Why this program matters

Without this SolidJS training, your React apps risk 3x more unnecessary re-renders, bloating bundles by 40% and slowing mobile users (25% higher cart abandonment).
Lose contracts to competitors 2x faster, with unattainable 60fps UI performance.
70% of frontend devs stagnate on obsolete frameworks, missing 15k€/year in boosted salaries.
Avoid sleepless nights on state bugs, train for scalable apps starting tomorrow.

Learning objectives

Master the fundamentals of SolidJS and its fine-grained reactive paradigm.
Create reusable components with JSX and props.
Manage local and global state via Signals and Stores.
Implement SPA routing and navigation.
Integrate APIs and manage side effects.
Optimize and deploy a complete SolidJS application.
Compare SolidJS to React for informed technical choices.

Program

Module 1Introduction to SolidJS: setup and first reactive components (Vite, JSX, dev tools).

Dive into SolidJS by installing the environment with Vite, create your first project, build basic components with reactive JSX, test fine-grained updates live, complete interactive exercises on reactivity, produce a simple portfolio at the end of the day to visualize immediate gains.

Module 2Advanced components: props, events, conditionals (composition methods, hooks).

Build hierarchical components by passing dynamic props, handle keyboard and mouse events with reactive handlers, implement conditional lists and loops, practice on real cases like a todo-list, generate reusable components, feel the fluidity that makes you want to code faster.

Module 3State management: Signals, Stores, derivation (fine-grained reactivity without boilerplate).

Discover Signals for ultra-reactive state, create Stores for global state, derive computed values automatically, apply to complex forms with real-time validation, practice on simulated multi-user apps, obtain performant deliverables that outperform competitors in speed.

Module 4Routing and APIs: SPA navigation, asynchronous fetch (Solid Router, Suspense).

Install Solid Router for dynamic routes, integrate API calls with fetch and Suspense for lazy-loading, manage errors and loading states, develop a complete e-commerce app with persistent cart, test in real conditions, produce a deployable project that impresses with its reactivity.

Module 5Optimization and deployment: performance, build, hosting (Vitest, Vercel/Netlify).

Profile your apps for optimal performance, write unit tests with Vitest, configure production build, deploy on Vercel or Netlify in one click, optimize for mobile and SEO, finalize a personal capstone project, leave with a pro portfolio ready to boost your career.

Evaluation method

Continuous assessments through practical exercises, daily interactive quizzes, final graded project with personalized feedback.

Learning method

70% hands-on, 30% theory, real-world exercises, immediate feedback, unlimited video replays.

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.

FAQ

Frequently asked questions

Which tools are used in SolidJS training?+

Hands-on work runs on vite, JSX, dev tools, composition methods, hooks and solid Router. Those tools come from the SolidJS program itself, delivered on site over 5 days, so participants practise on the stack they will use at work.

What can participants do after SolidJS training?+

They can master the fundamentals of SolidJS and its fine-grained reactive paradigm, create reusable components with JSX and props and manage local and global state via Signals and Stores. Those are the stated objectives of the SolidJS program at Beginner level, checked by the end-of-session assessment.

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

Day 1: Introduction to SolidJS: setup and first reactive components (Vite, JSX, dev tools). Day 2: Advanced components: props, events, conditionals (composition methods, hooks). Day 3: State management: Signals, Stores, derivation (fine-grained reactivity without boilerplate). Day 4: Routing and APIs: SPA navigation, asynchronous fetch (Solid Router, Suspense).
