fastify-passport

fastify-passport integrates the Passport.js authentication middleware ecosystem into Fastify applications, enabling developers to use over 500 strategies (like OAuth, JWT, or local login) with Fastify’s high-performance, plugin-based architecture. It is designed for Node.js developers building secure, scalable APIs or web apps who want the flexibility of Passport without sacrificing Fastify’s speed and request lifecycle. This project is interesting because it bridges two popular ecosystems, solving a critical security need while maintaining the low overhead that makes Fastify a compelling alternative to Express.
