Architecture Overview

Most of the functionality in tota11y comes from its plugins. Each plugin gets its own directory in plugins/ and maintains its own JavaScript, CSS, and even handlebars. Here's what the simple LandmarksPlugin looks like.

plugins/shared/ contains a variety of shared utilities for the plugins, namely the info-panel and annotate modules, which are used to report accessibility violations on the screen.

index.js brings it all together.

tota11y uses a variety of technologies, including jQuery, webpack, babel, and JSX. There's no need to know all (or any!) of these to contribute to tota11y, but we hope tota11y is a good place to learn something new and interesting.

Testing

You can run unit tests on tota11y with the following:

npm test

Or lint with:

npm run lint

To perform manual testing as you work, you can run a live dev-server with the following:

Special thanks

Many of tota11y's features come straight from Google Chrome's Accessibility Developer Tools. We use this library heavily at Khan Academy.
