React 16 Essentials. A fast-paced, hands-on guide to designing and building scalable and maintainable web apps with React 16 - Second Edition

Artemij Fedosejev, Adam Boduch

React 16 Essentials, Second Edition, fully updated for React 16, takes you on a fast-paced journey through building your own maintainable React 16 applications. React experts Artemij Fedosejev and Adam Boduch give you all the essentials you need to know and start working with React 16, in this new edition of the best-selling React.js Essentials title. You'll find the latest React 16 code updates, assessment of React Fiber, new coverage of Redux, and how to work as a modern React developer.The authors offer you their current assessment of React Fiber, and you'll soon be exploring React 16 hands on, creating your own single and multiple user interface elements with React 16. You'll then see how to create stateless and stateful components and make them reactive. You'll also learn to interact between your components and lifecycle methods, and gauge how to effectively integrate your user interface components with other JavaScript libraries. Delve deep into the core elements of the Redux architecture and learn how to manage your application and data persistence. Then go the extra mile with the Jest test framework, and run multiple tests on your applications and find solutions to scale without complexity.Today React is used by Facebook, Instagram, Khan Academy, and Imperial College London, to name a few. Many new users recognize the benefits of React and adopt it in their own projects, forming a fast-growing community.

React 16 Tooling. Master essential cutting-edge tools, such as create-react-app, Jest, and Flow

Adam Boduch

React 16 Tooling covers the most important tools, utilities, and libraries that every React developer needs to know — in detail. As React has grown, the amazing toolset around it has also grown, adding features and enhancing the development workflow. Each of these essential tools is presented in a practical manner and in a logical order mirroring the development workflow. These tools will make your development life simpler and happier, enabling you to create better and more performant apps.Adam starts with a hand-picked selection of the best tools for the React 16 ecosystem. For starters, there’s the create-react-app utility that’s officially supported by the React team. Not only does this tool bootstrap your React project for you, it also provides a consistent and stable framework to build upon. The premise is that when you don’t have to think about meta development work, more focus goes into the product itself.Other React tools follow this same approach to automating and improving your development life. Jest makes unit testing quicker. Flow makes catching errors easier. Docker containers make deployment in a stack simpler. Storybook makes developing components straightforward. ESLint makes writing standardized code faster. The React DevTools plugin makes debugging a cinch. React 16 Tooling clears away the barriers so you can focus on developing the good parts. In this book, we’ll look at each of these powerful tools in detail, showing you how to build the perfect React ecosystem to develop your apps within.

React 17. Wzorce projektowe i najlepsze praktyki. Projektowanie i rozwijanie nowoczesnych aplikacji internetowych. Wydanie III

Carlos Santana Roldán

JavaScript pozwala na tworzenie znakomitego kodu, ale wymaga od programisty sporych umiejętności. Tworzenie nawet bardzo złożonych aplikacji jest jednak łatwiejsze dzięki dostępnym narzędziom. Szczególnym uznaniem cieszy się React - popularna biblioteka open source służąca do tworzenia dynamicznych aplikacji na bazie niewielkich komponentów wielokrotnego użytku. React jest narzędziem, które w stosunkowo prosty sposób pozwala w pełni skorzystać z możliwości nowoczesnych przeglądarek i urządzeń mobilnych. To książka przeznaczona dla średnio zaawansowanych użytkowników biblioteki React, którzy chcą tworzyć elastyczniejsze i łatwiejsze w utrzymaniu aplikacje. Wyjaśniono tu sposób działania wewnętrznych mechanizmów biblioteki React. Zaprezentowano, jak należy budować komponenty możliwe do wielokrotnego użycia, jak projektować strukturę aplikacji, a także omówiono zasady tworzenia poprawnych formularzy. Opisano też procesy definiowania stylów dla komponentów biblioteki React, jak również ich optymalizowania w celu przyspieszenia aplikacji i zwiększenia ich responsywności. Nie zabrakło szczegółowego omówienia technik tworzenia zestawów efektywnych testów, ponadto znalazły się tutaj informacje na temat korzystania z takich narzędzi jak służący do testowania Enzyme, React Router czy ułatwiający ciągłą integrację CircleCI. Zdobywanie umiejętności niezbędnych do zbudowania działającej aplikacji ułatwiają liczne przykłady, wskazówki i fragmenty kodu. W książce między innymi: składniki biblioteki React, w tym Context API i React hooks tworzenie i optymalizacja komponentów stosowanie języka GraphQL w projektach renderowanie po stronie serwera tworzenie wydajnego zestawu testów techniki optymalizacji komponentów React: nowy wymiar efektywnego programowania aplikacji!
