Learning objectives

  • Design scalable RESTful and GraphQL API architectures with Express.
  • Implement custom middlewares for authentication and advanced logging.
  • Optimize performance via clustering, Redis caching, and load balancing.
  • Integrate unit and integration tests with Jest and Supertest.
  • Deploy Express applications on Docker and Kubernetes in production.
  • Manage errors and OWASP security with rate limiting and Joi validation.
  • Rapid prototyping of interoperable microservices.

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 Express expertise, your APIs saturate at 1000 req/s, causing 30% customer churn due to latency frustrations.

  • OWASP security breaches expose 40% of user data, generating GDPR fines up to 4% of revenue.

  • Manual deploys fail 70% of the time, delaying product launches by weeks.

  • Unoptimized performance inflates cloud costs x3, AWS bills explode.

  • Competitors on Next.js/Express scale 10x better, leaving you 25% market share behind.

  • Invest 28h to avoid 50k€ annual losses, transform vulnerabilities into competitive advantages tomorrow.

Program

Module 1Advanced Routing and Middlewares: Structuring Robust APIs (Express Router, Helmet, CORS)

Dive into refactoring your routing with Express Router for modular APIs, configure custom middlewares for JWT authentication and structured logging with Winston, complete exercises on real e-commerce cases, build a secure user API prototype, test data flows live, gain fluidity and scalability from the first session.

Module 2Performance and Optimization: Accelerate Express (Clustering, Redis, Compression)

Master native Node clustering for multi-core usage, integrate Redis for intelligent caching and distributed sessions, apply Gzip compression to heavy APIs, simulate loads with Artillery to identify bottlenecks, optimize concrete analytics dashboard cases, generate before/after performance reports, feel the immediate acceleration of your apps.

Module 3Security and Testing: Fortify Your APIs (Rate Limiting, Joi, Jest/Supertest)

Strengthen security with Express-rate-limit rate limiting and strict Joi validation, implement OWASP top 10 protections via dedicated middlewares, write end-to-end tests with Supertest and Jest, challenge SQLi/XSS attack scenarios on vulnerable APIs, produce a test suite with 90% coverage, validate defenses in groups, leave with an impenetrable API.

Module 4Deployment and Microservices: Production-Ready (Docker, Kubernetes, PM2)

Containerize your Express apps with multi-stage Docker, orchestrate on Kubernetes for auto-scaling, deploy via PM2 in cluster mode, integrate CI/CD GitHub Actions for microservices, migrate a monolith to decomposed services live, generate production-ready Helm charts and manifests, celebrate zero-downtime deployment, launch your projects with confidence.

Evaluation method

  • Daily interactive quizzes on key concepts.
  • Graded practical exercises with real-time feedback.
  • Final project: Complete API deployed, evaluated on performance and security.

Learning method

  • 80% hands-on pedagogy via collaborative Zoom workshops.
  • Real cases from Fortune 500 companies adapted to your needs.
  • Resources: private Git repo, unlimited replay videos.

Methods, materials and delivery

The Express Training - Develop Scalable and Secure APIs program is delivered onsite or remote (blended-learning, e-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 Express Training - Develop Scalable and Secure 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 Express Training - Develop Scalable and Secure 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.

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.
