Getting started

You can use online code editors to practice, or you can use Create React App.

I have setup a development environment in JSFiddle and in Codepen.

To grasp all the fundamentals of React, you can start with the following tutorials:

React official documentation by React

Beginners guide to React by Kent C. Dodds

Fundamentals of React by Samer Buna

By now, you should have a basic idea of the fundamentals of React. It’s enough to start developing simple web apps in React.

Now, take a look at the React official tutorial:

It’s a well-written article covering the fundamentals of React. And it also explains the specific topics very clearly.

Last but not least, learn how to connect to APIs with React apps:

2. Simple calculator app
3. Build a shopping cart
4. Display GitHub’s user stats using GitHub API

React Router

React Router helps you create routes to your single page applications. It’s very powerful and easy to use with your React application.

To get started:

React Router and intro to SPA by Learn Code Academy

Routing React apps by Scotch.io

These articles are more than enough for you to get started with React routing.

Projects

1. A simple CURD application
2. Hacker News clone

Webpack

Webpack is a famous JavaScript module bundler. Webpack helps you to maintain dependencies as static files for your project so developers don’t have to do it.

Webpack also comes with loaders. Loaders help run specific tasks around your project.

To learn much more about Webpack, follow the following tutorials.

When and why to use Webpack by Andrew Ray

To setup your local React environment using Webpack, you can refer to the following GitHub repo:

Server rendering

Server rendering is one of the coolest features in React. It can be used with any of the back-end technologies.

Server Side Rendering (SSR) in React helps you to create components in the server and render that as HTML in your browser. And when all the JavaScript modules are downloaded in the browser, React takes the stage. Simple!

First of all, take a look at the React-DOM API:

And follow the below tutorials to get in-depth knowledge:

Redux

Redux is a JavaScript library developed for maintaining application states. When you are building a complex application, it will add overhead to manage states across components. Redux helps you store all your states in a single source. And of course, React plays well with Redux 🙂
