Rails 6.1 adds --minimal option support

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.

# before Rails 6.1

$ rails new tiny_app
    --skip-action-cable
    --skip-action-mailer
    --skip-action-mailbox
    --skip-action-text
    --skip-active-storage
    --skip-bootsnap
    --skip-javascript
    --skip-spring
    --skip-system-test
    --skip-webpack-install
    --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.

$ rails new tiny_app --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
• webpack

We can bundle webpack in this minimal app like this.

$ rails new tiny_app --minimal webpack=react

Database option can also be passed.

$ rails new tiny_app --minimal --database postgresql webpack=react
