# Stacks Configuration

## Key Paths
- Core package: `storage/framework/core/config/src/`
- Configuration directory: `config/`
- Defaults: `storage/framework/core/config/src/defaults.ts`
- Overrides: `storage/framework/core/config/src/overrides.ts`

## Config API

```typescript
import { config, getConfig } from '@stacksjs/config'

config.app.name       // 'Stacks'
config.database       // full database config
config.auth           // auth config
getConfig()           // returns full StacksOptions
```

## Individual Config Exports

```typescript
import { ai, analytics, app, auth, cache, cloud, cli, database, dns, docs, email, errors, git, hashing, library, logging, notification, payment, ports, queue, realtime, security, saas, searchEngine, services, filesystems, team, ui } from '@stacksjs/config'
```

## Config Builder Functions

```typescript
import { defineApp, defineDatabase, defineCache, defineEmail } from '@stacksjs/config'

// Used in config files:
export default defineApp({
  name: 'My App',
  env: 'production',
  url: 'https://myapp.com'
}) satisfies AppConfig
```

All builders: `defineApp`, `defineCache`, `defineCdn`, `defineChat`, `defineCli`, `defineDatabase`, `defineDependencies`, `defineDns`, `defineEmailConfig`, `defineEmail`, `defineGit`, `defineHashing`, `defineLibrary`, `defineNotification`, `definePayment`, `defineQueue`, `defineSearchEngine`, `defineSecurity`, `defineServices`, `defineSms`, `defineFilesystems`, `defineUi`, `defineModel`, `defineEvents`

## Helper Functions
- `determineAppEnv(): 'dev' | 'stage' | 'prod' | string`
- `localUrl(): string` — local development URL

## Default Values (from defaults.ts)
- App name: `'Stacks'`
- Cache driver: `'memory'`
- Database: SQLite at `database/stacks.sqlite`
- Hashing: bcrypt, 12 rounds

- Ports: frontend 3000, backend 3001, admin 3002, api 3008

## Gotchas
- Config files are TypeScript with `satisfies` for type checking
- All configs support environment variable overrides via `env.*`
- Framework provides defaults — user overrides in `~/config/*.ts`
- Two duplicate file pairs: `file-systems.ts`/`filesystems.ts` and `query-builder.ts`/`qb.ts`
- Config changes may require dev server restart
- The `services.ts` file contains API keys for AWS, Stripe, Slack, Discord, OpenAI, Anthropic, etc.
- Lazy loading is used in config to avoid circular dependencies
