Accessibility Plugin

by daun

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.


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

<script src="./dist/SwupA11yPlugin.js"></script>


To run this plugin, include an instance in the swup options.

const swup = new Swup({
  plugins: [new SwupA11yPlugin()]


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.

<main> <!-- will be focussed -->
  <h1>Page Title</h1> <!-- will be announced -->
  <p>Lorem ipsum dolor sit amet</p>


All options with their default values:

  contentSelector: 'main',
  headingSelector: 'h1, h2, [role=heading]',
  announcementTemplate: 'Navigated to: {title}',
  urlTemplate: 'New page at {url}'


The selector for matching the main content area of the page.

This area will receive focus after a new page was loaded.


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.

How to announce the new page url. Only used as fallback if neither a title tag nor a heading were found.
