Redux Made Easy with Rematch

By: Sergio Moreno

Overview of this book

Rematch is Redux best practices without the boilerplate. This book is an easy-to-read guide for anyone who wants to get started with Redux, and for those who are already using it and want to improve their codebase. Complete with hands-on tutorials, projects, and self-assessment questions, this easy-to-follow guide will take you from the simplest through to the most complex layers of Rematch. You’ll learn how to migrate from Redux, and write plugins to set up a fully tested store by integrating it with vanilla JavaScript, React, and React Native. You'll then build a real-world application from scratch with the power of Rematch and its plugins. As you advance, you’ll see how plugins extend Rematch functionalities, understanding how they work and help to create a maintainable project. Finally, you'll analyze the future of Rematch and how the frontend ecosystem is becoming easier to use and maintain with alternatives to Redux. By the end of this book, you'll be able to have total control of the application state and use Rematch to manage its scalability with simplicity.

Before optimizing, measure

Before jumping into this chapter, there's an idea that I would like to introduce: If you can't measure it, you can't optimize it. This seems straightforward enough, but sometimes we just forget this and focus on adding supposed performance optimizations where we probably don't need them, basically introducing technical debt where we shouldn't. Sometimes this technical debt becomes larger and larger and we lose control of our project as it becomes hard to maintain or, even worse, impossible to debug.

This might seem obvious, but sometimes it's not, and here we're going to learn how to measure – or at least learn about the main programs that we can use to benchmark – our application and see where it can be optimized.

Let's enumerate the three most important tools to track React performance issues and analyze how to fix them at runtime.
