Provide session or sessionInfo to onLogin callback

Search terms you've used

session, sessionInfo, onLogin

Impacted environment

In which environment would the proposed feature apply ?

• The browser
• Node.js (Though mostly the browser)
• Other (please specify): ...
• I'm not sure.

Feature suggestion

When using the default session, it would be nice if I could access the sessionInfo, or possibly even the entire session, from the callback handler passed to onLogin.

Expected functionality/enhancement

import { onLogin } from "@inrupt/solid-client-authn-browser";

onLogin((sessionInfo) => {
    console.log("This should be a safe operation:", sessionInfo.webId);
});

Actual functionality/enhancement

Currently you have to add another call to getDefaultSession() in the callback, and a type checker cannot statically verify that its webId property is set and isLoggedIn is true.

Use Cases

I've got a central place in my app that keeps track of the user's session, and I update it whenever a login or logout event is thrown.

Additional information

N/A

Start by tracing the onLogin callback and getDefaultSession entry points in the TypeScript authentication code, then inspect how sessionInfo and the default session are typed. Define the callback contract so it receives the requested session information, and verify that the webId and logged-in state are represented safely for login handlers.
