Example 01: Basic Usage

The simplest possible confkit example demonstrating core concepts.

What This Shows

• Creating a configuration
• Adding a layer with values
• Getting values with GetValue (simple)
• Getting values with Get (with source info)
• Key normalization (dot, underscore, hyphen, case)

Running

go run main.go

Key Points

1. Layers - Configuration is organized in named layers
2. Key-Value - Simple string key-value storage
3. GetValue - Returns just the value and whether it was found
4. Get - Returns value, source key, layer name, and found status
5. Normalization - Different key formats resolve to the same value

Output

Application: MyApp
Port: 8080 (from layer 'defaults', key: server.port)

Key normalization test:
  server.host → localhost
  server_host → localhost
  server-host → localhost
  SERVER_HOST → localhost
  SERVER.HOST → localhost
