Learning objectives

Master reactive signals for fine-grained and performant reactivity
Build reusable and optimized SolidJS components
Implement dynamic routing and advanced state management
Optimize performance with directives and stores
Develop and deploy a complete SolidJS application
Integrate SolidJS into existing projects with external APIs

Program

Module 1SolidJS Fundamentals: Signals and Reactivity (Vite, JSX, practical exercises)

Dive into SolidJS reactive primitives, set up your environment with Vite, create your first signals and effects for granular reactivity, complete exercises on local state management, build an advanced interactive counter, test performance without Virtual DOM, leave with a functional prototype that outperforms React in smoothness.

Module 2Advanced Components: Props, Events, Lifecycle (SolidJS Tools, Real-World Cases)

Deepen components with reactive props and events, implement lifecycle via onMount and onCleanup, develop a collaborative todo-list with persistent storage, integrate real-time validated forms, analyze concrete e-commerce app cases, produce modular components ready for integration, experience the power of a lightweight framework that boosts your productivity.

Module 3Routing and Global State: Solid Router, Stores (Advanced Methods, APIs)

Master Solid Router for smooth navigation without re-renders, create global stores for shared state, connect to REST APIs with reactive fetch, simulate a multi-page dashboard app with authentication, handle errors and lazy loading, build a scalable intermediate project, discover how SolidJS reduces bundles by 40% compared to competitors.

Module 4Optimizations and Deployment: Directives, SSR, Final Project (Prod Tools, Deliverables)

Optimize with directives like createResource and Suspense, implement SSR for SEO, profile performance with Solid DevTools, deploy on Vercel or Netlify, finalize a capstone project like a dynamic blog, receive personalized feedback, leave certified with a concrete portfolio, ready to transform your apps into benchmarks of speed and reactivity.

Evaluation method

Daily interactive quizzes, graded final project, skills self-assessment before/after.

Learning method

70% hands-on with real exercises, 30% applied theory, individual mentoring.

Methods, materials and delivery

The Training SolidJS - Build Ultra-Performant Reactive Apps program is delivered onsite or remote (blended-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 SolidJS - Build Ultra-Performant 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.

Skills assessment methods

Assessment of skills acquired during the Training SolidJS - Build Ultra-Performant 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 built for corporate L&D budgets and delivered onsite or remotely.

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.

Frequently asked questions

Which tools are used in SolidJS training?+

Hands-on work runs on vite, JSX, practical exercises, solidJS Tools, real-World Cases and advanced Methods. Those tools come from the SolidJS program itself, delivered on site over 4 days, so participants practise on the stack they will use at work.

What can participants do after SolidJS training?+

They can master reactive signals for fine-grained and performant reactivity, build reusable and optimized SolidJS components and implement dynamic routing and advanced state management. Those are the stated objectives of the SolidJS program at Intermediate level, checked by the end-of-session assessment.

What does the SolidJS program cover, day by day?+

Day 1: SolidJS Fundamentals: Signals and Reactivity (Vite, JSX, practical exercises). Day 2: Advanced Components: Props, Events, Lifecycle (SolidJS Tools, Real-World Cases). Day 3: Routing and Global State: Solid Router, Stores (Advanced Methods, APIs). Day 4: Optimizations and Deployment: Directives, SSR, Final Project (Prod Tools, Deliverables). The SolidJS program runs over 4 days, delivered on site.

How is SolidJS training assessed?+

Assessment relies on daily interactive quizzes, graded final project, skills self-assessment before/after. Learni issues a completion certificate together with the individual assessment report at the end of the SolidJS program, which an L&D team can file as evidence.

How much does SolidJS training cost per participant?+

SolidJS training is priced on quote. The amount depends on headcount, format and how far the syllabus is tailored to your team.
