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 🙏

v8-to-istanbul

Build Status Conventional Commits nycrc config on GitHub

converts from v8 coverage format to istanbul's coverage format.

Usage

const v8toIstanbul = require('v8-to-istanbul')
// the path to the original source-file is required, as its contents are
// used during the conversion algorithm.
const converter = v8toIstanbul('./path-to-instrumented-file.js')
await converter.load() // this is required due to async file reading.
// provide an array of coverage information in v8 format.
converter.applyCoverage([
  {
    "functionName": "",
    "ranges": [
      {
        "startOffset": 0,
        "endOffset": 520,
        "count": 1
      }
    ],
    "isBlockCoverage": true
  },
  // ...
])
// output coverage information in a form that can
// be consumed by Istanbul.
console.info(JSON.stringify(converter.toIstanbul()))

Ignoring Uncovered Lines

Sometimes you might find yourself wanting to ignore uncovered lines in your application (for example, perhaps you run your tests in Linux, but there's code that only executes on Windows).

To ignore lines, use the special comment /* v8 ignore next */.

NOTE: Before version 9.2.0 the ignore hint had to contain c8 keyword, e.g. /* c8 ignore ....

ignoring the next line

const myVariable = 99
/* v8 ignore next */
if (process.platform === 'win32') console.info('hello world')

ignoring the next N lines

const myVariable = 99
/* v8 ignore next 3 */
if (process.platform === 'win32') {
  console.info('hello world')
}

ignoring all lines until told

/* v8 ignore start */
function dontMindMe() {
  // ...
}
/* v8 ignore stop */

ignoring the same line as the comment

const myVariable = 99
const os = process.platform === 'darwin' ? 'OSXy' /* v8 ignore next */ : 'Windowsy' 

Testing

To execute tests, simply run:

npm test
