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 🙏

What is this?

Ever taken a peek at the data blobs that get sent back and forth in WebRTC signalling? Yeah, that mess of line-oriented data is SDP. But sometimes you want to have that data available in JSON, like if you want to use XMPP Jingle for signalling.

This library will convert raw SDP into JSON that mirrors the structure of XMPP Jingle content, making it simple to convert the SDP data into an XMPP stanza with any of the various JS XMPP libraries, such as stanza.io, or xmpp-ftw.

And since you're working with WebRTC, be sure to check out simplewebrtc.

Installing

npm install sdp-jingle-json

Building bundled/minified version (for AMD, etc)

$ grunt

The bundled and minified files will be in the generated build directory.

How to use it

var sjj = require('sdp-jingle-json');

// I have SDP, but want JSON:
var json = sjj.toSessionJSON(sdpBlob, {
    creators: ['initiator', 'initiator'], // Who created the media contents
    role: 'initiator',   // Which side of the offer/answer are we acting as
    direction: 'outgoing' // Are we parsing SDP that we are sending or receiving?
});

// I have JSON (a dictionary of session and content descriptions), but want SDP:
var sdp = sjj.toSessionSDP(jsonSession, {
    role: 'responder',
    direction: 'incoming'
});

You can also use toMediaSDP and toMediaJSON to convert only a single media section.

See it in action

Open the convert.html file and enter in SDP or JSON to see how it converts back and forth.

Jingle JSON

The format for the generated JSON content is:
