commons-validator-es

Apache Commons Validator ported to TypeScript as a tree-shakable ES6 module

Usage

Install the library with npm install commons-validator-es

To use as an ES6 module:

import { isEmail } from 'commons-validator-es';

isEmail('test@test.com'); // => true
isEmail('test@test.con'); // => false!

It works as a CommonJS module too, for backwards compatibility

const validator = require('commons-validator-es');

validator.isEmail('test@test.com'); // => true
validator.isEmail('test@test.con'); // => false!

Supported validators

Validator	Description
isEmail(email, allowLocal?, allowTld?)	Checks if email is a valid email address. Ensures fields like the TLD are valid (no .con!) If allowLocal is true, emails like test@localhost are valid If allowTld is true, emails like test@com are valid
isDomain(domain, allowLocal?)	Checks if domain is a valid domain name If allowLocal is true, domains like localhost.localdomain are valid, as are single name labels (like hostname)
isTld(tld, allowLocal?)	Checks if tld is a valid tld (.com is allowed but .con is not, for example) If allowLocal is true, tlds like localdomain are valid
isIpAddress(address)	Checks if address is a valid IPv4 or IPv6 address
isIpv4Address(address)	Checks if address is a valid IPv4 address
isIpv6Address(address)	Checks if address is a valid IPv6 address
isCountryCodeTld(ccTld)	Checks if ccTld is a valid country code TLD (like .au)
isGenericTld(gTld)	Checks if gTld is a valid generic TLD (like .com)
isInfrastructureTld(iTld)	Checks if iTld is a valid infrastructure TLD (only valid is .arpa)
isLocalTld(lTld)	Checks if lTld is a valid local TLD (like .localdomain)

Inspiration

commons-validator-js hasn't been updated in a while and does not export an ES6 module. I'll be continuing to add more validators to this to bring it to parity with Apache Commons Validator
