@stdlib/assert-is-email-address NPM

isEmail

Test if a value is an email address.

Installation

npm install @stdlib/assert-is-email-address

Usage

var isEmail = require( '@stdlib/assert-is-email-address' );

isEmail( value )

Tests if a value is an email address.

var bool = isEmail( 'beep@boop.com' );
// returns true

Notes

Validation is not rigorous, nor should it be. 9 RFCs relate to email addresses, and accounting for all of them is a fool's errand. This module performs the simplest validation; i.e., requiring at least one @ symbol.
For rigorous validation, send a confirmation email. If the email bounces, consider the email invalid.

Examples

var isEmail = require( '@stdlib/assert-is-email-address' );

var bool;

bool = isEmail( 'beep@boop.com' );
// returns true

bool = isEmail( 'beep' );
// returns false

bool = isEmail( 'beep.com' );
// returns false

bool = isEmail( null );
// returns false

Notice

This package is part of stdlib, a standard library for JavaScript and Node.js, with an emphasis on numerical and scientific computing. The library provides a collection of robust, high performance libraries for mathematics, statistics, streams, utilities, and more.
