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 🙏

Symple Client

The Symple JavaScript client is a client-side implementation of the Symple protocol that runs in the web browser.

What is Symple?

Symple is an unrestrictive real time messaging and presence protocol that implements the minimum number of features required to build full fledged messaging applications with security, flexibility, performance and scalability in mind. These features include:

  • Session sharing with any backend (via Redis)
  • User rostering and presence
  • Media streaming (via WebRTC, see demo)
  • Scoped messaging ie. direct, user and group scope
  • Real-time commands and events
  • Real-time forms

Symple currently has client implementations in JavaScript, Ruby and C++, which make it ideal for a wide range of messaging requirements, such as building real-time games and applications that run in the web browser, desktop, and mobile phone.

Installation

# install the server
npm install symple

# install the client
npm install symple-client

Demo

We've included a fully featured video chat demo using Symple and WebRTC for your hacking pleasure. The source code is located in the symple-webrtc-video-chat-demo repository.

You can see it live here: http://symple.sourcey.com

Usage

The first thing to do is fire up the server:

cd /path/to/symple/server

node server

To use Symple in your app just add the following two scripts into your HTML head, replacing the src path with the correct script locations as necessary.

Note: Socket.IO is the only dependency (1.3.7 at the time of writing).

  <script type="text/javascript" src="socket.io.js"></script>
  <script type="text/javascript" src="symple.min.js"></script>

The next thing is to instantiate the client. The code below should provide you with a solid starting point, and illustrates the available callback API methods:

client = new Symple.Client({
  token: 'someauthtoken',        // An optional pre-arranged session token  
  url: 'http://localhost:4500',  // Symple server URL [http/https]  
  peer: {                        // Peer object contains user information  
    name: 'My Name',             // User display name  
    user: 'myusername',          // User ID  
    group: 'somegroup',          // Peer group/room this user's communication is restricted to  

    // Note: The peer object may be extended any custom data, which will  
    // automatically be broadcast to other group peers via presence updates.  
  }
});

client.on('announce', function(peer) {
  console.log('announce:', peer)

  // The user has successfully authenticated
});

client.on('presence', function(p) {
  console.log('presence:', p)

  // Captures a presence message broadcast by a peer
});

client.on('message', function(m) {
  console.log('message:', m)

  // Captures a message broadcast by a peer
});

client.on('command', function(c) {
  console.log('command:', c)

  // Captures a command send from a remote peer
});

client.on('event', function(e) {  
  console.log('event:', e)    

  // Captures an event broadcast from a remote peer
});

client.on('error', function(error, message) {
  console.log('connection error:', error, message)

  // Connection or authentication failed
  if (error == 'connect') {
  	// Authentication failed
  }
  else if (error == 'connect') {
  	// Connection failed
  }
});

client.on('disconnect', function() {
  console.log('disconnected')

  // Disconnected from the server
});

client.on('addPeer', function(peer) {
  console.log('add peer:', peer)  

  // A peer connected       
});

client.on('removePeer', function(peer) {
  console.log('remove peer:', peer)

  // A peer disconnected  
});

Now all that's left is to build your awesome app!
