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.

The Rematch select plugin

Selectors are a really good performance booster for our Rematch/Redux applications. A selector is simply a function that accepts the root state as an argument and returns data that is derived from that root state.

Reselect (https://github.com/reduxjs/reselect) is the official library for creating memoized and composable selector functions, and the Rematch select library is built on top of Reselect.

But why are selectors performance boosters? Because selectors aren't recomputed unless one of their arguments changes.

Installing and configuration

To install @rematch/select, you can use yarn and install it as follows:

yarn add @rematch/select

This package is just 596 bytes, so it has a minimal impact on our bundle size. None of the official Rematch plugins is more than 600 bytes in size.

This plugin accepts one optional argument, which is an object with the following properties:
