Learning objectives

  • Master conditional types and mapped types for advanced professional TypeScript skills.
  • Develop powerful generics tailored to enterprise needs in certified training.
  • Optimize refactoring of legacy JavaScript code to scalable TypeScript.
  • Implement custom utilities to boost team productivity.
  • Integrate TypeScript with Next.js for performant and maintainable web applications.
  • Acquire certified skills in static typing for critical professional projects.

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.

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 1Advanced Types: Unions, Intersections, and Type Guards (refactoring exercises, enterprise use cases)

Discover discriminated unions and intersections to model complex data, apply type guards for safe runtime, refactor existing JavaScript code live with VS Code, analyze common errors via the IDE, produce reusable typed functions, test on real enterprise datasets, and validate your skills through a timed practical exercise of 7 hours over 4 remote days.

Module 2Generics and Mapped Types: Advanced TypeScript Utilities (creating helpers, reusable patterns)

Dive into conditional and inferred generics, build mapped types to transform objects dynamically, develop custom utility types like PartialDeep or DeepReadonly, integrate them into a collaborative project via Git, solve inferno typing challenges, apply to complex REST APIs, generate testable deliverables with Jest, and consolidate with a 7-hour interactive remote workshop.

Module 3Modules and Namespaces: Modular TypeScript Architecture (Next.js integration, esbuild bundling)

Structure applications with declaration merging and namespaces, configure tsconfig.json for enterprise monorepos, integrate TypeScript into Next.js for typed SSR, migrate a React project to full TS, optimize builds with esbuild and SWC, manage typed dependencies via DefinitelyTyped, deploy a prototype on Vercel, test performance, and end with advanced debugging in a 7-hour live remote session.

Module 4Best Practices and Performance: Enterprise TypeScript Migration (benchmarks, CI/CD GitHub Actions)

Adopt patterns like branded types and nominal typing for enhanced security, measure post-migration performance gains, implement strict mode in production, automate TS checks in CI/CD pipelines, analyze metrics with TypeScript Analyzer, migrate a complete legacy codebase, produce an ROI report, share solutions in group, and conclude with expert Q&A over final 7 hours in certified remote format.

Evaluation method

  • Daily interactive quizzes on advanced types and generics (80% success required).
  • Final project: migration of a Next.js app to strict TypeScript with Git deliverables.
  • Qualiopi certificate issued post-evaluation, validating professional skills.

Learning method

  • Practical projects on real business cases for immediate skill anchoring.
  • Hands-on exercises in pairs with real-time trainer feedback.
  • Replay videos and open-source resources for post-training review.
  • Advanced debugging simulations on complex TypeScript/Next.js codebases.

Methods, materials and delivery

The Training TypeScript - Master Advanced Typing for Scalable Apps 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 TypeScript - Master Advanced Typing for Scalable Apps 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
  • Post-training access to materials and educational resources

For intra-company training on a site outside Learni, the client commits to providing all required teaching materials (computers, internet, etc.) for the smooth delivery of the program in line with the prerequisites in the communicated program.

Skills assessment methods

Assessment of skills acquired during the Training TypeScript - Master Advanced Typing for Scalable Apps 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.

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.
