This project provides a set of plugins that editors can include in articles to let readers control their experience.
This code is designed to work with Odyssey in ABC News environments, and as such is generally unsuitable for use in other projects. However it's published here in the hope others might be able to learn from the techniques used or pull out components for use in their own projects.
Allows readers to control autoplay sound in videos embedded within articles. This is a successor of the original odyssey audio visual plugin.
- Embed the Javascript document in your article (“[odyssey audio visual plugin]” - Content ID
#101718598) - then insert the plugin into your article with this marker:
#audio-visual-plugin-mount
This plugin integrates with Odyssey to enable audio in videos by default. The plugin also adds a class to the body should you want to develop a custom component:
const isAudioEnabled = document.body.classList.contains('is-audio-enabled');Allows readers to disable high-motion content within articles. This feature improves accessibility for sensory overload/vestibular disorders.
- Embed the Javascript document in your article (“[odyssey-reduced-motion-plugin]” - Content ID
#104109640) - then insert the plugin into your article with this marker:
#reduced-motion-plugin-mount
When this plugin is used, a class is added to the <body> on load and defaults to the reader's platform prefers-reduced-motion setting.
Devs should check the body for the applicable class rather than using the media query:
const prefersRedudcedMotion = document.body.classList.contains('is-reduced-motion');Or in CSS:
.is-reduced-motion .myThing{ animation: none; }An inverse class is-high-motion is also provided when reduced-motion isn't set.
This project uses Storybook where you can preview components, including light & dark variants: npm run storybook.
The audio visual plugin functionality is best tested in production using the Resource Override plugin, or by creating your own document to link to your development server: npm run dev.
All the plugins are bundled into the same script, but we have separate documents so we can track where the plugins are used. When releasing a new version, please update each CoreMedia documents.
