RunKit +

Try any Node.js package right in your browser

This is a playground to test code. It runs a full Node.js environment and already has all of npm’s 1,000,000+ packages pre-installed, including code-coverage with all npm packages installed. Try it out:

var codeCoverage = require("code-coverage")

all documents on RunKit are public
require() any package directly from npm
use arrow functions, classes, template strings, and most of ES6
await any promise instead of using callbacks (example)
create your own embedded node.js snippets

This service is provided by RunKit and is not affiliated with npm, Inc or the package authors.

code-coverage v0.0.2

Find unused CSS and JS code. When you load or run a page, the app tells you how much code was used, versus how much was loaded. You can reduce the size of your pages by only shipping the code that you need
