The slowest part in a rails application is in the assets compiling. So let's throw it out! This gem adds a local build of assets and packs right on your machine and then uploads all the files to the server.

Add local-precompile to your Gemfile:

group :development do
  gem 'local_precompile', '~> 0.3.3', require: false
end

Remove any gems associated with assets, like:

gem 'capistrano-faster-assets'
gem 'quiet_assets'

Then add the following line to your Capfile:

require 'local_precompile/capistrano'

Remove the following line from your Capfile:

require 'capistrano/rails/assets'

Change webpacker compile options in config/webpacker.yml to false:

staging:
  compile: false

production:
  compile: false

Remove node modules folder from set :linked_dirs your config/deploy.rb.

Here's the full set of configurable options:

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

Capistrano supports dry run mode. In that case the rsync command will not actually be run but only shown in stdout:

cap production deploy --dry-run

This gem is based on another gem with the same functionality but improved capistrano-local-precompile.

In turn that gem is derived from gists by uhlenbrock and keighl.

So many thanks to this guys.

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