static-extend NPM version NPM downloads Build Status

Adds a static extend method to a class, to simplify inheritance. Extends the static properties, prototype properties, and descriptors from a Parent constructor onto Child constructors.

Install

Install with npm:

$ npm install static-extend --save

Usage

var extend = require('static-extend');

API

Returns a function for extending the static properties, prototype properties, and descriptors from the Parent constructor onto Child constructors.

Params

  • Parent {Function}: Parent ctor
  • extendFn {Function}: Optional extend function for handling any necessary custom merging. Useful when updating methods that require a specific prototype.
  • Child {Function}: Child ctor
  • proto {Object}: Optionally pass additional prototype properties to inherit.
  • returns {Object}

Example

var extend = require('static-extend');
Parent.extend = extend(Parent);

// optionally pass a custom merge function as the second arg
Parent.extend = extend(Parent, function(Child) {
  Child.prototype.mixin = function(key, val) {
    Child.prototype[key] = val;
  };
});

// extend "child" constructors
Parent.extend(Child);

// optionally define prototype methods as the second arg
Parent.extend(Child, {
  foo: function() {},
  bar: function() {}
});
