appHistory polyfill

⚠️ Not for production. Use at your own risk; there will be breaking changes because the spec is not yet finalized ⚠️

A work-in-progress polyfill for the appHistory proposal.

Usage

This polyfill must run in a browser-like environment (e.g. an env that has window.location and window.history). If there's time, and demand for it, I think it would be interesting to have a discussion about how this polyfill could work in other environments.

To setup the polyfill so that it will automatically listen for anchor tag clicks, do the following:

import { useBrowerPolyfill } from "@frehner/apphistory";
userBrowserPolyfill();

// appHistory is now on the window
window.appHistory.push();

Alternatively, you can create your own instance of AppHistory:

import { AppHistory } from "@frehner/apphistory";
const appHistory = new AppHistory();

// use your own instance of appHistory, without any events from things like anchor tags
appHistory.push();

Differences

• The events for an AppHistoryEntry use event.detail.target instead of event.target to get access to the AppHistoryEntry that fired the event.
