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.
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.

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.
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.
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.
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.
