Learning objectives

  • Master Fastify's modular architecture and advanced plugins
  • Implement JSON Schema validation with Ajv for robust APIs
  • Optimize performance via streaming, caching, and clustering
  • Develop unit, integration, and end-to-end tests
  • Secure APIs with JWT authentication, CORS, and rate limiting
  • Deploy to production with Docker, PM2, and cloud orchestration
  • Scale horizontally to support millions of requests

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 advanced Fastify mastery, your Node.js APIs risk 3x slower response times, leading to 40% user drop-offs and 25% revenue loss according to Stack Overflow studies.

  • Validation flaws expose to costly breaches (average 4M€/GDPR incident).

  • Without clustering optimization, scalability limited to 10k req/s blocks growth, as seen in 60% of startups failing on performance.

  • Lack of thorough tests multiplies production bugs x5, 20h/month downtime.

  • Insecure deployment via Express generates 30% OWASP vulnerabilities.

  • Investing 35h avoids these pitfalls, boosts performance 5x, secures revenue.

Program

Module 1Fastify Architecture: Advanced Plugins and Hooks (Modularity, Encapsulation)

Dive into refactoring an existing API into custom Fastify plugins, configure lifecycle hooks for logging and errors, perform exercises on dependency injection, produce a testable modular prototype, while measuring maintainability gains with tools like Pino for structured logs.

Module 2Validation and Serialization: JSON Schema, Ajv (Data Security)

Build complex JSON Schema for input/output validation, integrate Ajv with Fastify to reject malicious payloads, practice on real e-commerce API cases, generate optimized serialized responses, test robustness against SQL/NoSQL injections via interactive exercises.

Module 3Fastify Performance: Streaming, Caching, Compression (Mercurius Tools)

Optimize an API for 10x more throughput by implementing HTTP/2 streaming, enable Redis for distributed caching, configure Brotli/Gzip compression, analyze bottlenecks with clinic.js, develop a live benchmark comparing to Express, produce a performance report with 50% measured gains.

Module 4Testing and Debugging: Tap, Jest, Coverage (CI/CD Integration)

Write advanced test suites with Tap and Fastify inject, mock external services for isolation, achieve 90% coverage on a complete API, debug live with ndb, integrate with GitHub Actions for CI/CD, validate via a group project simulating a critical production bug.

Module 5Deployment and Security: Docker, PM2, JWT (Cloud Scaling)

Containerize your Fastify API with multi-stage Docker, deploy PM2 clusters for high availability, implement JWT/OAuth2 and rate limiting, secure Kubernetes Helm charts, simulate auto-scaling on AWS/Heroku, deliver a production-ready CI/CD pipeline with Prometheus monitoring.

Evaluation method

  • Daily interactive quizzes, final complete API project evaluation, recognized Qualiopi certification

Learning method

  • 70% hands-on on real projects, 30% applied theory, pair exercises, immediate feedback

Methods, materials and delivery

The Advanced Fastify Training - Ultra-Fast and Scalable APIs program is delivered onsite or remote (blended-learning, virtual classroom, remote presence). At Learni, an industry-certified training organization, every program is built to maximize skills acquisition regardless of the chosen format.

The trainer alternates between demonstrative, interrogative and active methods (through hands-on labs and/or scenarios). This pedagogical approach guarantees concrete learning that's immediately applicable at work.

Equipment required

For the smooth delivery of the Advanced Fastify Training - Ultra-Fast and Scalable APIs program, the following equipment is required:

  • Mac or PC computers, high-speed fiber internet, whiteboard or flipchart, projector or interactive touch screen (for remote sessions)
  • Training environments installed on workstations or accessible online
  • Course materials, hands-on exercises and complementary resources
  • Post-training access to materials and educational resources

For intra-company training on a site outside Learni, the client commits to providing all required teaching materials (computers, internet, etc.) for the smooth delivery of the program in line with the prerequisites in the communicated program.

* contact us for remote delivery feasibility** ratio varies depending on the program

Skills assessment methods

Assessment of skills acquired during the Advanced Fastify Training - Ultra-Fast and Scalable APIs program is performed through:

  • During training: case studies, hands-on labs and professional scenarios
  • End of training: self-assessment questionnaire and skills evaluation by the trainer
  • After training: completion certificate detailing acquired skills

Program accessibility

Learni is committed to making its programs accessible. All our programs are accessible to people with disabilities. Our teams are available to adapt the pedagogical methods to your specific needs. Please contact us for any adjustment request.

Enrollment terms and lead times

Registration is possible up to 48 business hours before the start of training. All our programs are eligible for corporate training budgets and employer-funded plans.

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.
