Axe-core light

axe-core from Deque is a great accessibility library that is used by lots of Accessibility professionals around the world.

This repository contains patches and a build script to create a smaller version of the axe-core script.

This project is used by ExcellentWebCheck's Accessibility Platform to decrease both the size of axe.min.js as well as the output of axe-core.

Because the Accessibility report is passed via websockets, it makes sense to remove some of the unnecessary data. For ExcellentWebCheck's Accessibility Platform no messages and translations are needed because we provide our own.

Patches

The patches make the following adjustments:

• Remove all polyfills
• Support only the latest Chrome version
• Remove description, help, help_url and messages from the output.
• Remove metadata (url, timestamp, performance stats)

Result

	axe-core	axe-core light
File size	540K	423K
Output size (small sample page)	80.9K	46.6K

Note, we just stripped functionality and compatibility of axe-core and might not work for you! Also, axe-core already provides several options to reduce output such as skipping inapplicable, incomplete results etc.

Usage

./build.sh

Result can be found in: axe-core/axe.min.js
