Up to this point, you have been using the Microblog API back end with an option to bypass authentication. This enabled the project to grow without having to deal with the highly complex matter of user authentication up front. In this chapter you will finally learn how to do this.

A big part of most web applications is accepting, validating and processing user input. In this chapter you are going to learn how to perform these tasks with React by creating the user registration and login forms for Microblog.

In Chapter 5, the Posts component was modified to make an API call that gets data from the server. The way it was done, however, does not scale very well, because as the application continues to grow, there's going to be other components that will also need to make their API calls, and having to repeat the API calling logic in several places will be difficult to manage, especially considering that these calls are going to become more complex once authentication and pagination are implemented.

It's been almost a year since I published my Beautiful Interactive Tables for your Flask Templates article, in which I showed a few example tables, rendered from a standard Flask and Jinja template, with some JavaScript help.

I have received a good amount of feedback on my proposed solutions. In this article I'm going to refresh my table examples to address the two most frequently requested improvements.

In this chapter you are going to learn how the React application can communicate with a back end application to request data. While doing this, you will learn how to use the two most important React hooks: useState() and useEffect().

React is a Single-Page Application (SPA) framework, which means that from the point of view of the browser, only one web page is ever downloaded. Once that page is active, all the application state changes will happen through JavaScript events, without the browser having to fetch new web pages from the server. How then, can the application support page navigation?

In Chapter 2, you wrote your first React component. In this chapter you will delve deeper into React as you learn how to create robust applications by combining and reusing components, not only your own but also some imported from third-party libraries.

In this chapter you will take your first steps as a React developer. When you reach the end you will have a first version of a microblogging application running on your computer!

The JavaScript language has evolved significantly in the last few years, but because browsers have been slow in adopting these changes a lot of people have not kept up with the language. React encourages developers to use modern JavaScript, so this chapter gives you an overview of the newest features of the language.

Welcome to the React Mega-Tutorial! In this series I will share my experience in developing real-world, non-trivial front end applications using the React library and a handful of related packages.

Unlike most other books and tutorials, the React Mega-Tutorial will take you on a development journey. Instead of teaching you React concepts with isolated examples, it will show you how to develop a complete front end application. You will begin by creating a brand new React project, and then start adding features and functionality to it as you progress through the chapters. When you reach the end, you will have a complete project of which you will understand every single line of code. More importantly, you will understand the concepts and techniques involved in creating it, in way that will be directly applicable to your own projects.
