Overview of this book

If you’re an existing Java developer who wants to go full stack or pick up another frontend framework, this book is your concise introduction to React. In this three-part build-along, you’ll create a robust Spring Boot backend, a React frontend, and then deploy them together. This new edition is updated to Spring Boot 3 and includes expanded content on security and testing. For the first time ever, it also covers React development with the in-demand TypeScript. You’ll explore the elements that go into creating a REST API and testing, securing, and deploying your applications. You’ll learn about custom Hooks, third-party components, and MUI. By the end of this book, you'll be able to build a full stack application using the latest tools and modern best practices.

OpenWeather API

First, we will make a React app that shows the current weather in London. We will show the temperature, description, and weather icon in our app. This weather data will be fetched from OpenWeather (https://openweathermap.org/).

You need to register with OpenWeather to get an API key. A free account will be sufficient for our needs. Once you have registered, navigate to your account information to find the API keys tab. There, you’ll see the API key that you need for your React weather app:

Your API key will be activated automatically, up to 2 hours after your successful...
