Learning objectives

  • Master Fastify's advanced architecture for high-performance APIs.
  • Implement hooks, plugins, and custom validation schemas.
  • Optimize horizontal scaling and critical error handling.
  • Integrate JWT authentication and advanced security against attacks.
  • Deploy Fastify microservices in production with monitoring.
  • Build a complete scalable and observable API project.

The Learni story

Founded by passionate learning and innovation experts, Learni's mission is to make professional training accessible to everyone, anywhere in the world. Our team operates in major hubs — London, New York, Boston — and internationally, to support talents and organizations in upskilling.

Don't let this gap widen

Why this program matters

  • 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.

Program

Module 1Fastify Architecture: Advanced Core, Hooks, and Schemas (Node.js, AJV)

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.

Module 2Plugins and Middleware: Logging, Serialization, Validation (Pino, Fastify-swagger)

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.

Module 3Security and Scaling: JWT, Rate Limiting, Clustering (Fastify-jwt, Redis)

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.

Module 4Deployment and Monitoring: Docker, PM2, Observability (Prometheus, Grafana)

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.

Evaluation method

  • Daily technical quizzes, graded practical workshops, final scalable API project, Qualiopi expert certification.

Learning method

  • 80% hands-on approach, real business cases, continuous feedback, live open-source tools.

Our method

Training quality, guaranteed at every step

Before, during, after: we frame the brief, introduce the trainer, tailor the content and measure impact. You stay in control from kickoff to wrap-up.

Step 1

Rigorous trainer selection

Each trainer is validated on three criteria: hands-on field expertise, proven pedagogy and alignment with your industry.

  • Triple validation: technical, pedagogical, sectoral.
  • Minimum rating 4.8/5 over the last 12 sessions.
Step 2

You meet the trainer beforehand

30-minute video call between you and the selected trainer to validate the fit, adjust content and clear any final doubts.

  • Live briefing on goals and team context.
  • Veto right — we swap the trainer for free if needed.
Step 3

Content tailored to your context

No recycled slides. The syllabus is reworked from your real cases: tools, constraints, vocabulary, ongoing projects.

  • Hands-on cases drawn from your stack and projects.
  • Program co-written then validated by your team.
Step 4

Continuous quality follow-up

Live evaluations, 30/90/180-day check-ins and a consolidation plan. If the impact misses the mark, we rework it.

  • NPS, knowledge quizzes and skills self-assessment.
  • Satisfaction guarantee: fully satisfied or free rework.

A simple promise: you don't pay to discover the trainer on day one. Everything is validated upfront, by you.
