import { FormControl } from '@angular/forms';
import { NguardValidators } from 'ng-nguard';

const rating = new FormControl('', [NguardValidators.Number.between(1, 5)]);

Template-driven forms​

<input ngModel name="rating" [nguardBetween]="[1, 5]" />

The directive accepts a [number, number] tuple.

{ between: true }

Notes​

  • The check is inclusive on both ends — between(1, 5) accepts 1 and 5.
  • Numeric strings work — '3' passes between(1, 5).
  • null, undefined, empty string, NaN, Infinity all fail.
  • Throws RangeValidatorErrors.MinGreaterThanMax if minVal > maxVal.
