Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

extendible

From bigpipe.ioVersion npmBuild StatusDependenciesCoverage Status

Extend your JavaScript constructor in the same way as would extend Backbone.js Models using the extend method. Extending and inheritance has never been easier and more developer friendly. While the original version was straight port of the Backbone's source it has been re factored and rewritten many times to the project it is today. It features:

  • Backbone compatible extend API.
  • Support for EcmaScript 5 getters and setters.
  • Understands the difference between constructors that are created in use strict mode.

Installation

The module is intended for server-side and browser usage. We use feature detection to ensure compatibility with EcmaScript 3 based environments. The module is distributed through npm and can be installed using:

npm install --save extendible

Usage

In all example code we assume that you've already required the extendible module and saved it as the extend variable as shown in the following example:

var extend = require('extendible');

The extend method should be on the constructor as .extend method:

function Word() {
  this.foo = 'bar';
}

//
// It should be added on the constructor, not as property on the prototype!
//
Word.extend = extend;

To create a new Foo class of your own you call the Foo.extend method with 2 arguments:

  1. Object properties and methods that should be added to your extended class prototype. These will override existing properties, but it would not override the properties on the parent/root class that you extend on.
  2. Object properties and methods that should added on the constructor directly. So instead of being introduced on the .prototype it's directly added to the returned Function.

As the properties of the prototype and constructor are inherited from the parent/root constructor you can further extended using the same extend method:

var Hello = Word.extend({
  name: 'hello',
  say: function update() {
    console.log('the word is: '+ this.name);
  }
});

var World = Hello.extend({
  name: 'world'
});

var world = new World();
world.say(); // 'the word is: world'
