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.

Using Sequelize with Apollo

The database object is initialized upon starting the server within the root index.js file. We pass it from this global location down to the spots where we rely on the database. This way, we do not import the database file repeatedly, but have a single instance that handles all database queries for us.

The services that we want to publicize through the GraphQL API need access to our MySQL database. The first step is to implement the posts into our GraphQL API. It should respond with the fake posts from the database we just inserted.

Global database instance

To pass the database down to our GraphQL resolvers, we create a new object in the server index.js file:

import db from './database&apos...
