Hands-On course, build frontend application with ReactJS and Typescript following by TDD

What you will learn

Build web applications with ReactJS using Hooks, Typescript, Redux

Create components library with the Storybook and CSS-IN-JS

Dive deeply into configurations of application with Webpack + Babel

Learn about TDD, TLD and apply this knowledge using Jest, React-Testing-Library and Stryker-Mutator


React is the most popular library for building frontend web applications. Step-by-step by diving into all the basics, I’ll introduce you to advanced concepts as well.

We’ll build the minesweeper application from scratch:

  • setup of the development environment

  • configuration of the ReactJS app

  • basic algorithms of Minesweeper

Step-by-step we’ll build the minesweeper game. During the course, we’ll cover the most important topics.

First will be a configuration of the ReactJSΒ application with Typescript and using build tools Webpack+Babel.

Second there’re presented TDD or TLD approaches that I’ll try to practice with you during the coding sessions. Probably you don’t have enough experience with the tests, but it’s ok, there’s still a good way to learn it from the course. When you work with code and cover it by test cases, it provides you with garantees that your code works as you expected. This is the purpose and benifit of the tests.

Also, I’ll try to cover basic Typescript concepts and show you a way to improve these skills. During the coding sessions, we’ll cover advanced Javascript techniques to make sense of commonly used JS features.

Storybook is the most popular way to build the components library. From our side it’s the most basic part of the course. We’ll install and configure Storybook, which will provides us with a full components spec. This approach is called Components Driven Development.

We’ll introduce you to React-Hooks – it’s the basic way to make dynamic UI for the applications.

Last but not least it’s Redux. Redux its a beautiful way to manage an application state. We’ll use the Redux-Toolkit library – it simplifies the work with Redux.
