Advanced TypeScript

• Understanding of Typescript fundamentals
• Understanding of Node.js

Audience

• Developers

TypeScript is an open source language for building enterprise Javascript applications. It is a strict superset of JavaScript that compiles to plain Javascript and brings static typing and object-oriented development to the language.

This instructor-led, live training (online or onsite) is aimed at developers who wish to use TypeScript's advanced features to create and build JavaScript applications.

By the end of this training, participants will be able to:

• Set up the necessary development environment to start developing TypeScript and Node.js applications.
• Take advantage of Typescript's advanced capabilities to write clean, expressive code with fewer errors.
• Configure and use Webpack with TypeScript to build complex front-end UIs.
• Use custom data types (Union, Intersection, Tuple Types, etc.) to extend existing generic types.
• Implement asynchronous code patterns and APIs for error handling and validating responses.
• Deploy TypeScript and Node.js applications to production environments (AWS EC2, Heroku, etc.).

Format of the Course

• Interactive lecture and discussion.
• Lots of exercises and practice.
• Hands-on implementation in a live-lab environment.
