Why this program matters

Without SolidJS, your React or Vue apps risk unnecessary re-renders, inflating bundles by 30% and slowing mobile users by 2 seconds per interaction, according to Web Vitals benchmarks.
Lose 20% productivity in endless debugging, miss high-salary frontend jobs (average +15k€/year), and let competitors adopt this fine-grained tech that boosts Core Web Vitals by 40%.
Avoid costly rewrites: train for fluid UIs tomorrow.

Learning objectives

Discover the fundamentals of SolidJS and its ecosystem
Master fine-grained reactivity with signals
Create reusable and performant components
Manage local state and props effectively
Implement effects and stores for dynamic apps
Build and deploy a complete application

Program

Module 1SolidJS Fundamentals: Installation, JSX, and First Components (Vite, SolidJS CLI)

Install SolidJS via Vite, create your first project, dive into the unique JSX syntax, build simple components with props, complete interactive exercises on conditional renders and lists, generate a basic portfolio by the end of the day, while comparing with React to see immediate performance gains.

Module 2Fine-Grained Reactivity: Signals, State, and Effects (createSignal, createEffect)

Explore signals for granular reactivity, manage local state with reactive stores, implement effects for automatic updates, practice on concrete cases like an advanced counter or dynamic form, test updates without superfluous re-renders, produce an interactive dashboard that motivates action.

Module 3Advanced Applications: Routing, Optimization, and Deployment (Solid Router, SolidStart)

Integrate routing with Solid Router, optimize performance via memos and lazy loading, develop a complete e-commerce app in a team, deploy on Vercel or Netlify, analyze speed metrics, leave with a portfolio project ready to impress recruiters and clients.

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.
