Without Fastify mastery, your Node.js APIs top out at 500 req/s, generating response times 3x slower than competitors, AWS costs doubled (up to 10k€/year for medium traffic), 30% customer churn due to scaling outages, JWT vulnerabilities exposing to costly breaches (average 4M€), and 20% market share loss to lightweight frameworks.
Invest 28 hours to divide your latencies by 5, scale to 50k req/s without crashes, secure 100% of endpoints, and break even in 1 month with ultra-efficient APIs.
The Fastify Expert Training - Ultra-High-Performance and Scalable APIs training is delivered in-person or remotely (blended-learning, e-learning, virtual classroom, remote in-person). At Learni, a Qualiopi-certified training organization, each program is designed to maximize skills acquisition, regardless of the training mode chosen.
The trainer alternates between demonstrative, interrogative, and active methods (through practical exercises and/or real-world scenarios). This pedagogical approach ensures concrete and directly applicable learning in the workplace.
To ensure the quality of the Fastify Expert Training - Ultra-High-Performance and Scalable APIs training, Learni provides the following teaching resources:
For in-house training at a location external to Learni, the client ensures and commits to having all necessary teaching materials (IT equipment, internet connection...) for the proper conduct of the training action in accordance with the prerequisites indicated in the communicated training program.

Dive into Fastify's core by setting up an optimized server, implement custom lifecycle hooks for request logging, validate complex payloads with AJV and JSON schemas, perform exercises on asynchronous error handling, produce your first reusable plugin, while benchmarking performance gains against Express to boost your APIs from day 1.
Develop advanced plugins to integrate structured logging with Pino, configure fast JSON serialization, test automatic route validation with Swagger, chain practical workshops on real e-commerce API cases, generate interactive API documentation, measure 40% reduced latencies, and leave with deploy-ready modules for your projects.
Secure your APIs with advanced JWT and Redis rate limiting, implement native clustering for horizontal scaling, simulate DDoS attacks in exercises, optimize DB connections with async hooks, build a resilient microservice handling 10k req/s, analyze live metrics, and depart with proven production anti-vulnerability strategies.
Containerize your Fastify API with Docker, deploy with PM2 and Kubernetes basics, integrate Prometheus for monitoring, complete a full scalable API project, load test with Artillery, generate Grafana dashboards, measure 50% cloud cost reductions ROI, and conclude with a validated expert certificate.
