Swup A11y Plugin
Enhance the accessibility of your swup-powered sites.
Loading new content via AJAX is great UX for most users, but comes with serious shortcomings for screen reader users. We can improve the experience for everybody if we:
- Announce page visits to screenreaders by reading the new page title
- Focus the main content area after swapping out the content
That's exactly what this plugin does.
Installation
This plugin can be installed with npm
npm install swup-a11y-plugin
and included with import
import SwupA11yPlugin from 'swup-a11y-plugin';
or included from the dist folder
Usage
To run this plugin, include an instance in the swup options.
const swup = plugins: ;
Markup
The plugin should work out of the box if you use proper semantic markup for your
content, i.e. main
for your content area and h1
or h2
for your headings.
Logo <!-- will be focussed --> Page Title <!-- will be announced --> Lorem ipsum dolor sit amet
Options
All options with their default values:
contentSelector: 'main' headingSelector: 'h1, h2, [role=heading]' announcementTemplate: 'Navigated to: {title}' urlTemplate: 'New page at {url}'
contentSelector
The selector for matching the main content area of the page.
This area will receive focus after a new page was loaded.
headingSelector
The selector for finding headings inside the main content area.
The first heading's content will be read to screen readers after a new page was loaded.
announcementTemplate
How to announce the new page title.
urlTemplate
How to announce the new page url. Only used as fallback if neither a title tag nor a heading were found.
