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

The rows in the venue body are the same as before, except we are passing the number of tickets to buy as a new prop in the object.



The `Row` component has gotten a lot more functionality, some of which has been taken from the `Seat` component. In this version of the code, the status of a seat depends on the status of the seats next to it---if the tickets to buy number is two, then a set with an already sold seat next to it is not available. Because an individual seat can no longer contain all the data needed to ascertain it's status, the status for the entire row now needs to be stored in the `Row` component.

Here's the `Row` code:
