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 this upskilling, your team accumulates a technological gap that translates directly into productivity loss.

  • Organizations that don't train their talents on key topics see their competitiveness drop.

  • Every quarter without training is a gap widening with competitors who invest.

  • The cost of inaction quickly exceeds that of well-targeted training.

Program

Module 1Express 2026 Fundamentals: Installation, Routing, and Middlewares (Node.js, Advanced Configurations)

Discover the evolutions of Express 2026 with quick installation via npm, configuration of a high-performance server, creation of dynamic routes, and custom middlewares for logging and authentication. Practice on concrete REST API cases, integrate data validators with Joi, test in real-time with Postman, and produce a first deployable functional prototype, while exploring Node.js optimizations for immediate scalability.

Module 2Advanced REST APIs with Express 2026: CRUD, Validation, and Pagination (Integrated Tools, Best Practices)

Dive into developing complete REST APIs under Express 2026, implement secure CRUD operations, manage request validation with express-validator, add intelligent pagination and sorting for large data volumes. Work on practical exercises with MongoDB databases via Mongoose, integrate lifecycle hooks for auditing, test endpoints with automated suites via Jest, and deliver a paginated API ready for enterprise production.

Module 3Express 2026 Security and Authentication: JWT, CORS, Rate Limiting (Secure Microservices)

Strengthen your Express 2026 APIs against common threats by implementing stateless JWT authentication, configuring advanced CORS for cross-origin frontends, enabling rate limiting with express-rate-limit, and helmets for secure headers. Apply these techniques to real microservices scenarios, practice simulated attacks like SQL injection and XSS, integrate OAuth2, and generate reports on fixed vulnerabilities, ensuring GDPR compliance for your professional projects.

Module 4Microservices and Scalability with Express 2026: Clustering, Messaging (Kafka, Redis for Resilience)

Design distributed microservices architectures with Express 2026, enable Node.js clustering for high availability, integrate Redis for caching and shared sessions, use Kafka for asynchronous messaging between services. Develop practical exercises for service discovery with Consul, test resilience under load with Artillery, monitor via Prometheus and Grafana, and deploy a scalable cluster simulating an enterprise ecosystem, with deliverables ready for Docker.

Module 5Deployment and Monitoring for Express 2026: Docker, CI/CD, Observability (PM2, New Relic)

Finalize your skills by deploying Express 2026 apps in production via Docker and basic Kubernetes, configure CI/CD with GitHub Actions, integrate PM2 for process management and New Relic for real-time monitoring. Practice zero-downtime deployments, analyze logs with Winston and ELK stack, optimize performance under high traffic, and produce a complete pipeline with observability dashboard, certifying your skills for critical professional environments.

Evaluation method

  • Daily interactive quizzes on Express 2026 concepts
  • Final project: Complete deployed microservices API
  • Company case study with personalized feedback
  • Qualiopi certification on acquired skills

Learning method

  • 70% hands-on on real Express 2026 projects
  • Adaptive pedagogy in small groups of max 10
  • Video support and post-training resources for 6 months
  • Pair exercises for immediate feedback

Methods, materials and delivery

The Training Express 2026 - Developing 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 Training Express 2026 - Developing 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 Training Express 2026 - Developing 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.

Enrollment terms and lead times

Learni programs are available inter-company and intra-company, onsite or remote. Enrollments are possible up to 48 business hours before the program starts. Our programs are eligible for corporate funding paths. Contact us to discuss your training project and funding options.

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.
