Rails 6.1 adds --minimal option support

This blog is part of our Rails 6.1 series.

rails new my_app creates a new Rails application fully loaded with all the features.

If we want to omit some of the features then we needed to skip them like this.

1# before Rails 6.1
2
3$ rails new tiny_app
4    --skip-action-cable
5    --skip-action-mailer
6    --skip-action-mailbox
7    --skip-action-text
8    --skip-active-storage
9    --skip-bootsnap
10    --skip-javascript
11    --skip-spring
12    --skip-system-test
13    --skip-webpack-install
14    --skip-turbolinks

Before Rails 6.1 it was not possible to skip things like active_job and jbuilder.

Rails 6.1

Rails 6.1 added a new option --minimal.

All the following are excluded from this minimal Rails application.

  • action_cable
  • action_mailbox
  • action_mailer
  • action_text
  • active_job
  • active_storage
  • bootsnap
  • jbuilder
  • spring
  • system_tests
  • turbolinks

We can bundle webpack in this minimal app like this.

Database option can also be passed.
