$ npm install nebur-regeximport { iWantRegex } from 'nebur-regex'; // ES6 module
//OR
const { iWantRegex } = require('nebur-regex'); // CommonJs
const constraints =
iWantRegex()
.toContains('@')
.toBeEmail()
.end();
const isValid = constraints.test("test@test.com");
console.log(isValid); //trueimport { 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;- Author - Ruben Merson Nzaou
