This course also includes the Ebook: Typescript Jumpstart — Fast-track to Typescript Proficiency, For Experienced Developers.
You are going to learn Typescript 2, its ES6 Features and its advanced type system in depth. You will then use Typescript to build a Node REST API in Express and query a SQL database in Typescript using the Sequelize ORM. You will build a small Angular Typescript Client using the Angular CLI and you will query the REST API using the Angular HTTP Module.
The main goal of the course is that you learn not only the Typescript language features, but that you also learn how to use them in practice to build concrete programs. We will cover the benefits of type safety and how it helps us to write better programs.
We will do a complete introduction to Typescript 2 and to its type system. We will then immediately apply these new concepts to a practical example: we will build a REST API in Node using Express and Typescript, and then we will query a Postgresql relational database using the Sequelize ORM.
We will learn how to use Typescript with third party Javascript libraries and still write type safe programs. The goal is to give a theoretical introduction to the language, but then immediately drive home those concepts by applying them to everyday tasks that we will all do in our daily lives as software developers.
The course structure is simple: we will setup the Webstorm IDE step by step, and start introducing Typescript simply as a better Javascript, showing main of the ES6 features that we can use already today.
We will learn best practices for building our backend in a functional way and on how to build APIs with Express. We will discuss aspects like API security and error handling. Sequelize is our ORM of choice we will show how to query SQL database tables and show how to compose our program into reusable small functions and use them to compose promise chains to handle API requests.
