developers are required to manually create an array of essential dependencies that need to be imported for a component to function properly. This process can be tedious and error-prone, as it requires developers to remember which dependencies are necessary and add them to the imports array themselves.

### Proposed solution

Is it possible for Angular to automate this process by generating the imports array based on the component class (using ES6 imports) and the associated template?

For instance, consider the following component:

```
import { CommonModule } from '@angular/common';
import { Component, inject, signal, ChangeDetectionStrategy, viewChild } from '@angular/core';
import { FormControl, ReactiveFormsModule } from '@angular/forms';
import { MatButtonModule } from '@angular/material/button';
import { MatChipsModule } from '@angular/material/chips';
import { MatDialog } from '@angular/material/dialog';
import { MatFormFieldModule } from '@angular/material/form-field';
import { MatIconModule } from '@angular/material/icon';
import { MatInputModule } from '@angular/material/input';
import { MatMenuModule } from '@angular/material/menu';
import { MatPaginator, MatPaginatorModule } from '@angular/material/paginator';
import { MatProgressSpinnerModule } from '@angular/material/progress-spinner';
import { MatSnackBar } from '@angular/material/snack-bar';
import { MatTableDataSource, MatTableModule } from '@angular/material/table';
import { MatToolbarModule } from '@angular/material/toolbar';
import { MatTooltipModule } from '@angular/material/tooltip';
import { Params, RouterModule } from '@angular/router';

@Component({
  selector: 'app-user-list',
  imports: [
    CommonModule,
    MatTableModule,
    MatPaginatorModule,
    MatFormFieldModule,
    MatInputModule,
    MatToolbarModule,
    MatProgressSpinnerModule,
    MatButtonModule,
    MatIconModule,
    RouterModule,
    MatTooltipModule,
    MatChipsModule,
    MatMenuModule,
    ReactiveFormsModule,
  ],
  changeDetection: ChangeDetectionStrategy.OnPush,
  templateUrl: './user-list.component.html',
  styleUrls: ['./user-list.component.scss'],
})
export class UserListComponent {}
```

This component could be defined without manually listing the imports array, reducing redundancy:

```
import { CommonModule } from '@angular/common';
import { Component, inject, signal, ChangeDetectionStrategy, viewChild } from '@angular/core';
import { FormControl, ReactiveFormsModule } from '@angular/forms';
import { MatButtonModule } from '@angular/material/button';
import { MatChipsModule } from '@angular/material/chips';
import { MatDialog } from '@angular/material/dialog';
import { MatFormFieldModule } from '@angular/material/form-field';
import { MatIconModule } from '@angular/material/icon';
import { MatInputModule } from '@angular/material/input';
import { MatMenuModule } from '@angular/material/menu';
import { MatPaginator, MatPaginatorModule } from '@angular/material/paginator';
import { MatProgressSpinnerModule } from '@angular/material/progress-spinner';
import { MatSnackBar } from '@angular/material/snack-bar';
import { MatTableDataSource, MatTableModule } from '@angular/material/table';
import { MatToolbarModule } from '@angular/material/toolbar';
import { MatTooltipModule } from '@angular/material/tooltip';
import { Params, RouterModule } from '@angular/router';

@Component({
  selector: 'app-user-list',
  changeDetection: ChangeDetectionStrategy.OnPush,
  templateUrl: './user-list.component.html',
  styleUrls: ['./user-list.component.scss'],
})
export class UserListComponent {}

```

Currently, a significant amount of code is duplicated, and developers must remember to add the necessary dependencies to the imports array manually. Automating this process would streamline development, minimize errors, and allow developers to focus on building features rather than managing boilerplate code.

### Alternatives considered

- Provide an `Angular CLI` command that scans component files and generates the required imports automatically.
- Create an IDE or editor extension that assists developers in identifying and adding required imports as they code.
