Why this program matters

  • Without this advanced TypeScript training, your apps risk 40% more runtime bugs due to loose types, doubling debug time (up to 20h/week lost).

  • Teams lose scalability: JS to TS migrations fail 60% of the time, hindering enterprise projects.

  • Recruiters discard 70% of CVs without advanced types expertise.

  • Save 500h/year in production, avoid costly downtimes (15k€/incident), go from junior to expert in 4 days to boost salaries by 20%.

TypeScript Advanced training objectives

  • Master advanced types like unions, intersections, and conditionals.
  • Implement powerful generics for reusable libraries.
  • Develop decorators and metaprogrammation to optimize code.
  • Integrate TypeScript into Angular, React, or Node.js with smooth migrations.
  • Manage typed errors and performance for scalable apps.
  • Build modules and namespaces for enterprise architectures.
  • Produce typed deliverables ready for production.

TypeScript Advanced curriculum: 4 modules over 4 days

Module 1 : Advanced Types: Unions, Intersections, Mapped Types (VS Code, Node.js)

Dive into complex types by practicing on VS Code and Node.js, build conditional unions to validate API data, manipulate mapped types through interactive exercises on real datasets, test intersections for nested objects, produce a first robust typed deliverable that compiles without errors, gain fluency to code faster and bug-free.

Module 2 : Generics and Utilities: Powerful Templates (TypeScript Playground)

Explore advanced generics in TypeScript Playground, create templated functions for arrays and objects, apply generic constraints to concrete cases like REST APIs, optimize with utility types like Partial and Pick, complete collaborative pair exercises, generate a reusable generic module, transform your habits to develop scalable libs in a snap.

Module 3 : Decorators and Modules: Metaprogramming (Webpack, Angular CLI)

Master decorators by integrating Webpack and Angular CLI, code decorators for logging and automatic validation, structure namespaces and modules for large projects, test on a real e-commerce case with typed authentication, collaborate live to debug, produce an optimized typed bundle, discover tips that boost your productivity by 40% starting tomorrow.

Module 4 : Advanced Projects and Best Practices: Framework Integration (React, Node.js)

Finalize with a complete project in React or Node.js, migrate a JS codebase to advanced TypeScript, integrate everything via typed hooks and Express routers, analyze performance with tools like TSC and Jest, review best practices in a group, deliver a production-ready GitHub repo, leave with a concrete portfolio that impresses recruiters and clients.

Our method

How Learni guarantees the quality of your TypeScript Advanced training

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.
