Overview of this book

Next.js is a scalable and high-performance React.js framework for modern web development and provides a large set of features, such as hybrid rendering, route prefetching, automatic image optimization, and internationalization, out of the box. If you are looking to create a blog, an e-commerce website, or a simple website, this book will show you how you can use the multipurpose Next.js framework to create an impressive user experience. Starting with the basics of Next.js, the book demonstrates how the framework can help you reach your development goals. You'll realize how versatile Next.js is as you build real-world applications with step-by-step explanations. This Next.js book will guide you in choosing the right rendering methodology for your website, securing it, and deploying it to different providers, all while focusing on performance and developer happiness. By the end of the book, you'll be able to design, build, and deploy modern architectures using Next.js with any headless CMS or data source.

Global state management

When talking about the global application state, we refer to a state shared between all the components for a given web application that is, therefore, reachable and modifiable by any component.

As seen in the previous section, the React data flow is unidirectional, meaning that components can pass data to their children components, but not to their parents (unlike Vue or Angular). That makes our components less error prone, easier to debug, and more efficient, but adds extra complexity: by default, there cannot be a global state.

Let's take a look at the following scenario:
