@axe-core/reporter-earl

This project is a reporter for axe-core. When used as part of an axe-core run, it will produce results using the Evaluation And Reporting Language (EARL) 1.0. The reporter uses JSON-LD to serialise the RDF data.

Previous versions of this program were maintained at dequelabs/axe-reporter-earl.

Installation

To install Axe-reporter-earl, with NPM, run:

npm install @axe-core/reporter-earl

Usage

The EARL reporter can be passed to axe, either as part of configuration or as part of the run:

CommonJS Require Syntax:

const reporter = require('@axe-core/reporter-earl').default;
// Define the reporter through axe.configure
axe.configure({ reporter });
axe.run().then(earlResults => console.log(earlResults));
const reporter = require('@axe-core/reporter-earl').default;
// Use the reporter in a single axe.run call
axe.run({ reporter }).then(earlResults => console.log(earlResults));

ES6 Import Syntax:

import reporter from '@axe-core/reporter-earl';
// Define the reporter through axe.configure
axe.configure({ reporter });
axe.run().then(earlResults => console.log(earlResults));
import reporter from '@axe-core/reporter-earl';
// Use the reporter in a single axe.run call
axe.run({ reporter }).then(earlResults => console.log(earlResults));
