next-is.js

is.js is a micro javascript library that helps you with conditions. This fork of is.js is not poluting global scope. It's able to work on both: NodeJS and Browser.

This library may be simple replacement for any validation library, modernizr etc.

Installation

npm install --save next-is

browser: <script src="is.js"></script>

is.js is available under window.is

node/require/amd (webpack): npm install --save next-is

const is = require('next-is');

After that you have already finished with the installation. Inside your main script you can already start using next-is.js!

Examples:

// Object functions:
var str = 'my string';
is.isString(str); // return true
is.isEmpty(str); // return false
is.isArray(str); // return false

is.string.isBlank(str);   // return false
is.string.isBlank('');    // return true
is.string.isBlank('   '); // return true

is.string.isEmail('[email protected]'); // return true
is.string.isCC('5156300575820365');  // return true
is.string.isCC( '5156300575820365', 'Visa' ) // return false

// also is.js have some core functions:
is.windows();
is.chrome();
is.mobile();
is.online();

if(is.isString(str)){
  // do stuffs here
}
if(is.desktop()){
  // do stuffs here
}
