SPA using the Token Handler Pattern

A Single Page Application (SPA) that implements OpenID Connect using recommended browser security.
The SPA uses a Backend for Frontend (BFF) approach, in line with best practices for browser based apps.

A modern evolution of Backend for Frontend is used, called the Token Handler Pattern.
The SPA uses an OAuth Agent to perform an API driven OpenID Connect flow:

Architecture Benefits

This provides the best separation of web and API concerns, to maintain all of the benefits of an SPA architecture:

• Strongest Browser Security, with only SameSite=strict cookies
• Great User Experience due to the separation of Web and API concerns
• Productive Developer Experience with only simple security code needed in the SPA
• Deploy Anywhere, such as to a Content Delivery Network

Simple Code in Apps

This repository demonstrates the business focused components companies should need to develop:

• A Single Page App coded in React
• A Web Host to provide static content
• An API that validates JWT access tokens

The token handler components should be developed by Curity or another provider, then plugged in.

Run the End-to-end Flow

The SPA can be quickly run in an end-to-end flow on a development computer by following these guides:

• Standard SPA using an Authorization Code Flow (PKCE) and a Client Secret
• Financial-grade SPA using Mutual TLS, PAR and JARM

Website Documentation

See the Curity OAuth for Web Home Page for detailed documentation on this design pattern.
