Importing

node

let types = require('ee-types');

require.js

you have to configure require.js to point the bower prefix to the bower_components folder.

requirejs.config({
    paths: {
        'bower': '/js/bower_components/'
    }
});

and finally load the component

require(['bower/ee-types/dist/ee-types.min'], function(types) {
    
});

Browser & Vanilla

<script src="bower/ee-types/dist/ee-types.min" />

var types = window.ee.types;

API

Explicity test for a type

types.array([]) // true

Get the type of some input

types(/[a-z]+/gi) // regexp

Object Types

Since many of the types defined by javascript are just special objects that also can be treated as normal objects ee-types has are a bunch of methods that allow you to handle that correctly.

For example Map is an object too. Or custom class where you define a getter that returns a specific name for your object:

const X = class {
    get [Symbol.toStringTag]() {
        return 'AQL query';;
    }
};

console.log(Object.prototype.toString.call(new X()));
// prints: [object AQL Query]

Check for a classic object

types.object({}); // true
types.object(new Map()); // false

// be aware that if you are not explicitly testing
// for an object any obecjt will be treated as one
types({}) // 'object'
types(new Map()) // 'object'

Check any type of object

types.someObject({}); // true
types.someObject(new Map()); // false
types(new Map()) // 'object'

Examples

var types = require('ee-types');


types.string('nope');                // true
types.strign(new String('yeah'));    // true


types(2) // number

types([]]) // array
types(new Array()]) // array
types(new Int8Array()]) // int8Array


types.promise(Promise.all()) // true
