Question 1

How to override file settings with environment variables in GoLobby Config?

Accepted Answer

Use multiple feeders in order, with later feeders like Env overriding earlier ones such as Json; the README shows an example where Env feeder overrides DotEnv and Json values for fields like APP_PORT.

Question 2

GoLobby Config vs Viper: which should I use for Go configuration?

Accepted Answer

GoLobby Config is lighter and simpler with struct binding and live reload, while Viper offers more features like remote configuration and extensive format support. Choose GoLobby for straightforward, type-safe setups; Viper for complex, enterprise needs.

Question 3

How to set up live reload with SIGHUP signals?

Accepted Answer

Call the SetupListener() method on a Config instance with a fallback function; the README explains that it listens for SIGHUP and refreshes structs by calling Feed(), useful for updating config without redeployment.

Question 4

Can I use GoLobby Config with Kubernetes ConfigMaps?

Accepted Answer

Not directly; you would need to mount ConfigMaps as files or environment variables and use existing feeders like Json or Env, or implement a custom feeder to fetch from the Kubernetes API.

Question 5

How to handle nested structs and arrays in configuration?

Accepted Answer

Define nested structs in your configuration type and use appropriate tags; the README examples show structs with nested App fields and slices like IDs, which are automatically populated from feeders.

Question 6

What happens if a configuration value is missing in feeders?

Accepted Answer

Fields without values in feeders are ignored, as stated in the DotEnv and Env feeder sections; you can use the Setup() method for default values or error handling.
