minLength

Validate that a string has at least N characters.

NguardValidators.String.minLength(n: number): ValidatorFn
ParameterTypeDescription
nnumberMinimum required length

Reactive forms​

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

const password = new FormControl('', [NguardValidators.String.minLength(8)]);

Template-driven forms​

<input ngModel name="password" type="password" [nguardMinLength]="8" />

{ minLength: true }

Notes​

  • The check is >= (inclusive). minLength(8) accepts length 8.
  • null, undefined, non-string inputs all fail.
  • Whitespace counts toward length — pair with notBlank if needed.
