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.


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 🙏

node.js framework to prototype and scale rapidly

node framework to prototype and scale API servers rapidly.


SR.API.add('HelloWorld', {
	name: 'string'
}, function (args, onDone) {
	LOG.warn('HelloWorld called with: ' + args);	
	onDone(null, {hello:});

var l_frontier = new SR.Frontier(37070);

Then called at server:

SR.API.HelloWorld({name: 'John'}, function (err, result) {
	LOG.debug('positive test result: ');
	if (err) {
		return LOG.error(err);

Or at clients:

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

var onConnect = function () {

	SR.API.HelloWorld({name: 'world'}, function (err, result) {
		if (err) {
			return alert(err);
		document.write('Hello: ' + result.hello);


Or request from URL:


$ npm install scalra

see Installation Guide for full instructions to setup a Scalra system on empty systems.


  • Write one API logic for any connection types (HTTP/HTTPS/websocket/socket)
  • Logic is called in the same style at both client and server
  • Shared sessions between HTTP and WebSocket requests
  • Publish / subscribe (pub/sub) as messaging layer
  • Auto-reload of modified logic scripts
  • Works out-of-box with MongoDB and Express
  • In-memory DataStore that access and update DB data simply as variables

see Release Notes on various changes / new features in each releases.

Quick Start

Simply copy the demo project under /demo as your own project

$ npm install scalra
$ cp -R node_modules/scalra/demo /tmp/foo && cd /tmp/foo

Install dependencies:

$ npm install scalra

Start the server:

$ npm start

Verify server is up with:


Scalra is designed to allow server developers to focus on logic development instead of networking or server management issues. Once developed using the Scalra framework, the server's reliability, security, and scalability is automatically covered without having to worry about re-writing code when the service is under heavy workload.

Additional functionalities can be added with pluggable Scalra modules.
