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 🙏

Readme

OpenCensus Web instrumentation for web performance APIs

Gitter chat

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

This package generates OpenCensus Web trace model spans based on performance API data provided by the browser. Specifically, it generates spans for the initial page load of a site based on the Resource Timing, Navigation Timing, and Long Task browser APIs. It attempts to gracefully degrade for older browsers that do not support those timing APIs, but it has not been tested yet for browser compatibility.

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 data. See the OpenCensus Web readme for details.

In the future we would like to support collecting spans for XHRs and other operations made after the initial page load and then join those back to the Resrouce Timing API information for more detailed network timings and events.
