Continuous changes in business requirements can make it difficult for programmers to organize business logic into database models, which turns out to be an expensive operation as changes to the database may result in errors and incongruity within applications. Supercharging Node.js Applications with Sequelize helps you get to grips with Sequelize, a reliable ORM that enables you to alleviate these issues in your database and applications.
With Sequelize, you'll no longer need to store information in flat files or memory. This book takes a hands-on approach to implementation and associated methodologies for your database that will have you up and running in no time. You'll learn how to configure Sequelize for your Node.js application properly, develop a better sense of understanding of how this ORM works, and find out how to manage your database from Node.js using Sequelize. Finally, you'll be able to use Sequelize as the database driver for building your application from scratch.
By the end of this Node.js book, you'll be able to configure, build, store, retrieve, validate, and associate your data from a database to a Node.js application.
Review
"Sequelize is a modern ORM that supports many different SQL dialects. Sequelize was born during the early days of the JavaScript runtime Node.js. It was the first of its kind and was presented as a tool for the Node.js community to connect against existing relational databases, or to embrace them in new projects despite the rising trend of document stores. Ever since its release, a strong team of driven engineers added battle-tested support for transactions, relations, eager/lazy loading, read replication, and so much more. Twelve years on, the Sequelize project is part of npm's top 100, and sees wide adoption by huge enterprises and small pet projects alike.Daniel Durante joined the team in 2013 and contributed immensely to the library's Postgres support by improving the general stability, but also via features such as HStore capabilities and pooling. Furthermore, and maybe most importantly, he was also the one behind the introduction of hooks and object lifecycles, which is now one of the core mechanics used to interact with data objects. This book will guide you through all the steps of app development, starting with the very ideation of an app, to the modeling of entities and defi nition of business requirements, all the way to the implementation and deployment of a project. Throughout this journey you'll learn how to grow a small pet project into a stable and scalable application that is free of unwanted side-effects, that caters for auditing of user actions, and can be easily extended going forward. Enjoy your ride and welcome to the world of databases!"
