More examples

import { iWantRegex } from 'nebur-regex';

// Creating a set of regex constraints using 'iWantRegex', chaining various rules.
const constraints = 
  iWantRegex() // Initializing the regex constraint builder
  .toBeAlphanumeric() // Enforcing alphanumeric characters only
  .toBeCreditCardNumber() // Ensuring a valid credit card number format
  .toBeDate() // Checking if the input is a valid date => Format: MM/DD/YYYY | M/D/YYYY | MM-DD-YYYY | M-D-YYYY
  .toBeEmail() // Validating the input as an email address
  .toBeHexColor() // Confirming the input is a valid hex color code
  .toBeLowercase() // Verifying that all characters are in lowercase
  .toBeNumeric() // Ensuring the input consists of numeric characters only
  .toBePhoneNumber() // Validating the input as a phone number
  .toBeURL() // Checking if the input is a valid URL
  .toBeUppercase() // Verifying that all characters are in uppercase
  .toContains('hi') // Checking if the input contains the substring 'hi'
  .toMatch(/^([0-9]+)$/) // Ensuring the input matches the specified regex pattern (only digits)
  .end(); // Always End the chaining of regex constraints

// Testing the constraints against the string "hello world"
const isValid = constraints.test("hello world"); 

// Logging the result of the validation
console.log('isValid', isValid); // false;
