title: Is it possible/advisable to run Rails 6 without webpack(er)?
body: <p>I am starting a new Rails 6 application. If I understood correctly, Webpack(er) (<code>gem webpacker</code>) has replaced Sprockets as the new standard for including/minifying JS (<a href="https://blog.capsens.eu/how-to-write-javascript-in-rails-6-webpacker-yarn-and-sprockets-cdf990387463" rel="nofollow noreferrer">source</a>).
  Furthermore, Rails 6 now both requires <a href="https://guides.rubyonrails.org/getting_started.html#creating-a-new-rails-project-installing-rails" rel="nofollow noreferrer">Node.js and Yarn</a>.</p>
  <p>Am I correct in assuming that the Node.js and Yarn dependencies are only due to the inclusion of Webpack, or do other components of Rails 6 also need them?</p>
  <p>Are there any possible drawbacks in removing Webpack and Node and Yarn from the Rails 6 app and continuing to use the Rails Asset Pipeline (apart from missing Webpack features)?</p>
