Unused Standalone Imports

This diagnostic detects cases where the imports array of a @Component contains symbols that aren't used within the template.

typescript

@Component({
  imports: [UsedDirective, UnusedPipe],
})
class AwesomeCheckbox {}

What's wrong with that?

The unused imports add unnecessary noise to your code and can increase your compilation time.

Delete the unused import.

typescript

@Component({
  imports: [UsedDirective],
})
class AwesomeCheckbox {}

This diagnostic can be disabled by editing the project's tsconfig.json file:

      "checks": {
        "unusedStandaloneImports": "suppress"
      }
    }
  }
