reduce rails dependencies

[BenMorganIO]

Hey there,

I noticed that your ruby gem was including all of rails. I've trimmed it down quite a bit to just the dependencies that this gem really needs.

A problem I encountered was that the test coverage didn't seem very good and the build was failing upon install. Please take a look at this problem in the future.

For the more optional dependencies, I would add them as either optional or as development dependencies.

@BenMorganIO Hey Ben! Thanks for the PR. Can you share your use case where you use this gem outside of rails, please? We also have a lower-level rack-based gem, would that fit your use case better?

[BenMorganIO]

It's fairly standard. My application will not need to use action cable or action text. So I instead opt for the individual rails deps. This way I don't have to pull in as many dependencies into my application.

Hi @BenMorganIO Thanks! This looks good - ignore the failing tests, looks like we have some setup issues in there for a couple of ruby versions.

I'd be happy to merge this, but I would like to understands how this affects your particular use case.

Would you be able to provide an example Gemfile and an application config with which I would be able to reproduce this gem requiring more than the original app was?

[BenMorganIO]

Here's an example section of a Gemfile where we replace the gem 'rails', '~> 7.0.4' with instead selecting which gems we want:

# Not using: actioncable actionmailbox actiontext
RAILS_DEPENDENCIES = %w[
  activesupport actionpack actionview activemodel activerecord actionmailer
  activejob activestorage
].freeze

RAILS_DEPENDENCIES.each { |dep| gem dep, '~> 7.0.4' }

Now that there's no action cable, action mailbox, or action text. My application is smaller, should in theory startup quicker, and I will have less of a time in dependency hell doing updates.

If my Rails app were API only and I wasn't sending any emails out or storing anything (perhaps just adding an API layer over the database), I could in theory reduce it even further by yanking active storage and action mailer, which would in turn remove a large amount of dependencies that they carry.

This also helps with security by only pulling in the dependencies that you need.

Thanks @BenMorganIO, sorry about taking so long to get this reviewed and merged!
I've released this as version 0.1.7
