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.

OpenCensus Trace Context format propagation for web browsers

For overview and usage info see the main OpenCensus Web readme.

OpenCensus Trace Context format propagation provides utilities to serialize and deserialize a trace context header in the W3C Trace Context format.

The library is in alpha stage and the API is subject to change.

Usage

Currently the primary intended usage of OpenCensus Web is to collect spans from the resource timing waterfall of an initial page load and trace on-page user interactions with a series of features like automatic tracing for clicks and route transitions, custom spans, and browser [Performance API][performance-api] data. See the OpenCensus Web readme for details.

This package is currently used to deserialize the window.traceparent global variable that the server can send back to the client to indicate the parent trace context for the initial page load.

This is also used to propagate trace contextspans for XHRs in the user interactions, serializing a traceparent header to send along to XHR calls.
