Why this program matters

Without expert mastery of Redux Toolkit, your React applications accumulate unpredictable state bugs, leading to 25% losses in user retention according to Google studies.
Performance drops 40% on complex apps, driving 30% cart abandonments in e-commerce and tripling maintenance costs.
Senior developers face stagnant careers against scalable competitors while companies expose themselves to critical downtimes and annual revenue losses estimated at 150k€.
Act now to secure scalability and tech leadership.

Learning objectives

Master Redux Toolkit for developing performant stores in enterprise environments.
Design advanced slices and RTK Query for robust APIs.
Optimize professional state management with Immer and TypeScript.
Implement expert patterns such as Reselect and custom middleware.
Deploy scalable, certified solutions for complex React applications.
Develop skills in advanced debugging and testing Redux Toolkit.

Program

Module 1Redux Toolkit Fundamentals: configureStore, slices, and Immer (basic tools, project setup)

Discover the expert basics of Redux Toolkit via configureStore to initialize an optimized store, create your first slices with createSlice integrating reducers and automated actions thanks to Immer. Apply practical exercises on a real React project, migrate a classic Redux store to Toolkit, analyze immediate performance gains, produce a modular production-ready store with integrated logging and hot-reload.

Module 2Advanced State Management in Redux Toolkit: RTK Query and caching (API calls, mutations, queries)

Dive into RTK Query to manage API calls declaratively, configure endpoints with createApi, implement automated queries, mutations, and optimistic updates. Test on concrete e-commerce app cases, optimize caching with tags and invalidations, integrate infinite pagination, generate TypeScript hooks, measure 70% boilerplate reduction and improve user responsiveness via interactive remote exercises.

Module 3Expert Redux Toolkit Patterns: selectors, middleware, and normalization (Reselect, normalizr)

Master Reselect for performant memoized selectors, integrate normalizr via RTK for normalized data, create custom middleware for advanced logging and local persistence. Apply to a complex dashboard with relational data, debug with Redux DevTools, test scalability on 100k+ states, produce reusable patterns, analyze impacts on FPS and bundle size during practical group challenges.

Module 4Production and Testing Redux Toolkit: deployment, CI/CD, and best practices (Jest, perf audits)

Finalize with unit testing via Redux Toolkit utilities and Jest, implement performance audits with React Profiler, configure CI/CD for scalable stores, apply security best practices like sanitization. Develop a complete capstone project, migrate a legacy app, generate certified deliverables with expert code review, anticipate future evolutions like Redux 5, ensure immediate professional expertise in the enterprise.

Evaluation method

Skills assessment methods

Assessment of skills acquired during the Training Redux Toolkit - Optimizing Expert State Management in React program is performed through:

During training: case studies, hands-on labs and professional scenarios
End of training: self-assessment questionnaire and skills evaluation by the trainer
After training: completion certificate detailing acquired skills

Program accessibility

Learni is committed to making its programs accessible. All our programs are accessible to people with disabilities. Our teams are available to adapt the pedagogical methods to your specific needs. Please contact us for any adjustment request.

Enrollment terms and lead times

Registration is possible up to 48 business hours before the start of training. All our programs are built for corporate L&D budgets and delivered onsite or remotely.

The Learni story

Founded by engineers and learning experts, Learni's mission is to make high-impact tech training accessible to teams everywhere. We work remotely with organizations across the US and Canada, in your time zone, to help teams upskill fast.

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 Redux Toolkit training?+

Hands-on work runs on basic tools, project setup, API calls, mutations, queries and reselect. Those tools come from the Redux Toolkit program itself, delivered on site over 4 days, so participants practise on the stack they will use at work.

What can participants do after Redux Toolkit training?+

They can master Redux Toolkit for developing performant stores in enterprise environments, design advanced slices and RTK Query for robust APIs and optimize professional state management with Immer and TypeScript. Those are the stated objectives of the Redux Toolkit program at Expert level, checked by the end-of-session assessment.

What does the Redux Toolkit program cover, day by day?+

Day 1: Redux Toolkit Fundamentals: configureStore, slices, and Immer (basic tools, project setup). Day 2: Advanced State Management in Redux Toolkit: RTK Query and caching (API calls, mutations, queries). Day 3: Expert Redux Toolkit Patterns: selectors, middleware, and normalization (Reselect, normalizr). Day 4: Production and Testing Redux Toolkit: deployment, CI/CD, and best practices (Jest, perf audits). The Redux Toolkit program runs over 4 days, delivered on site.

How is Redux Toolkit training assessed?+

Assessment relies on advanced technical quiz on slices and RTK Query (80% success required), case study: refactoring a legacy store to Redux Toolkit and final project: scalable React application with complete testing. Learni issues a completion certificate together with the individual assessment report at the end of the Redux Toolkit program, which an L&D team can file as evidence.

How much does Redux Toolkit training cost per participant?+

Redux Toolkit training is priced on quote. The amount depends on headcount, format and how far the syllabus is tailored to your team. A detailed quote is sent within one business day, and team pricing covers the whole group from the second participant.

Who pays for Redux Toolkit training?+

Most US teams pay directly through their company L&D or training budget. Learni invoices in US dollars and accepts bank transfer (ACH/wire) or card, with volume pricing for teams. A purchase order is welcome.

What do participants need to know before Redux Toolkit training?+

Advanced proficiency in React (custom hooks, Context API), experience with vanilla Redux (actions, reducers, middleware), knowledge of TypeScript, web performance, and modular architectures.

Is a certificate issued after Redux Toolkit training?+

Yes. A Learni completion certificate is issued, along with the individual evaluation report. Learni is a certified training provider and prepares for third-party certifications, but does not award them itself.
