Additional Notes

• appy is made as a package for your application to import without the need to install any additional binary
• appy glues the great packages to provide best productivity in developing Go web application
• appy comes with 2 build types:
  • debug - when the code is NOT running within the binary
  • release - when the code is running within the binary
• appy follows 12factor via APPY_ENV environment variable:
  • by default, it is development
  • when APPY_ENV=staging is set, the config file is configs/.env.staging
  • utilise configs/.env.<APPY_ENV> to support multiple environments deployment
