Development Environment Performance Tips

This isn't s a small project. It's normal that you face a slow development environment (due to class reloading, assets, etc).

Slow Asset Compiling

If you're facing slow asset compiling, you can precompile all assets on dev environment, setting up:

  • the DEVELOPMENT_ASSETS_COMPRESS env variable to "true"
  • the DEVELOPMENT_ASSETS_DEBUG env variable to "false"
  • and running RAILS_ENV=development bundle exec rake assets:precompile command

Remember, if you run bundle exec rake assets:precompile without specifying the RAILS_ENV variable, it'll run against Rails' production environment, causing errors on the asset compilation process.
