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)
})
