Hello, Rails!

Let’s start easy by creating our application’s database and boot up our Rails server for the first time.

In your terminal, run the following commands in the store directory:

$ bin/rails db:create

This will initially create the application’s database.

$ bin/rails server

NOTE: When we run commands inside an application directory, we should use bin/rails. This makes sure the application’s version of Rails is used.

This will start up a web server that will serve static files and your Rails application:

=> Booting WASIServer
=> Rails 8.1.0 application starting in development
=> Run `bin/rails server --help` for more startup options
Express.js server started on port 3000
Use Ctrl-C to stop

In the preview pane to your right you should see the default Rails welcome page. If you can see it—everything works as expected!

This page is the smoke test for a new Rails application, ensuring that everything is working behind the scenes to serve a page.

To stop the Rails server anytime, press Ctrl-C in your terminal.
