If your Rails apps are anything like mine, one of the slowest parts of your deployment is waiting for asset pipeline precompilation. It's sometimes so slow, it's painful. So I went searching for some solutions. turbo-sprockets helped, but it's not a silver bullet. This gem isn't a silver bullet either, but it can help. Capistrano Local Precompile takes a different approach. It builds your assets locally and rsync's them to your web server(s).

Add capistrano-local-precompile to your Gemfile:

group :development do
  # Capistrano v2 should use '~> 0.0.5'
  # Capistrano v3 should use '~> 1.0.0'
  # Capistrano v3.8+ should use '~> 1.1.3'
  gem 'capistrano-local-precompile', '~> 1.1.3', require: false
end

Then add the following line to your Capfile:

require 'capistrano/local_precompile'

Remove the following line from your Capfile:

require 'capistrano/rails/assets'

Here's the full set of configurable options:

set :precompile_env             # default: fetch(:rails_env) || 'production'
set :assets_dir                 # default: "public/assets"
set :rsync_cmd                  # default: "rsync -av --delete"

This gem is derived from gists by uhlenbrock and keighl.

Pull requests welcome: fork, make a topic branch, commit (squash when possible) with tests and I'll happily consider.
