Don't let this gap widen
Why this program matters
Without SolidJS, your React apps overload the DOM, multiplying re-renders by 5 and bloating bundles by 40%, doubling load times and causing 25% of mobile users to abandon.
Competitors are already adopting this 2x faster technology, leaving you with mediocre performance, +20% dev costs, and an obsolete stack.
Lose contracts due to slow UIs, miss tight deadlines, or train now to boost your apps to 60 FPS, reduce bugs by 50%, and dominate the reactive frontend market.
Program
Module 1SolidJS Fundamentals: Reactive Signals and JSX (SolidJS, Vite, basic exercises)
Dive into signals for granular reactivity without a virtual DOM, set up your project with Vite, code your first reactive components through practical exercises on dynamic counters and filtered lists, test ultra-fast live updates, and leave with a ready-to-use template that boosts productivity from day 1.
Module 2Advanced Components and Props: Reusable Patterns (SolidJS, hook patterns, e-commerce cases)
Build conditional and iterative components with reactive props, apply patterns like children props and portals, complete a hands-on exercise on an interactive product catalog, integrate CSS-in-JS styles, visualize performance gains, and validate your skills with a deliverable mini-project that will impress your peers.
Module 3Routing and State: Solid Router + Stores (SolidJS, lazy routing, global management)
Set up a performant router with lazy loading for fluid SPA apps, implement Stores for shared state without boilerplate, code a dashboard app with simulated authentication and nested navigation, manage API queries via reactive fetch, test seamless transitions, and produce a production-ready functional prototype.
Module 4Optimizations and Deployment: Performance + CI/CD (SolidJS, profiling, Vercel/Netlify)
Profile your apps to track memory leaks, apply memos and lazy loading to divide render times by 3, integrate Suspense for streaming, deploy on Vercel with automated CI/CD, finalize a personal capstone project on a collaborative todo app, receive expert feedback and certification, and launch confidently into professional SolidJS.
Evaluation method
- Daily interactive quizzes, graded practical exercises, final project assessed by experts, Qualiopi certification.
Learning method
- 70% hands-on with real-world cases, 30% targeted theory, individual coaching in small groups.

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.
