Why this program matters

  • Without expert WebSocket mastery, your real-time apps risk latencies over 500ms, causing 40% user drop-offs according to Stack Overflow studies.

  • WSS security breaches expose to DDoS attacks, with 25% of incidents reported by OWASP.

  • Faulty scaling leads to crashes under 10k simultaneous connections, losing up to 200k€/an in revenue for SaaS.

  • Junior developers waste 3x more time debugging without optimized protocols.

  • Invest 14h to avoid these pitfalls, scale to millions of users, and dominate the real-time market.

Program

WebSocket curriculum: 2 modules over 2 days

Module 1 : Advanced WebSocket Fundamentals: Handshakes, Framing, Node.js Tools (ws, Socket.io)

Dive into the WebSocket protocol by coding custom handshakes, manage binary framing with Node.js and the ws library exercises, test multiplexed real-time messages via Socket.io, analyze scalable chat case studies, build a functional prototype with detailed logs, while mastering HTTP fallbacks for optimal resilience.

Module 2 : WebSocket Optimization and Scaling: WSS Security, Load Balancing, Deployments (Docker, AWS)

Advance to expertise by securing WSS connections with TLS and JWT, scale via Redis Pub/Sub and NGINX load balancer in practical workshops, integrate with React frontends for live dashboards, deploy on Docker Swarm with Prometheus monitoring, resolve massive disconnection scenarios, and deliver a production-ready project that boosts your apps 10x in performance.

How WebSocket skills are assessed

  • Advanced technical quizzes, practical coding exercises, real case studies with individual feedback.

Our method

How Learni guarantees the quality of your WebSocket training

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.
