        user_id='...get from auth0...'>
    </auth0-button>

Your own login/logout labels

The login/logout text can be configured:

Optional one can add listeners on to get the profile (see also demo)

    loginButton.addEventListener("user-logged-in", (e) => {
        const userProfile = JSON.parse(e.detail);
        ...
    })

or to be notified of logout

   loginButton.addEventListener("user-logged-out", (e) => {
        const profile = JSON.parse(e.detail);
        alert(`User ${[profile.name]} logged out`)
   })

demo

this package contains a demo

download : https://github.com/kafkaacademy/auth0-spa-login

    cd demo

and edit the file index.html : add your domain and client_id.

and then :

    npm install
    npm start

Possible use in an SPA with a user defined menu (e.g. navbar):

In a nav bar environment you can make an html dialog around this login button.

At successfull login (listen to event 'user-logged-in') move the button from the dialog to the navbar as logout button.

This can be done by changing the html parent of the button from dialog to the navbar

In this way you do not need routers, to make all completely a real single page application.
