React/Express Starter App

A walkthrough demonstrates how to build a React and Express B2B application using PropelAuth for hosted authentication, user management, and organization features. It covers creating and branding a PropelAuth project, configuring optional social login and B2B settings, registering a test user, and integrating the React SDK through an AuthProvider, routing, login, signup, logout, and protected user-information views. The frontend retrieves authentication state, user data, and access tokens, then sends authenticated requests with Bearer tokens to an Express backend, with a proxy configuration used to address local CORS concerns. On the server, PropelAuth’s Express middleware validates JWT access tokens, exposes authenticated user information through protected routes, and can reject unauthenticated requests with a 401 response. The guide also adds organization support by listing a user’s organizations, enabling organization creation or invitations, displaying organization details, and using membership middleware to ensure users can access only organizations to which they belong.
