CRA SPA with Auth0 and Server for User Session and CSRF Protection

This is a simple POC for a Single Page Application (CRA) with 0Auth Login and an express server to manage a user session.

Motivations

  • Use secure session cookie instead of JWT token for authentication and user session management in the browser.
  • Use an OAuth flow for user login process while doing the above (connect to a third party service such as Auth0).

Auth and Access Flow

Auth and Access Flow

Advantages

  • More secure with secure session cookie than jwt in browser
  • Can manage user session (can list, analyse, revoke sessions) - potentially OAuth flow may not be required.
  • Could potentially look at the possibility of serverless for both server and store.

Disadvantages

  • More complicated than just JWT in case of using OAuth
  • Extra server layer required for session management

Further Investigation Required

  • Does this work with Webpack Module Federation?

POC Demo Application

Components

  • Single Page Application (Create React App)
  • Express (Nodejs) Server

How to run the app

  1. clone this repo.
  2. Populate .env.example with your auth0 application credentials/details and rename it .env.
  3. yarn install
  4. yarn run build to build the app.
  5. yarn run start to start the application after the build is finished.
  6. Visit http://localhost:3000
