Learning objectives

  • Implement fine-grained reactivity with signals, effects, and memos.
  • Build scalable global stores and asynchronous resources.
  • Optimize renders for 10x superior performance.
  • Integrate advanced routing and SSR with SolidStart.
  • Develop reusable and testable component patterns.
  • Manage complex state and advanced side effects.
  • Deploy secure production SolidJS applications.

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 SolidJS expertise, your apps suffer excessive re-renders, inflating CPU usage by 50% and latency by 40% according to Web Vitals benchmarks.

  • Lose 30% of mobile users frustrated by heavy frameworks like React, while agile competitors on SolidJS scale 10x without lag.

  • Risk exploding cloud costs (+200% on AWS), slow updates, and rapid obsolescence in 2024.

  • Invest now for native performance, fine-grained reactivity, and a sustainable competitive edge, avoiding these costly pitfalls that hinder your dev career.

Program

Module 1Fine-Grained Reactivity: signals, effects, memos in SolidJS (interactive exercises, reactive prototypes)

Dive into the heart of SolidJS, manipulate signals for granular reactivity, code effects and memos to avoid unnecessary re-renders, complete exercises on dynamic dashboards, analyze real mobile optimization cases, produce an ultra-smooth prototype that outperforms React in performance.

Module 2Advanced State Management: stores, resources, SolidJS contexts (real cases, scalable deliverables)

Master global stores and fetch resources for data-driven apps, integrate nested contexts without boilerplate, develop exercises on complex e-commerce, simulate real asynchronous flows, generate reusable shared state components, boost your code to expert scalability.

Module 3Optimization and Patterns: profiling, lazy loading in SolidJS (benchmarks, refactorings)

Push performance to the max with built-in profiling and lazy loading, refactor legacy apps to SolidJS, conduct React vs Solid benchmarks, code advanced hooks patterns, test on high-load cases, deliver an optimized module reducing latency by 70%, ready for production.

Module 4Pro Ecosystem: SolidStart, SSR, SolidJS Deployment (final project, CI/CD)

Integrate SolidStart for native routing and SSR, set up Vercel/Netlify deployments, build a full-stack capstone project, automate CI/CD with end-to-end tests, manage advanced authentication, deploy a live expert app, leave with a concrete portfolio and production-ready skills.

Evaluation method

  • Daily interactive quizzes, final evaluated project, Qualiopi certification

Learning method

  • 70% hands-on practice, 30% applied theory, real business cases

Methods, materials and delivery

The SolidJS Expert Training - Ultra-High-Performance Reactive 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 SolidJS Expert Training - Ultra-High-Performance Reactive 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 SolidJS Expert Training - Ultra-High-Performance Reactive 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.

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.
