Generate Go Structs from Config Object

Application configs have deep nesting: app settings, database credentials, feature flags. This example generates Go structs from a multi-level config structure so you can deserialize configuration files directly in your Go application.

What You Get

The tool produces:

How to Use

  1. The example loads with a sample application config in Go mode
  2. The nested structure shows how each config section gets its own struct type
  3. Copy the structs and paste them into your Go project
  4. Replace with your actual config JSON to generate structs for your project

Real-World Pattern

Go config libraries like Viper and Koanf work well with typed structs. Generate structs from your default config, then use json.Unmarshal or your config library’s decoder to populate them from JSON files, environment variables, or command-line flags.
