Did you know that Rails has a ~/.railsrc
file?
Similar to your ~/.bashrc
or ~/.zshrc
file, you can use this file to configure your Rails applications.
This is especially useful if you find yourself repeatedly typing --skip
or --no-skip
commands and installing specific gems every time you create a new Rails application.
Since I made a switch to Rails from .NET last year, I must have created at least 20-30 projects for either learning, experiments, or client work. I have a text file that documents all the gems I want to install for a fresh Rails app. Every time I create a new project, I go through the file to install all the gems I want for my project.
With the ~/.railsrc
file, I don't need to do that. Rails will do it for me. Here's how you do this.
First, create the .railsrc
file in your home directory.
touch ~/.railsrc
Add whatever options you want in this file. For example,
--database=mysql
--skip-active-job
--skip-spring
--skip-javascript
--template=~/dotfiles/rails_template.rb
To see all the available options, type rails
in a non-rails directory.
➜ rails rails
Usage:
rails new APP_PATH [options]
Options:
[--skip-namespace], [--no-skip-namespace] # Skip namespace (affects only isolated engines)
[--skip-collision-check], [--no-skip-collision-check] # Skip collision check
-r, [--ruby=PATH] # Path to the Ruby binary of your choice
# Default: /Users/akshay/.rbenv/versions/3.1.0/bin/ruby
-m, [--template=TEMPLATE] # Path to some application template (can be a filesystem path or URL)
-d, [--database=DATABASE] # Preconfigure for selected database
...
To pre-configure the gems you'd like to install, create a template.rb
file. Here's mine:
gem_group :development, :test do
gem 'dotenv-rails'
gem 'factory_bot_rails'
end
gem_group :development do
gem 'better_errors'
gem 'binding_of_caller'
gem 'annotate'
end
Now add the path to the template at the end of your ~/.railsrc
file.
--template=~/software/rails/template.rb
That's it. The next time you run rails new app
, Rails will use the configuration file along with the Gemfile
template to create your application just like you want.
Pretty cool, right?
