I haven’t developed in Rails for a number of years, but having recently had the oppourtinity to use it again, I have some picked up some tricks and tips.

These tips relate to the current version of Rails, 6.1.4.

You can check where a rake task is defined by running -W:

bundle exec rake -W assets:precompile

You should pin sassc to 2.1.0 to prevent building with native extensions in CI systems, as later versions didn’t ship with them (source).

The bin/ files that are created when you run rails new are imporant, and some code will complain if you remove them.

More as I find them!
