What an exciting couple of months it has been for the Rails community! Rails 7 was released in December of 2021 and this month we are welcoming Propshaft. David Heinemeier Hansson (DHH), the creator of Rails, released a post on Feb. 11 introducing the community to the new and improved asset pipeline for Rails. While Propshaft likely won't be the default until at least Rails 8, it promises a simpler solution to asset management over its predecessor, Sprockets. Sprockets, the current default asset pipeline library, has grown increasingly heavy over the years as it has attempted to shoulder all things related to bundling, minifying, transpiling, and compressing. Enabled by the new era of tech that makes Rails 7 possible, Propshaft is touted as being "absolutely tiny" in comparison and aims to provide the following: a configurable load path for your assets, digest stamping for long-expiry cache and better performance, a development server that removes the need to pre-compile assets, and basic compilers instead of full transpilers. Sprockets will require relatively long-term support and will remain the default for now but fret not! You can create a Rails 7+ app using Propshaft, or upgrade an existing app and start using it now.
