Configuration System

1// Configuration loading priority:
2// 1. Environment Variables (highest)
3// 2. Configuration File (moro.config.js/ts)  
4// 3. Schema Defaults (lowest)
5
6// Example: Database configuration
7// 1. DATABASE_URL env var = "postgresql://prod-server/db"
8// 2. moro.config.js = { database: { url: "postgresql://localhost/dev" } }
9// 3. Default = { database: { url: "sqlite://memory" } }
10// 
11// Result: Uses "postgresql://prod-server/db" from env var
12

16// Configuration is automatically loaded and merged

18// Access configuration
19console.log(app.config.database.url); // "postgresql://prod-server/db"
20console.log(app.config.server.port);  // From PORT env var or config file
