In this course, you will learn to build a fully-functional application with Rails Webpacker, Webpack, and TypeScript.

To kick things off, you’ll walk through the basics of getting Rails set up to use Webpacker which will serve JavaScript and CSS to the browser. You’ll then get acquainted with Stimulus and React which will help with creating richer interactions.

In the latter half, you’ll work with TypeScript and set up communication between a server. Beyond that, you’ll work through managing state in your Stimulus code, as well as how to test and troubleshoot your application.

By the end of this course, you will be well equipped to create larger, more complex applications that make use of modern tools.

Modern Front-end Development for Rails



Now that we've implemented some show/hide toggle interactivity using TypeScript without a JavaScript framework and started to feel some of the difficulty there, it's time to look at a tool that makes writing these interactive parts much easier. We have a schedule page in our sample app, and it’s got some filters that haven’t been implemented yet.

In this chapter, we're going to use the Stimulus library to start adding these features. Along the way, we’ll explore Stimulus’ basic concepts and then combine those concepts to build complex functionality into our app.


Get an overview of how Stimulus allows us to build complex interactive functionality into our app.
