React Quickly is the companion source code repository for the book React Quickly: Painless Web Apps with React, JSX, Redux, and GraphQL published by Manning in 2017. The project provides practical examples and code samples that accompany the book, covering essential modern web development topics including React component architecture, JSX syntax, state management with Redux, and data fetching with GraphQL. It serves as a hands-on learning resource for developers who want to build efficient web applications using the React ecosystem. The repository includes working code projects that demonstrate core React concepts, simple and complex component patterns, routing, forms, testing, and integration with Redux for application state. Users can clone the repository, follow along with book chapters, and experiment with fully functional projects to deepen their understanding of React and its related technologies. Additional information about the book is available through Manning Publications.
