The Learni story
Founded by passionate learning and innovation experts, Learni's mission is to make professional training accessible to everyone, anywhere in the world. Our team operates in major hubs — London, New York, Boston — and internationally, to support talents and organizations in upskilling.
Don't let this gap widen
Why this program matters
Without this upskilling, your team accumulates a technological gap that translates directly into productivity loss.
Organizations that don't train their talents on key topics see their competitiveness drop.
Every quarter without training is a gap widening with competitors who invest.
The cost of inaction quickly exceeds that of well-targeted training.
Program
Module 1MSW Fundamentals: Installation and Basic Handlers (Jest tools, initial configurations, first mocks)
Discover the quick installation of MSW in a React or vanilla JS project, configure workers to intercept HTTP requests, create your first REST and GraphQL handlers with static or dynamic responses, perform practical exercises on simulated e-commerce APIs, produce reliable unit tests without depending on real backends, integrate MSW with Jest to validate complete user flows, and end with a deliverable: a functional mocked project.
Module 2Advanced MSW: Complex Scenarios and Persistence (dynamic methods, shared state, debugging tools)
Dive into conditional handlers to simulate 404 errors, network latencies, and authentications, manage persistent state between requests with MSW stores, debug effectively via the browser panel, apply to concrete cases like SaaS apps with mocked payments, chain exercises on paginated and real-time APIs, integrate with frameworks like Next.js or Vue, and generate a deliverable: suite of end-to-end mocked tests with performance metrics.
Module 3MSW 2026 Integration: CI/CD and Best Practices (GitHub Actions pipelines, enterprise optimizations, deployments)
Master MSW integration into CI/CD pipelines with GitHub Actions and Vercel, configure presets for micro-frontends, optimize for multi-team environments, explore MSW 2026 novelties like advanced WebSocket mocks, apply to hybrid RPA projects with UiPath, complete a final challenge on a fully mocked analytics dashboard, share experiences, and obtain a deliverable: production-ready Git repository with full documentation.

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.
