Learning objectives

  • Master advanced stores and Svelte context for scalable professional applications
  • Develop skills in SvelteKit to deploy high-performance full-stack sites in enterprise environments
  • Implement runtime and SSR optimizations to boost Core Web Vitals metrics
  • Design reusable components with runes and slots for effective certification training
  • Optimize Svelte performance in critical production environments
  • Integrate Svelte into existing stacks for rapid skill advancement
  • Audit and refactor legacy apps to Svelte for enhanced technical compliance

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 1Advanced Svelte: stores, context, and reusable components (runes, slots, transitions)

Discover the deep mechanisms of Svelte stores for decentralized state management, implement the context API with practical exercises on real business cases, create composable components via advanced runes and slots, test smooth animations with custom transitions, produce modular deliverables ready for production, while analyzing live performance metrics using tools like Svelte REPL.

Module 2Expert SvelteKit: routing, SSR, and API routes (dynamic layouts, load functions)

Dive into SvelteKit to architect full-stack apps, configure advanced routing with parameterized segments and nested layouts, implement SSR and hydration for perfect Lighthouse scores, develop secure API routes with middleware hooks, perform exercises on authentication and error handling, generate automated sitemaps, and deploy to Vercel or Netlify with integrated CI/CD.

Module 3Svelte Optimization and Audit: performance, security, and refactoring (profiling, bundles)

Audit existing Svelte apps with profiling tools like Chrome DevTools, optimize bundles via tree-shaking and advanced code-splitting, integrate security measures like CSP and sanitization, refactor legacy code to modern Svelte patterns, simulate high loads to test resilience, produce a complete audit report with recommendations, and validate gains through real benchmarks.

Evaluation method

  • Interactive technical quizzes at the end of each day
  • Full-stack capstone project with SvelteKit
  • Personal audit of an existing app and presentation

Learning method

  • 70% hands-on practice with remote exercises
  • Case studies of leading companies using Svelte
  • Unlimited access to a shared collaborative workspace
  • Post-training resources for self-improvement

Methods, materials and delivery

The Training Svelte - Mastering Ultra-Performant Web Apps 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 Svelte - Mastering Ultra-Performant Web Apps 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 Svelte - Mastering Ultra-Performant Web Apps 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.
