TypeScript 5 for developers | Udemy

TypeScript is one of the most loved languages of the moment. How can you learn it properly and go beyond basic examples?

Typescript has reinvented the way we code JavaScript, first of all by adding type safety, but also with many other great features like access modifiers, generics, interfaces, classes, decorators and many others.

Typescript combines the flexibility of modern JavaScript with the power of strongly typed languages like Java or C#, making it a great choice for your full stack app.

Welcome to my course, in which you will learn basic and advanced Typescript and NodeJs by practice. We will not waste much time on presentations or reading the documentation, which you can do yourself, no course needed. Instead we will focus on coding a real, full stack application.

Typescript features covered:

• Installation and and setup inside a npm project
• Basic TypeScript compiler options like sourceDir and Target
• Primitive types, build-in types, advanced types, utility types
• Any vs unknown vs never
• Objects, Interfaces and Classes
• Type aliases, type narrowing optional values, type intersection
• Enums and exhaustive enums in TypeScript
• Abstract classes and inheritance
• Generics and decorators – both old and new (version 2 and 3)
• Advanced types like conditional types, literal types, mapped types

The Advanced TypeScript environment:

• Understand how npm packages work by building and using your own npm package with TypeScript
• Run and analyze TypeScript code on both NodeJs and Browser
• Deeply understand how module bundlers like WebPack and EsBuild work

Practice sessions with NodeJs, Express and React:

• Build from scratch a CRUD application with Node, Express and TypeScript – Rest API
• Understand how Express routing works
• Understand how Express middleware works
• Use ZOD for data validation inside a Node Express app
• Deeply understand how module bundlers like WebPack and EsBuild work
• Build from scratch a UI app with React and TypeScript
• Recap for React state, props and hooks
• Understand how React components work and how to pass data between child/parent components
• Integrate the Express rest API with React

This course stands out with many advantages and highlights:

• Concise and with deep respect for your time: only learn what you need. Most of the instructor typing is cut, focusing on why we write a certain way the code.
• Unitary Typescript course theme – the same NodeJs application, so you don’t get bored and get a rewarding sense of completion
• Experienced and programming active instructor: a great teacher never looses touch with the industry. This is especially true for software development, where the industry is so dynamic. This helps the instructor stay up to date with the best coding guidelines and present you the challenging parts, not the “hello world”
• GitHub Code diffs – for each lecture – this way you can keep up and quickly get an overview of the lecture, in case you missed something
• Great visuals – dark background, big font, 1080p resolution
• Certificate of completion

The best way to learn is by exercise, so I’ll see you in class.

There will be code!
