Jussi Roine, Olli Jääskeläinen

SharePoint is one of Microsoft's best known web platforms. A loyal audience of developers, IT Pros and power users use it to build line of business solutions. The SharePoint Framework (SPFx) is a great new option for developing SharePoint solutions. Many developers are creating full-trust based solutions or add-in solutions, while also figuring out where and how SPFx fits in the big picture. This book shows you how design, build, deploy and manage SPFx based solutions for SharePoint Online and SharePoint 2016. The book starts by getting you familiar with the basic capabilities of SPFx. After that, we will walk through the tool-chain on how to best create production-ready solutions that can be easily deployed manually or fully automated throughout your target Office 365 tenants.We describe how to configure and use Visual Studio Code, the de facto development environment for SPFx-based solutions. Next, we provide guidance and a solid approach to packaging and deploying your code. We also present a straightforward approach to troubleshooting and debugging your code an environment where business applications run on the client side instead of the server side.

Simplify Testing with React Testing Library. Create maintainable tests using RTL that do not break with changes

Scottie Crump

React Testing Library (RTL) is a lightweight and easy-to-use tool for testing the document object model (DOM) output of components. This book will show you how to use this modern, user-friendly tool to test React components, reducing the risk that your application will not work as expected in production.The book demonstrates code snippets that will allow you to implement RTL easily, helping you to understand the guiding principles of the DOM Testing Library to write tests from the perspective of the user. You'll explore the advantages of testing components from the perspective of individuals who will actually use your components, and use test-driven development (TDD) to drive the process of writing tests. As you advance, you'll discover how to add RTL to React projects, test components using the Context API, and also learn how to write user interface (UI) end-to-end tests using the popular Cypress library. Throughout this book, you’ll work with practical examples and useful explanations to be able to confidently create tests that don't break when changes are made.By the end of this React book, you will have learned all you need to be able to test React components confidently.

Single Page Web Applications. Programowanie aplikacji internetowych z JavaScript

Michael Mikowski, Josh Powell

Gdy uruchamiasz aplikację na swoim komputerze, tak naprawdę nie wiesz, czy jest to tradycyjna aplikacja działająca na Twoim sprzęcie czy też może aplikacja internetowa. Nie widać przejść między stronami, a atrakcyjny interfejs użytkownika pozwala Ci błyskawicznie wykonać konieczne zadania. Być może za wyświetlanie interfejsu odpowiedzialna jest wyłącznie przeglądarka, która z serwerem komunikuje się tylko w celu wymiany danych. Tak właśnie działają jednostronicowe aplikacje internetowe (ang. Single Page Applications). Jeżeli masz pomysł na taką aplikację, a nie wiesz, od czego zacząć, sięgnij po tę książkę. Dzięki niej zbudujesz swoją pierwszą jednostronicową aplikację internetową oraz poznasz możliwości współczesnego języka JavaScript. W kolejnych rozdziałach będziesz budować aplikację, jednocześnie zdobywając wiedzę na temat wzorca MVC, modelu danych, modułów oraz interfejsu. Kiedy już opanujesz tworzenie klienta, przyjdzie czas na implementację serwera. Jest on odpowiedzialny za przetwarzanie danych otrzymywanych z przeglądarki. W trakcie lektury poznasz możliwości Node.js oraz skonfigurujesz bazę danych. Na sam koniec przygotujesz Twoją aplikację do pracy w środowisku produkcyjnym. Dzięki tej książce: poznasz możliwości języka JavaScript skorzystasz ze wzorca MVC zbudujesz jednostronicową aplikację internetową skonfigurujesz serwer współdziałający z Twoją aplikacją wykorzystasz potencjał Node.js Zbuduj swoją pierwszą jednostronicową aplikację internetową!

Solidity Programming Essentials. A beginner's guide to build smart contracts for Ethereum and blockchain

Ritesh Modi

Solidity is a contract-oriented language whose syntax is highly influenced by JavaScript, and is designed to compile code for the Ethereum Virtual Machine.

Solidity Programming Essentials. A guide to building smart contracts and tokens using the widely used Solidity language - Second Edition

Ritesh Modi

Solidity is a high-level language for writing smart contracts, and the syntax has large similarities with JavaScript, thereby making it easier for developers to learn, design, compile, and deploy smart contracts on large blockchain ecosystems including Ethereum and Polygon among others. This book guides you in understanding Solidity programming from scratch.The book starts with step-by-step instructions for the installation of multiple tools and private blockchain, along with foundational concepts such as variables, data types, and programming constructs. You’ll then explore contracts based on an object-oriented paradigm, including the usage of constructors, interfaces, libraries, and abstract contracts. The following chapters help you get to grips with testing and debugging smart contracts. As you advance, you’ll learn about advanced concepts like assembly programming, advanced interfaces, usage of recovery, and error handling using try-catch blocks. You’ll also explore multiple design patterns for smart contracts alongside developing secure smart contracts, as well as gain a solid understanding of writing upgradable smart concepts and data modeling. Finally, you’ll discover how to create your own ERC20 and NFT tokens from scratch.By the end of this book, you will be able to write, deploy, and test smart contracts in Ethereum.
