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.

$3

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

if (EmailSyntax.validate('test@some-mail.com')){
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

$3

`typescript
import { EmailSyntax } from 'email-syntax';

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

``
