Package Exports

dynamic-class-list

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (dynamic-class-list) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

dynamic-class-list

Simple, fast module for getting strings of dynamic and conditional class list.

Features:

Support string arguments.
Support number arguments.
Support object arguments.
Support array arguments.
Support functions.
Ignore bad values like null and undefined.
Zero-dependency.

Quickstart - CommonJS

npm install dynamic-class-list

Or using yarn

yarn add dynamic-class-list

Then require it in your module ...

var getClassNames = require('dynamic-class-list').getClassNames; // deprecated
var classList = require('dynamic-class-list').classList;

OR using ES6 imports

import { getClassNames, classList } from 'dynamic-class-list';

Note that getClassNames is deprecated and will be removed in next major release. You should use classList moving forward.

API

Arguments as strings

// As Arguments
getClassNames('class1', 'class2');
// OR
classList('class1', 'class2');

// Output : "class1 class2"

Arguments as an array of strings

// As an Array
classList(['class1', 'class2']);

// Output : "class1 class2"

classList([null, undefined, 3, 'class1', 'class2']);

// Output : "3 class1 class2"

Arguments as an object

Note that the key is used as the class if its value is truthy

// As an Object
classList({class1: true, class2 : false});

// Output : "class1"

classList({class1: undefined, class2 : null, class3: true, class4: false});

// Output : "class3"

Note that the function should return a boolean

// Value as a function As an Object
classList({ 
    class1: function() { return false; },
    class2 : function() { return true; }
});

// Output : "class2"

Hybrid Arguments

// using all type of data
classList('class1', 'class2', 2, null, undefined, ['class3', null, undefined, 4, 'class4'], { 
    class5 : function() { return false; },
    class6 : function() { return true; },
    class7: undefined,
    class8: true,
    class9: false
});

// Output : "class1 class2 2 class3 4 class4 class6 class8"
