The @type-ddd/email module provides a class Email for handling email addresses in TypeScript. It includes methods for validating email addresses, extracting parts of the email (such as nickname and domain), and creating instances of validated emails.
Install rich-domain and @type-ddd/email with your favorite package manager:
npm i rich-domain types-ddd/email
#OR
yarn add rich-domain types-ddd/email
import { Email } from '@type-ddd/email';
// Check if is valid value
const isValid = Email.isValid('sample@domain.com');
// true
// Initialize Email instance with a valid email address
const email = Email.init('example@example.com');
// OR
// Create Email instance from provided email address
const result = Email.create('example@example.com');
// Get parts of the email address
const nickname = email.nick();
const domain = email.domain();
If you want to block some specifics domains
import { Email } from '@type-ddd/email';
const list = ['hack.com'];
Reflect.set(Email, 'BLOCKED_DOMAINS', list);
const isValid = Email.isValid('user@hack.com');
// false
const isValid = Email.isValid('user@gmail.com');
// trueIf you want to allow only some specifics domains
import { Email } from '@type-ddd/email';
const list = ['my-company.com'];
Reflect.set(Email, 'VALID_DOMAINS', list);
const isValid = Email.isValid('user@my-company.com');
// true
const isValid = Email.isValid('user@gmail.com');
// false
