azure-auth
Microsoft Entra ID (Azure AD) authentication for React SPAs with MSAL.js and Cloudflare Workers backend JWT validation. Full-stack pattern: MSAL React for frontend auth flows, jose library for Workers token validation (MSAL.js doesn't work in Workers).CRITICAL: Azure AD JWKS endpoint is NOT at standard .well-known/jwks.json - must fetch from openid-configuration first. MSAL v3.0.23 + msal-browser v4.27.0 use Authorization Code Flow with PKCE (no implicit flow).Use when: implementing Microsoft/Azure AD SSO, troubleshooting AADSTS50058 infinite loops, AADSTS700084 refresh token expired, React Router v6 redirect loops, NextJS no_cached_authority_error, or validating Entra ID tokens in Cloudflare Workers.
