I think everyone in the web development process was faced with the need to add a confirm dialog when performing some operation on the site. In this article, I want to write how to add and make an attractive confirm dialog in your Rails apps.

In Ruby on Rails, we have a confirm dialog out of the box, it's a very useful feature because you have the opportunity to easily and quickly create confirmation for some action in your site. In default Rails used for this standard JavaScript confirm (you can read about it in the documentation if you doesn't know it)

When we use gem parallel_tests our application in test environment used, for example, 8 parallel processes. But webpacker compiling the same files at the same time in each process. This is bad and can lead to unexpected errors.

Also when assets did not change, we do not want to spend time compiling them.
