    travis build code coverage npm package

    Voca is a JavaScript library for manipulating strings. https://vocajs.com

    v.camelCase('bird flight');              // => 'birdFlight'
    v.sprintf('%s costs $%.2f', 'Tea', 1.5); // => 'Tea costs $1.50'
    v.slugify('What a wonderful world');     // => 'what-a-wonderful-world'

    The Voca library offers helpful functions to make string manipulations comfortable: change case, trim, pad, slugify, latinise, sprintf'y, truncate, escape and much more. The modular design allows to load the entire library, or individual functions to minimize the application builds. The library is fully tested, well documented and long-term supported.


    • Provides the complete set of functions to manipulate, chop, format, escape and query strings
    • Includes detailed, easy to read and searchable documentation
    • Supports a wide range of environments: Node.js 0.10+, Chrome, Firefox, Safari 7+, Edge 13+, IE 9+
    • 100% code coverage
    • No dependencies


    See the complete documentation at https://vocajs.com


    Voca can be used in various environments.

    Node.js, Rollup, Webpack, Browserify

    Voca JavaScript library supports Node.js, Rollup, Webpack, Browserify

    Install the library with npm into your local modules directory:

    npm install voca

    CommonJS modules

    Then in your application require the entire library:

    var v = require('voca');
    v.trim(' Hello World! ');            // => 'Hello World'
    v.sprintf('%d red %s', 3, 'apples'); // => '3 red apples'

    Or require individual functions:

    var words = require('voca/words');
    var slugify = require('voca/slugify');
    words('welcome to Earth'); // => ['welcome', 'to', 'Earth']
    slugify('caffé latté');    // => 'caffe-latte'

    ES2015 modules

    Voca is compatible with ES2015 modules to import the entire library:

    import voca from 'voca';
    voca.kebabCase('goodbye blue sky'); // => 'goodbye-blue-sky'

    Or import individual functions:

    import last from 'voca/last';
    last('sun rises', 5); // => 'rises'


    Voca JavaScript library supports Chrome, Firefox, Safari, Edge, Internet Explorer

    Load the UMD builds directly into browser's web page:

    <script src="voca.js" type="text/javascript"></script>

    Then a global variable v is exposed for the entire library:

    <script type="text/javascript">
      v.last('wonderful world', 5); // => 'world'

    v.insert v.endsWith v.charAt v.camelCase v.indexOf
    v.latinise v.includes v.codePointAt v.capitalize v.lastIndexOf
    v.pad v.isAlpha v.first v.decapitalize v.search

    v.replace v.isEmpty v.slice v.swapCase v.unescapeHtml
    v.replaceAll v.isLowerCase v.substr v.titleCase Strip
    v.reverse v.isNumeric v.substring v.upperCase v.stripBom
    v.reverseGrapheme v.isString v.truncate Split v.stripTags
    v.slugify v.isUpperCase Count v.chars
    v.splice v.matches v.count v.codePoints
    v.tr v.startsWith v.countGraphemes v.graphemes
    v.trim Format v.countSubstrings v.split
    v.trimLeft v.sprintf v.countWhere v.words
    v.trimRight v.vprintf v.countWords
