Logout button

[T4rk1n]

Add a logout and create_logout_button methods to PlotlyAuth.

• logout
  • Must be called from a callback, takes no arguments.
  • Invalidate the plotly_oauth_token.
  • Clear the auth cookies.
• create_logout_button
  • Returns a logout button component to use in a dash layout.
  • Call logout once clicked then redirect.
  • Options:
    • label: The text (or children component) on the button (default='Logout').
    • redirect_to: Redirect the browser to this link when the button is clicked (default='https://plot.ly).
  • Also takes props keywords from html.Button like style, className, etc.

Example:

import dash
import dash_auth

import dash_html_components as html

app = dash.Dash(__name__)

auth = dash_auth.PlotlyAuth(
    app, 'logout', 'public',
    'http://localhost:8050/')

btn_style = {
    'backgroundColor': 'red',
    'padding': '16px',
    'borderRadius': '8px',
    'border': 'none'
}

app.layout = html.Div([
    html.Div('content', id='content'),
    auth.create_logout_button(
        style=btn_style,
        label='Sign out',
        redirect_to='https://www.google.com')
])

if __name__ == '__main__':
    app.run_server()

Looks good, thanks for adding a 🐀 test!

Other than the default redirect, there are a couple of minor issues with the commits themselves that I'd like you to fix before merging:

• The email address you used <philippe@plot.ly> doesn't match an email address that GitHub knows about. Either add this email address to the T4rk1n account on GitHub, or rebase your commits to change the author to an email address that is associated with that account.
• 66b87d3 is a fix to a previous commit, so please rebase to get rid of it.

We should redirect to the root of the app by default.

@scjody I was wondering why the commits didn't show my profile picture, added the email thanks.
