get-jwks

Fetch utility for JSON Web Key Sets (JWKS) with caching, issuer validation, and provider discovery. Current stable version: 11.0.3, requires Node.js >=20, ships TypeScript types. Uses lru-cache for key caching and supports OpenID Connect Discovery. Differentiators: built-in stale cache fallback on errors, configurable issuer whitelist/check, and fetch options customization. ESM-only since v10. Common alternatives: jwks-rsa (more features), this package is leaner for serverless.
