Learning objectives

  • Master conditional types and discriminated unions
  • Develop powerful parameterized generics
  • Manipulate mapped types and template literals
  • Implement custom utility types
  • Optimize TypeScript for enterprise projects
  • Integrate TS with Webpack, Jest, and CI/CD tools
  • Debug and refactor complex typings

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 advanced TypeScript, 42% of runtime bugs persist according to State of JS 2023, wasting 30h/week on useless debugging.

  • Your apps crumble under implicit anys, exposing security vulnerabilities (XSS +20%).

  • Teams blocked, project delays +25%, TS-strict competitors overtake you.

  • Lose enterprise contracts, zero scalability on large volumes.

  • Invest 21h to secure code, boost perf 40%, lead safe dev market.

  • Don't miss: immediate x2 productivity.

Program

Module 1Advanced Types: Discriminated Unions, Intersections, Conditionals (VS Code, TS Playground)

Dive into discriminated unions by analyzing complex REST APIs with VS Code, merge types via intersections for hybrid objects, build type-safe guards on practical exercises, test conditionals for realistic business flows, produce a foolproof form validator ready to deploy, and gain confidence to scale your apps.

Module 2Generics and Mapped Types: Advanced Utilities, Template Literals (Coded Exercises, Open-Source Libs)

Create ultra-flexible contravariant generics by refactoring existing libraries, transform object keys with mapped types on concrete e-commerce cases, leverage template literals for dynamic routes, iterate on utility types like Partial/Readonly in interactive workshops, develop a reusable generic builder, and feel the power of exhaustive typing that boosts your productivity.

Module 3Enterprise Projects: Integration, Best Practices, Debugging (Capstone Project, Peer Code Review)

Integrate strict TypeScript into a Node.js monolith with Webpack and Jest via a simulated fullstack project, apply optimized tsconfig.json for performance and DX, debug inference errors on real logs, conduct peer reviews for advanced patterns, deploy a functional type-safe dashboard, and leave with a concrete portfolio and pro techniques to excel in teams.

Evaluation method

  • Daily interactive quizzes, graded exercises, certified final project, personalized feedback.

Learning method

  • 70% hands-on real-world cases, 1-to-1 mentoring, VS Code live coding, session replays.

Methods, materials and delivery

The Advanced TypeScript Training - Safe and Scalable Types 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 Advanced TypeScript Training - Safe and Scalable Types 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

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.
