Description

It’s hard to have a Rails application without integrating some client-side logic. But client-side coding tools, and the Rails tools for integrating with them, all change continuously. Rails 7 simplifies client-side integration with the Hotwire gem. It’s a great way to build client interaction with server-side HTML and a small amount of JavaScript.

In the latest edition of this book, learn how to use Rails 7 and its front-end bundling tools to build rich front-end logic into your Rails applications. The job is even easier with Stimulus, a library that brings Rails conventions to JavaScript tools. And you can also add in React, a larger framework that automatically updates the browser when your data changes.

Learn the basics of Turbo, Stimulus, and TypeScript, and add pizazz to your application. Structure your web application to best manage your state. Learn how to interact with data on the server while still keeping the user experience interactive. Use the type system in TypeScript to expand on JavaScript and help prevent error conditions. Debug and test your front-end application with tools specific to each framework.

There are a lot of ways to do client-side coding, and Rails is here to help.
