express‑jwt‑fusionauth is an Express middleware library that handles JWT‑based authentication against a FusionAuth identity server. It extracts, validates and refreshes access tokens, redirects browsers to the FusionAuth login flow when needed, enforces application‑specific role checks, and provides a handler for the OAuth 2.0 redirect endpoint to exchange authorization codes for tokens. It is aimed at Node.js/Express developers who want a simple, FusionAuth‑focused way to secure APIs and web apps.
