Why is GraphQL the most innovative technology for fetching data since Ajax? By providing a query language for your APIs and a runtime for fulfilling queries with your data, GraphQL presents a clear alternative to REST and ad hoc web service architectures. With this practical guide, Alex Banks and Eve Porcello deliver a clear learning path for frontend web developers, backend engineers, and project and product managers looking to get started with GraphQL. You’ll explore graph theory, the graph data structure, and GraphQL types before learning hands-on how to build a schema for a photo-sharing application. This book also introduces you to Apollo Client, a popular framework you can use to connect GraphQL to your user interface. Explore graph theory and review popular graph examples in use today Learn how GraphQL applies database querying methods to the internet Create a schema for a PhotoShare application that serves as a roadmap and a contract between the frontend and backend teams Use JavaScript to build a fully functioning GraphQL service and Apollo to implement a client Learn how to prepare GraphQL APIs and clients for production
Learn how to get started with GraphQL, the popular query language designed to make data fetching and updating easier.
Build data-driven React applications with ease using GraphQL and Relay About This Book Take your React applications to the next level with GraphQl and Relay Explore the concepts of data fetching, data handling, and more Learn to deploy your applications, which are compliant with GraphQl and Relay Who This Book Is For This book is perfect for those who have no prior experience or familiarity with Relay and/or GraphQL. You should be comfortable writing NodeJS applications on a MongoDB database with REST APIs as well as applications on the client-side using React and ES2015. What You Will Learn Understand what problem GraphQL solves and how it differs from traditional REST architectures Create a GraphQL server Develop modular and maintainable GraphQL code Grasp how to define GraphQL mutations Comprehend how to define GraphQL queries Modify a GraphQL server to be Relay-compliant Develop a Relay client-side application with ReactJS that consumes a GraphQL endpoint In Detail There's a new choice for implementing APIs – the open source and Facebook-created GraphQL specification. Designed to solve many of the issues of working with REST, GraphQL comes alongside RelayJS, a React library for querying a server that implements the GraphQL specification. This book takes you quickly and simply through the skills you need to be able to build production ready applications with both GraphQL and RelayJS. Beginning with a solid foundation in the GraphQl specification, this book swiftly moves to how a data layer can be implemented for your web application using Relay. Get to grips with GraphQL and Relay concepts creating data containers, data masking, and more as your progress towards building a production-ready application. Style and approach This book serves as the answer to every question related to data-driven app development with React. Using real-world examples, this book will show you how to enhance the functionality of React apps by introducing efficient data handling features within the app.
"GraphQL is a query language for APIs and a runtime for fulfilling those queries with your existing data. GraphQL provides a complete and understandable description of the data in your API. In this course, we will learn about GraphQL and how we can use it to create truly decoupled client and server. Writing backend with GraphQL makes our code more declarative wherein the client demands certain data in a particular format and the server responds in a predictable manner. This enables us to evolve our API without versions and iterate on features faster. For front-end and networking, we will use Facebook's React and Relay respectively. We will learn GraphQL by creating a backend for a blog platform. You will learn about GraphQL schema design, authentication, pagination, testing, query batching and more and how to connect a GraphQL backend to React and Relay client. The course will teach everything to get up and running with GraphQL and React."--Resource description page.

Want to build APIs like Facebook? Since Facebook's framework for building APIs, GraphQL, has become publicly available, this ambition seems to be within reach for many companies. And that is great. But first, let's learn what GraphQL really is and - maybe even more importantly - let's figure out how to apply GraphQL to build APIs that consumers love. Do you like to learn hands-on? In this book, we take a hands-on approach to learning GraphQL. We first explore the concepts of the two GraphQL languages using examples. Then we start writing some code for our first GraphQL API. We develop this API step by step, from creating a schema and resolving queries, over mocking data and connecting data sources all the way to developing mutations and setting up event subscriptions. Are your API consumers important to you? This book shows you how to apply a consumer-oriented design process for GraphQL APIs, so you can deliver what your consumers really want: an API that solves their problems and offers a great developer experience. Do you want to enable the API consumers so they can build great apps? This book explains the GraphQL query language, which allows the API consumers to retrieve data, write data and get notified when data changes. More importantly, you let them decide, which data they really need from the API. Do you want to make your API easy and intuitive to use? This book shows you how to use the GraphQL schema language to define a type system for your API, which serves as a reference documentation and helps your API consumers write queries that are syntactically correct. Do you want to profit from what has worked for others? This book provides a collection of best practices for GraphQL that have worked for other companies, e.g. regarding pagination, authentication and caching. REST vs. GraphQL: Which one is better? GraphQL and REST are competing philosophies for building APIs. It is not in the scope of this book to compare or discuss the two approaches. The focus of this book is on a hands-on approach for learning GraphQL.
