Heroku Deployment

Heroku buildpacks

React on Rails requires both a ruby environment (for Rails) and a Node environment (for Webpack), so you will need to have Heroku use multiple buildpacks.

Assuming you have downloaded and installed the Heroku command-line utility and have initialized the app, you will need to tell Heroku to use both buildpacks via the command-line:

heroku buildpacks:set heroku/ruby
heroku buildpacks:add --index 1 heroku/nodejs

assets:precompile

Shakapacker webpack configuration

Shakapacker hooks up a new shakapacker:compile task to assets:precompile, which gets run whenever you run assets:precompile. If you are not using Sprockets, shakapacker:compile is automatically aliased to assets:precompile.

If you're using the standard shakacode/shakapacker configuration of webpack, then shakacode/shakapacker will automatically modify or create an assets:precompile task to build your assets.

Alternatively, you can specify config.build_production_command to have react_on_rails invoke a command for you during assets:precompile.

config.build_production_command = "RAILS_ENV=production NODE_ENV=production bin/shakapacker"

Consider Removing Shakapacker's clean task

If you are deploying on Heroku, then you don't need Shakapacker's clean task which might delete files that you need.
