Why this program matters

  • Without mastery of Redux Toolkit 2026, 70% of advanced React apps suffer from unnecessary re-renders, resulting in load times exceeding 3 seconds and a 53% loss of mobile users according to Google benchmarks.

  • Companies lose up to 25% of dev productivity due to unpredictable state bugs, impacting UX KPIs like conversion rates.

  • Careers stagnate: front-end developers without these advanced skills struggle to advance to lead or architect roles, with a 20k€ annual salary gap.

  • Invest now to secure lasting performance and professional advancement.

Learning objectives

  • Master Redux Toolkit to develop professional skills in scalable state management
  • Implement RTK Query to optimize API calls in enterprise-certified applications
  • Design modular and reusable slices for complex UX/UI projects
  • Optimize React performance with Redux Toolkit in real production environments
  • Deploy advanced patterns for robust and maintainable architecture

Program

Module 1Redux Toolkit 2026 Foundations: Advanced Configuration and Slices (createSlice, configureStore)

Dive into the new features of Redux Toolkit 2026 with quick npm installation, create slices for local state management, integrate configureStore for boilerplate-free setup. Practice on real UX cases like a user dashboard, debug with Redux DevTools, generate automated actions and reducers, test immutable mutations to avoid common enterprise bugs. Deliverable: Configured store and functional slice for a Figma-imported prototype.

Module 2RTK Query: Advanced API Management (createApi, endpoints, caching)

Explore RTK Query for optimized queries and mutations, define endpoints with tags for smart invalidation, automatic API data caching. Apply to UX flows like real-time Figma design synchronization, manage optimistic updates, integrate pagination and polling. Practice on real REST/GraphQL APIs, analyze network performance, produce custom hooks. Deliverable: Complete API module with persistent cache for web mobile app.

Module 3React + Redux Toolkit 2026 Integration: Hooks and Middleware (useSelector, useDispatch)

Integrate Redux Toolkit with React using useSelector and useDispatch for optimal reactivity, combine with React Router for complex SPA apps. Develop native saga-like middleware, manage asynchronous side effects for smooth Figma-sourced UI interactions. Practice lazy loading of slices, refactor an existing project, optimize re-renders. Deliverable: Connected React component with managed global state and animated UX transitions.

Module 4Performance and Advanced Redux Toolkit Patterns: Normalizr, Advanced Selectors

Optimize with Reselect for memoized selectors, structure normalized entities for large UX analytics datasets. Implement patterns like entity adapters, manage SSR hydration, integrate Immer for secure mutations. Test on enterprise cases with 10k+ items, profile with React Profiler, apply to Figma-prototyped dashboards. Deliverable: High-performance architecture with before/after optimization benchmarks.

Module 5Real Projects and Redux Toolkit 2026 Best Practices: Deployment, Testing, Security

Build a capstone project integrating all tools, from Figma to Vercel/Netlify deployment, with Jest/RTL tests for slices and queries. Adopt 2026 best practices like code splitting, CSRF security in RTK Query, monitoring with Sentry. Share in pairs, peer code review, prepare for enterprise production. Deliverable: Fully deployed application, portfolio-ready, with performance report and skills certification.

Evaluation method

  • Daily technical quizzes on Redux Toolkit concepts
  • Individualized final project with mentor feedback
  • Group enterprise case study for skills validation

Learning method

  • Hands-on practical exercises 70% of the time
  • Real UX/UI app case studies
  • Personalized mentoring in small groups of max 10
  • Collaborative projects inspired by Figma for rapid prototyping

Methods, materials and delivery

The Training Redux Toolkit 2026 - Optimizing Advanced React State Management 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 Redux Toolkit 2026 - Optimizing Advanced React State Management 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

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.
