This is the application template that I recommend for Rails 7 projects. I've assembled this template over the years to include best-practices, tweaks, documentation, and personal preferences, while still generally adhering to the "Rails way".
For older versions of Rails, use these branches:
This template currently works with:
- Rails 7.0.x
- Bundler 2.x
- PostgreSQL
If you need help setting up a Ruby development environment, check out my Rails OS X Setup Guide.
Optional.
To make this the default Rails application template on your system, create a ~/.railsrc
file with these contents:
-d postgresql
-m https://raw.githubusercontent.com/mattbrictson/rails-template/main/template.rb
This template assumes you will store your project in a remote git repository (e.g. GitHub) and that you will deploy to a production environment. It will prompt you for this information in order to pre-configure your app, so be ready to provide:
- The git URL of your (freshly created and empty) GitHub repository
- The hostname of your production server
To generate a Rails application using this template, pass the -m
option to rails new
, like this:
rails new blog \
-d postgresql \
-m https://raw.githubusercontent.com/mattbrictson/rails-template/main/template.rb
Remember that options must go after the name of the application. The only database supported by this template is postgresql
.
If you’ve installed this template as your default (using ~/.railsrc
as described above), then all you have to do is run:
rails new blog
The template will perform the following steps:
- Generate your application files and directories
- Create the development and test databases
- Commit everything to git
- Push the project to the remote git repository you specified
Add the --javascript vite
option to the rails new
command to get started with Vite! Vite is an easy to use alternative to Webpack(er), and much more powerful than the standard import map and css/jsbundling-rails options that are built into Rails.
- Frontend code (JS, CSS, images) will be placed in
app/frontend/
- Run
yarn start
to start the development server with hot reloading - SCSS will be used for styles (the
--css
option will be ignored)
If you don't specify --javascript vite
, then this template will use the standard Rails 7 behavior.
- Core
- active_type – for building simple and effective form/service objects
- sidekiq – Redis-based job queue implementation for Active Job
- Configuration
- dotenv – for local configuration
- Style
- Pico.css - a great-looking default stylesheet
- Utilities
- annotate – auto-generates schema documentation
- amazing_print – try
ap
instead ofputs
- rubocop – enforces Ruby code style
- erblint – applies rubocop rules within html.erb files
- Security
- brakeman and bundler-audit – detect security vulnerabilities
- Testing
- shoulda – shortcuts for common ActiveRecord tests
I like to use Postmark for transactional email, and so I've included the postmark-rails gem and configured it in environments/production.rb
. Make sure to sign up for a Postmark account to get an API key, or switch to your own preferred email provider before deploying your app.
- A much-improved
bin/setup
script - Log rotation so that development and test Rails logs don’t grow out of control
This project works by hooking into the standard Rails application templates system, with some caveats. The entry point is the template.rb file in the root of this repository.
Normally, Rails only allows a single file to be specified as an application template (i.e. using the -m <URL>
option). To work around this limitation, the first step this template performs is a git clone
of the mattbrictson/rails-template
repository to a local temporary directory.
This temporary directory is then added to the source_paths
of the Rails generator system, allowing all of its ERb templates and files to be referenced when the application template script is evaluated.
Rails generators are very lightly documented; what you’ll find is that most of the heavy lifting is done by Thor. The most common methods used by this template are Thor’s copy_file
, template
, and gsub_file
. You can dig into the well-organized and well-documented Thor source code to learn more.
