## Configurations

This plugin use [del](https://www.npmjs.com/package/del) under the hood, so you can easily pass `del options` to this plugin.

```typescript
export interface CleanOptions {
  /**
   * file clean patterns (passed to `del`)
   *
   * @default: []
   */
  patterns?: string | string[];

  /**
   * file clean patterns(in onStart only) (passed to `del`)
   *
   * @default: []
   */
  cleanOnStartPatterns?: string | string[];

  /**
   * file clean patterns(in onEnd only) (passed to `del`)
   *
   * @default: []
   */
  cleanOnEndPatterns?: string | string[];

  /**
   * use dry-run mode to see what's going to happen
   *
   * this option will enable verbose option automatically
   *
   * @default: false
   */
  dryRun?: boolean;

  /**
   * extra options passed to `del`
   *
   * @default {}
   */
  options?: DelOptions;

  /**
   * execute clean sync or async (use `del` or `del.sync` for cleaning up)
   *
   * @default: true
   */
  sync?: boolean;

  /**
   * do cleaning in start / end / both
   * maybe in some strange cases you will need it ? :P
   *
   * @default: "start"
   */
  cleanOn?: 'start' | 'end' | 'both';

  /**
   * enable verbose logging to see what's happening
   *
   * @default false
   */
  verbose?: boolean;
}
