# Presets

> Opinionated dev, prod, and json logging defaults

Use `preset` for one-line environment defaults. Explicit `config` fields always override the preset.

```ts theme={null}
import { Elysia } from 'elysia'
import logixlysia from 'logixlysia'

const app = new Elysia().use(
  logixlysia({
    preset: 'prod',
    config: {
      service: 'api',
      logFilePath: './logs/app.log'
    }
  })
)
```

## Available presets

| Preset | Startup banner | Pretty print | Context tree | `autoRedact` |
| ------ | -------------- | ------------ | ------------ | ------------ |
| `dev`  | Yes (banner)   | Yes          | Yes          | No           |
| `prod` | No             | No           | No           | Yes          |
| `json` | No             | No           | No           | No           |

## Override example

```ts theme={null}
logixlysia({
  preset: 'prod',
  config: {
    autoRedact: false,
    showStartupMessage: true
  }
})
```

You can also resolve options programmatically:

```ts theme={null}
import { resolveOptions } from 'logixlysia'

const options = resolveOptions({ preset: 'dev', config: { service: 'api' } })
```
