Plotly Dash plugin to allow authentication through 3rd party OAuth providers.

Overview

build

dash-auth-external

Integrate your dashboards with 3rd parties and external OAuth providers.

Overview

Do you want to build a Plotly Dash app which pulls user data from Google, Spotify, Slack etc?

Dash-auth-external provides a simple interface to authenticate users through OAuth2 code flow. Allowing developers to serve user tailored content.

Installation

Dash-auth-external is distributed via PyPi

pip install dash-auth-external

Simple Usage

#using spotify as an example
AUTH_URL = "https://accounts.spotify.com/authorize"
TOKEN_URL = "https://accounts.spotify.com/api/token"
CLIENT_ID = "YOUR_CLIENT_ID"

# creating the instance of our auth class
auth = DashAuthExternal(AUTH_URL, TOKEN_URL, CLIENT_ID)

We then pass the flask server from this object to dash on init.

app = Dash(__name__, server= auth.server)

That's it! You can now define your layout and callbacks as usual.

To obtain your access token, call the get_token method of your Auth object. NOTE This can ONLY be done in the context of a dash callback.

app.layout = html.Div(
[
html.Div(id="example-output"), 
dcc.Input(id="example-input")
])

@app.callback(
Output("example-output", "children"),
Input("example-input", "value")
)
def example_callback(value):
    token = (
        auth.get_token()
    )  ##The token can only be retrieved in the context of a dash callback
    return token

    Outdated PYPI

    Hi, I noticed that the master branch differs from the pypi version, when using the pypi version there is a dict error that appears which is resolved in the GitHub branch. Could you update the pypi version as well? Lastly, I keep getting a key error but as far as I can tell my token field name is correct. I am using O2Auth with openID connect.

    token = auth.get_token()
    File "auth.py", line 27, in get_token
    raise KeyError(
    KeyError: 'Header with name access_token not found in the flask request headers.'
    

    Here is my method:

    auth = DashAuthExternal(
                            external_auth_url= AUTH_URL,
                            external_token_url= TOKEN_URL,
                            client_id= CLIENT_ID,
                            with_pkce=True,
                            app_url= "http://127.0.0.1:8050",
                            redirect_suffix = "/redirect",
                            auth_suffix = "/",
                            home_suffix="/app",
                            client_secret= CLIENT_SECRET,
                            _secret_key= None,
                            auth_request_headers= None,
                            token_request_headers= None,
                            scope= ("openid profile"),
                            )
    

    Could the error be caused by anything other than an incorrect token field name?

    I also am getting this error if I try to go to /redirect after already authenticating, I am not sure if it is relevant or normal behavior after authentication.

    File "/dash_auth_external/routes.py", line 76, in build_token_body
    code = redirect_params["code"][0]
    KeyError: 'code'

    Response headers in dash-2.4 is not a dictionary but Headers. It also not ideal to override the member but amend values.
