Dash Cognito Auth

Dash Cognito Auth

Dash Cognito Auth is a simple library using Cognito OAuth to authenticate and view a Dash app.

This Library uses Flask Dance and a modified version of Plotly's own dash auth for authentication.

This Library is heavily inspired by dash-google-oauth created by Lucas Chapin

Installation

$ pip install dash-cognito-auth

Basic Use

Authentication can be added to your Dash application using the CognitoOAuth class, i.e.

from dash import Dash
from flask import Flask
from dash_cognito_auth import CognitoOAuth

server = Flask(__name__)
server.config.update({
  'COGNITO_OAUTH_CLIENT_ID': ...,
  'COGNITO_OAUTH_CLIENT_SECRET': ...,
})

app = Dash(__name__, server=server, url_base_pathname="/")

additional_scopes = [...]
auth = CognitoOAuth(
   app,
   domain='mydomain',
   region='eu-west-1',
   additional_scopes,
   logout_url="/logout"
)

# your Dash app here :)
...

Example

This repository contains a simple Example App that demonstrates how to add Cognito authentication to your Dash app as well as the Login and Logout Flows.

Development

• Check out the repository
• Run pip install -r requirements.txt to install the package
• Run pip install -r requirements-dev.txt to install additional dependencies for running the tests
• If you want to run the Sample App or the end to end tests, it makes sense to deploy the Cloudformation Template in order to get a functioning User Pool + App Client
• Run the tests locally
  • Use python -m pytest tests --ignore-glob "*end_to_end*" to exclude the integration / end to end tests that require a Cognito Setup
  • Use python -m pytest tests to run all tests

Integration Tests

There are integration tests against a Cognito User Pool + App Client, if you want to run those - either create a .env file with this content or set the environment variables with the same name.

# Credentials for the user in the user pool
COGNITO_USER_NAME=<username>
COGNITO_EMAIL=<email-that-must-match>
COGNITO_PASSWORD=<password>

# Connection between the app and the user pool
COGNITO_DOMAIN=<just-the-prefix>
COGNITO_REGION=<aws-region-of-the-cognito-userpool>
COGNITO_OAUTH_CLIENT_ID=<app-client-id>
COGNITO_OAUTH_CLIENT_SECRET=<app-client-secret>
