email-syntax

Email addresses syntax validations library

Syntax email addresses verification based on RFC5321 and RFC5322. Version 2 is full remake of original one using TypeScript. Now it's a class with one static method "validate". Library can be used in Node.js back-end and in Angular 4 front-end projects.

Installation

Install Email Syntax as an npm module and save it to your package.json file as a dependency:

npm install --save email-syntax

Usage

Usage of validator is simple as 2 + 2. You need to import class and then use its "validate()" method.

Node.js

    const EmailSyntax = require('email-syntax').EmailSyntax;

    if (EmailSyntax.validate('[email protected]')){
        console.log('This address is valid');
    }

On server environment you can use additional methods:

• split(address) - Splits email address to local part and domain name
• extractFromQuotes(localPart) - Checks if quoted and extracts local part
• validateDomainName(domainName) - Validates domain name syntaxis
• validateLocalPart(localPart) - Validates local-part of address
• isValidIpAddress(domainName) - Checks if domain name is a valid ip address like 1.2.3.4

Angular 2/4

    import { EmailSyntax } from 'email-syntax';

    function isEmailValid(address): boolean{
        return EmailSyntax.validate(address);
    }
