Babel-Node & React SAML SSO Implementation

See corresponding tutorial here.

Requirements

  • node.js (I used v13.14.1)
  • yarn or npm

Deployment Instructions

  1. Register your app with an IdP.
  2. Fill in the following constants in ./server/src/constants.js in order to point to your IdP.
    • SAML_SSO_URL
    • SAML_ACS_URL
    • SAML_CERT
  3. Navigate to ./dashboard.
  4. Run yarn install to install necessary packages for React rendering.
  5. Run yarn start and navigate to http://localhost:8080/ to test the client-side app. User data should fail to fetch. Stop the command.
  6. Run yarn build to bundle the app using Webpack. This will create the folder ./server/public.
  7. Navigate to ./server.
  8. Run yarn install to install necessary packages for React rendering.
  9. Deploy the server package (./server) somewhere that will give you a publicly accessible URL.
  10. Set REDIRECT = false in ./server/src/routes/saml.js.
  11. Run yarn start and navigate to http://localhost:9090/ to test the served react app. You should be redirected to login through the IdP, and then redirected back to your localhost app once completed.

Implementation Notes

  • I chose to use the server to access the user's cookies instead of letting the client. This is safer because it helps protect against XSS attacks.
