Hands-on Full-Stack Web Development with GraphQL and React

By: Sebastian Grebe

Overview of this book

React, one of the most widely used JavaScript frameworks, allows developers to build fast and scalable front end applications for any use case. GraphQL is the modern way of querying an API. It represents an alternative to REST and is the next evolution in web development. Combining these two revolutionary technologies will give you a future-proof and scalable stack you can start building your business around. This book will guide you in implementing applications by using React, Apollo, Node.js and SQL. We'll focus on solving complex problems with GraphQL, such as abstracting multi-table database architectures and handling image uploads. Our client, and server will be powered by Apollo. Finally we will go ahead and build a complete Graphbook. While building the app, we'll cover the tricky parts of connecting React to the back end, and maintaining and synchronizing state. We'll learn all about querying data and authenticating users. We'll write test cases to verify the front end and back end functionality for our application and cover deployment. By the end of the book, you will be proficient in using GraphQL and React for your full-stack development requirements.

Pagination in React and GraphQL

By pagination, most of the time, we mean the batch querying of data. Currently, we query for all posts, chats, and messages in our database. If you think about how much data Facebook stores inside one chat with your friends, you will realize that it is unrealistic to fetch all of the messages and data ever shared at once. A better solution is to use pagination. With pagination, we always have a page size, or a limit, of how many items we want to fetch per request. We also have a page, or offset number, from which we can start to select data rows.

In this section, we're going to look at how to use pagination with the posts feed, as it is the most straightforward example. In the Chapter 5, Reusable React Components, we will focus on writing efficient and reusable React code. Sequelize offers the pagination feature by default. We can first insert...
