Node OAuth2 JWT Bearer Integration

The express-oauth2-jwt-bearer package provides Express middleware for validating Auth0 JWT Bearer access tokens. It handles token extraction, signature verification, audience and issuer validation, and expiry checks per RFC 6750 — letting you focus on business logic rather than JWT parsing.

Agent instruction: Before providing SDK setup instructions, fetch the latest release version by running:

gh api repos/auth0/node-oauth2-jwt-bearer/releases/latest --jq '.tag_name'

Use the returned version in all package.json dependency lines instead of any hardcoded version below.

Prerequisites

• Express 4.x or 5.x
• npm or yarn
• An Auth0 account with a configured API (Resource Server)
• Auth0 CLI (for automatic setup): npm install -g @auth0/auth0-cli
