Who it’s for

Developers who use TypeScript daily and want to go beyond the basics
Teams maintaining shared libraries or complex domain models

Afterwards your team can

Model domain rules in the type system instead of in runtime checks
Write generic, reusable utilities with precise types
Read and extend advanced types in third-party libraries

Prerequisites

Practical TypeScript experience
Comfortable with interfaces, unions and generics basics

Level up your TypeScript skills with this TypeScript Advanced Course. Get a deeper understanding of how TypeScript works and how you can use advanced concepts and types to enhance your software projects. Writing more robust and expressive code while applying best practices will improve your overall developer experience, make you and your team more efficient, and reduce maintenance effort.

Agenda

The order and the depth of each block are adapted to your team – topics you already master are skipped, your questions get the time instead.

Basics
A small summary of the basic abilities and limitations of TypeScript.
Type System
Learn about type systems in different languages and how TypeScript’s type system works.
Advanced Types
Create more flexible as well as expressive types with Union and Intersection Types.
Utility Types
Leverage TypeScript’s Utility Types, which cover some of the most common type transformations.
Never
Gain knowledge about the concept of the Never Type and how you can use this type to tell TypeScript about situations that should never happen.
Generics
Master generics with a deep dive into generic constraints, inferring types from other types, as well as type recursion.
Literals & Template Literals
Learn how to use more specific types than just string and number. Get a better understanding of how to combine these types and specifically tell TypeScript to narrow down objects and arrays to their most specific type on its own.
Mapped Types
Create types based on other types to avoid redundancy and enforce changes across connected types.
Type Guards
Explore the possibilities of how to securely recognize and narrow down specific types.
Branded Types
Explore a more advanced concept on how to create types for more complex patterns like emails or social security numbers.

Prerequisite for this Course

A prerequisite for this course is that you have already worked with TypeScript to some extent. A basic understanding of the language and its concepts is necessary to follow the advanced topics.
