Discover the current landscape of full-stack development and how to leverage modern web technologies for building production-ready React.js applications to deploy on AWSKey FeaturesUnderstand the architecture of React and single-page applicationsBuild a modern Web API for your SPA using Node.js, Express, and GraphQLGain a clear and practical understanding of how to build a complete full-stack applicationBook DescriptionReact sets the standard for building high-performance client-side web apps. Node.js is a scalable application server that is used in thousands of websites, while GraphQL is becoming the standard way for large websites to provide data and services to their users. Together, these technologies, when reinforced with the capabilities of TypeScript, provide a cutting-edge stack for complete web application development. This book takes a hands-on approach to implementing modern web technologies and the associated methodologies for building full-stack apps. You’ll begin by gaining a strong understanding of TypeScript and how to use it to build high-quality web apps. The chapters that follow delve into client-side development with React using the new Hooks API and Redux. Next, you’ll get to grips with server-side development with Express, including authentication with Redis-based sessions and accessing databases with TypeORM. The book will then show you how to use Apollo GraphQL to build web services for your full-stack app. Later, you’ll learn how to build GraphQL schemas and integrate them with React using Hooks. Finally, you’ll focus on how to deploy your application onto an NGINX server using the AWS cloud. By the end of this book, you’ll be able to build and deploy complete high-performance web applications using React, Node, and GraphQL.What you will learnDiscover TypeScript’s most important features and how they can be used to improve code quality and maintainabilityUnderstand what React Hooks are and how to build React apps using themImplement state management for your React app using ReduxSet up an Express project with TypeScript and GraphQL from scratchBuild a fully functional online forum app using React and GraphQLAdd authentication to your web app using RedisSave and retrieve data from a Postgres database using TypeORMConfigure NGINX on the AWS cloud to deploy and serve your appsWho this book is forThe book is for web developers who want to go beyond front-end web development and enter the world of full-stack web development by learning about modern web technologies and how they come together. A good understanding of JavaScript programming is required before getting started with this web development book.

A no-nonsense guide to getting started with TestCafe quickly by building a complete test suite while learning the core concepts of test automation with TestCafe Key Features Build a proof-of-concept project to demonstrate your familiarity with TestCafe Discover useful tips and best practices for building production-ready and fault-tolerant tests Write clean and maintainable tests by refactoring your codebase using PageObject pattern Book Description TestCafe is an open source end-to-end testing framework that combines unmatched ease of use with advanced automation and robust built-in stability mechanisms. This book is a comprehensive, project-based introduction to TestCafe that will show you how to use the TestCafe framework and enable you to write fast and reliable tests; plus you'll have a proof of concept ready to demonstrate the practical potential of TestCafe. You'll begin by learning how to write end-to-end web tests using the TestCafe syntax and features of the TestCafe framework. You'll then go from setting up the environment all the way through to writing production-ready tests. You'll also find out how to build a sample set of tests in a step-by-step manner and use TestCafe to log in to the website, verify the elements present on different pages, create/delete entities, and run custom JavaScript code. As you advance, you'll delve into several stages of refactoring that will take you through the showcase setup/teardown and PageObject patterns. While this test suite is relatively simple to build, it showcases some of the most prominent features of TestCafe. Finally, this TestCafe book will show you how the tests can be run on a free and simple-to-use website, without requiring you to build and deploy your own servers or backend services. By the end of this book, you'll have learned how to write and enhance end-to-end tests with TestCafe to solve real-world problems and deliver results. What you will learn Understand the basic concepts of TestCafe and how it differs from classic Selenium Find out how to set up a TestCafe test environment Run TestCafe with command-line settings Verify and execute TestCafe code in the browser Automate end-to-end testing with TestCafe using expert techniques Discover best practices in TestCafe development and learn about the future roadmap of TestCafe Who this book is for The book is for QA professionals, test engineers, software engineers, and test automation enthusiasts looking for hands-on guidance on l...
