## Overview

**Part of the Infra layer in the systemprompt.io architecture.**

This crate provides configuration management for the systemprompt.io platform:

- **YAML Configuration Loading**: Loads and merges base and environment-specific YAML files
- **Variable Resolution**: Resolves `${VAR_NAME}` and `${VAR_NAME:-default}` patterns
- **Secrets Management**: Loads `.env.secrets` files into environment
- **Validation**: Validates configuration completeness, URL formats, and environment-specific rules
- **File Generation**: Writes `.env` files for deployment

## File Structure

```

## Modules

### `manager.rs`
Core configuration management functionality:
- `ConfigManager::new(project_root)` - Initialize with project path
- `ConfigManager::generate_config(environment)` - Load and merge YAML configs
- Variable resolution with environment variable fallback
- Secrets file loading

### `schema_validation.rs`
Generic schema validation utilities:
- `validate_config<T>()` - Validate YAML against typed schema
- `validate_yaml_file()` - Parse and validate YAML syntax
- `generate_schema<T>()` - Generate JSON schema from types
- `build_validate_configs()` - Build-time validation for build.rs

### `types.rs`
Configuration type definitions:
- `DeployEnvironment` - Enum: Local, DockerDev, Production
- `DeploymentConfig` - Raw YAML configuration container
- `EnvironmentConfig` - Resolved environment variables

### `validator.rs`
Configuration validation:
- `ConfigValidator::validate()` - Run all validation checks
- `ValidationReport` - Collect errors and warnings
- Checks: unresolved variables, required variables, URL formats, port values

### `writer.rs`
Configuration file output:
- `ConfigWriter::write_env_file()` - Write standard .env file
- `ConfigWriter::write_web_env_file()` - Write VITE_* variables for web builds

## Public API

```rust
use systemprompt_config::{
    ConfigManager,
    ConfigValidator,
    DeployEnvironment,
    EnvironmentConfig,
    ValidationReport,
    validate_config,

};
```
