API Documentation for GVDefaultValidators

Description

GVDefaultValidators is a utility class that provides a set of static methods to create custom validators used in conjunction with the @GV decorator for model validation. Each static method returns a ValidatorFn, which is a function that validates form control values based on specific rules. These validators can be applied to properties of a model class to enforce various validation constraints, such as required fields, specific patterns, minimum and maximum lengths, numeric values, email format, and more.

Static Methods

required(): ValidatorFn

Description: Creates a validator function that checks whether a form control has a non-null and non-undefined value, ensuring that the control is required.

Usage:

import { GV } from '@releasium/ngx-grand-validator';

class UserModel {
  @GV.required()
  firstName: string;
}

pattern(pattern: RegExp): ValidatorFn

Description: Creates a validator function that checks whether a form control value matches the provided regular expression pattern.

Parameters:

• pattern (RegExp): The regular expression pattern to be matched.

Usage:

import { GV } from '@releasium/ngx-grand-validator';

class UserModel {
  @GV.pattern(/^[A-Za-z]+$/)
  username: string;
}

digit(): ValidatorFn
