Full-Stack Web Development with GraphQL and React - Second Edition

By: Sebastian Grebe

Overview of this book

React and GraphQL, when combined, provide you with a very dynamic, efficient, and stable tech stack to build web-based applications. GraphQL is a modern solution for querying an API that represents an alternative to REST and is the next evolution in web development. This book guides you in creating a full-stack web application from scratch using modern web technologies such as Apollo, Express.js, Node.js, and React. First, you’ll start by configuring and setting up your development environment. Next, the book demonstrates how to solve complex problems with GraphQL, such as abstracting multi-table database architectures and handling image uploads using Sequelize. You’ll then build a complete Graphbook from scratch. While doing so, you’ll cover the tricky parts of connecting React to the backend, and maintaining and synchronizing state. In addition to this, you’ll also learn how to write Reusable React components and use React Hooks. Later chapters will guide you through querying data and authenticating users in order to enable user privacy. Finally, you’ll explore how to deploy your application on AWS and ensure continuous deployment using Docker and CircleCI. By the end of this web development book, you'll have learned how to build and deploy scalable full-stack applications with ease using React and GraphQL.

Integrating Sequelize into our Node.js stack

We have just set up a MySQL database, and we want to use it inside of our Node.js backend. There are many libraries to connect to and query your MySQL database. We are going to use Sequelize in this book.

Alternative Object–Relational Mappers (ORMs)

Alternatives include Waterline ORM and js-data, which offer the same functionalities as Sequelize. What is great about these is that they not only offer SQL dialects, but also feature database adapters for MongoDB, Redis, and more. So, if you need an alternative, check them out.

Sequelize is an ORM for Node.js. It supports the PostgreSQL, MySQL, SQLite, and MSSQL standards.

Install Sequelize in your project via npm. We will also install a second package, called mysql2:

npm install --save sequelize mysql2

The mysql2 package allows Sequelize to speak with our MySQL server.

Sequelize is just a wrapper around the various libraries for the different database systems. It...
