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 🙏

A library that reads CoverageJSON documents and exposes them as Coverage data objects.

API docs

Usage

A browser version of this library is hosted on both jsDelivr and cdnjs, where the latter also hosts the unminified version together with source maps.

Usage is simple:

<script src="https://unpkg.com/covutils/covutils-lite.min.js"></script>
<script src="https://cdn.jsdelivr.net/covjson-reader/0.16/covjson-reader.min.js"></script>
<script>
CovJSON.read('http://example.com/coverage.covjson').then(function (cov) {
  // work with Coverage object
}).catch(function (e) {
  // there was an error when loading the coverage
  console.log(e)
})
</script>

The library makes use of the following ES2015 features: Promise, Symbol, Map, and Array.from. Depending on which browsers you need to support it may be necessary to include polyfills before loading this library.

NPM

This library can be used with browserify and similar tools by importing it via npm.

ES2015 syntax:

import * as CovJSON from 'covjson-reader'

CovJSON.read('http://example.com/coverage.covjson').then(cov => {
  // work with Coverage object
}).catch(e => {
  // there was an error when loading the coverage
  console.log(e)
})

This library is developed within the MELODIES project.
