Experiment with the Redux chapter samples to understand how state flows through a multi-component React app before applying it to your own project.

USE CASE 3

Use the React 16 updated code to compare against the older book examples and understand what changed between versions.

USE CASE 4

In plain English

This repository holds all the code samples that go along with the book "Learning React" by Alex Banks and Eve Porcello, published by O'Reilly Media. If you bought the book and want to follow along with working examples, this is where you find them organized by chapter. React is a JavaScript library for building user interfaces, and the book targets people who are curious about React but are not sure where to begin. The chapters walk through foundational JavaScript concepts first, then move into React-specific topics like components, props, state, routing, and server rendering. Later chapters cover Redux, which is a common tool for managing data across a React application, along with testing. The repo is organized into folders for each of the book's twelve chapters. Each folder contains the runnable code for that part of the book. The repo notes that it has been updated to React 16, which is a newer version than the one used in the printed book. If you have the physical book and want the code to match exactly what is printed, an older tagged version of the repo (v1.0.0) is available for that purpose. The README files inside the individual chapter folders explain where the React 16 changes affect the examples. This is a companion resource to a published book, not a standalone tool or library. Its value is in giving readers code they can run, experiment with, and compare to what they read on the page.

Copy-paste prompts

Prompt 1
I'm on Chapter 5 of Learning React and the code isn't working. Here's the error: [paste error]. Show me what might be wrong and how to fix it based on common React component and props mistakes.
Prompt 2
I want to understand the Redux examples from Learning React Chapter 10. Walk me through how the store, reducers, and actions connect, using a simplified version of the book's example.
Prompt 3
I've cloned the learning-react repo and want to run the Chapter 3 examples. What commands do I need to install dependencies and start the dev server?
Prompt 4
Take the routing example from Learning React and show me how to update it from React Router v4 to the current version of React Router.
