While learning React, most people develop and test their apps locally. I mean … they’re just demo apps for learning purposes right? Nobody wants to see stuff like that, so why even think of deploying the apps somewhere?
This might sound familiar to you: You run your React app after you made some changes to test your new functionality and get an error message like this: “this.setState’ is not a function“. It’s probably because you forgot to bind a callback function before passing it down a prop. Today you’ll learn why you need to bind, and how to bind a callback function in React.
Hello again! Did you ever try to display data from a remote backend in your React app? In the third part of this article series, you will learn how to fetch data from a REST API and use it inside your app.
Setting up a React app can be confusing, since you have to take care of a lot of stuff that you don’t want to think about—at least at the beginning of your React journey.

It’s almost impossible to know all of the available frameworks and technologies, frontend or backend. But somehow you still have to choose a technology stack, or you will never start building. In this article I’ll show you how to handle this problem in the beginning until you’ve built the necessary experience. Continue reading Choosing a Technology Stack for your Project
Functional components are simpler and easier to test in comparison to class components. However, both of them have pros and cons and today you’ll learn the differences and when to use which type of components.
React PropTypes are a good way to help you catching bugs by validating data types of values passed through props. They also offer possibilities to flag props as mandatory or set default values. They provide a great benefit with little effort.
