    ampersand-class-extend

    Helper function for setting up prototype chains for subclasses.

    Largely copied out of Backbone, but modified to enable extending a prototype with multiple mixins at once.

    install

    npm install ampersand-class-extend
    

    usage

    Your base object module might look something like this:

    var extend = require('ampersand-class-extend');
     
     
    // your base object
    function YourConstructor() {}
     
    // simply attach it directly to the object constructor
    YourConstructor.extend = extend;
     
    // export it
    module.exports = YourConstructor;
     

    Then in a file using said constructor:

    var YourConstructor = require('./your-constructor');
    var mixinMethods = require('some-other-methods');
    var otherMixinMethods = require('even-more-methods');
     
     
    // Nowe we add some more stuff and export a modified constructor 
    // (we can pass in as many other objects containing methods as we want).
    module.exports = YourConstructor.extend(mixinMethods, otherMixinMethods, {
        yetAnotherMethod: function () {
            // do something
        }
    });

    Now, when creating instances of the subclass, they'll have all the mixins while still passing instanceof checks for both the parent and the subclass.

    Modified to be standalone Common JS and to allow you to pass multiple extend objects by @HenrikJoreteg.
