Documentation at https://oaf-project.github.io/oaf-svelte-routing/

Features

Reset scroll and focus after PUSH and REPLACE navigation
Restore scroll and focus after POP navigation
Set the page title after navigation
Announce navigation to users of screen readers

In lieu of more details, see Oaf React Router for now. The features are basically the same.

Installation

# yarn
yarn add oaf-svelte-routing

# npm
npm install oaf-svelte-routing

Basic Usage

main.js:

import App from "./App.svelte";
+ import { globalHistory as history } from "svelte-routing/src/history";
+ import { wrapHistory } from "oaf-svelte-routing";

+ wrapHistory(history);

new App({
  target: document.getElementById("app"),
  hydrate: true
});

Advanced Usage

const settings = {
  announcementsDivId: "announcements",
  primaryFocusTarget: "main h1, [role=main] h1",
  // This assumes you're setting the document title via some other means.
  // If you're not, you should return a unique and descriptive page title for each page
  // from this function and set `setPageTitle` to true.
  documentTitle: (location) => document.title,
  // BYO localization
  navigationMessage: (title, location) => `Navigated to ${title}.`,
  shouldHandleAction: (previousLocation, nextLocation) => true,
  announcePageNavigation: true,
  setPageTitle: false,
  handleHashFragment: true,
  // Set this to true for smooth scrolling.
  // For browser compatibility you might want iamdustan's smoothscroll polyfill https://github.com/iamdustan/smoothscroll
  smoothScroll: false,
};

wrapHistory(history, settings);

A note on focus outlines

You may see focus outlines around your h1 elements (or elsewhere, per primaryFocusTarget) when using Oaf Svelte Routing.

You might be tempted to remove these focus outlines with something like the following:

[tabindex="-1"]:focus {
  outline: 0 !important;
}

Don't do this! Focus outlines are important for accessibility. See for example:

Note that Bootstrap 4 unfortunately removes these focus outlines. If you use Bootstrap, you can restore them with Oaf Bootstrap 4.
