The slugify function accepts the following configuration options:

1. separator [index.d.ts:L1-L18]

   • Type: string

   • Allows you to customize the character(s) used to separate words in the slug

2. lowercase [index.d.ts:L26-L40]

   • Type: boolean
   • Default: true
   • Controls whether the slug is converted to lowercase

3. decamelize [index.d.ts:L51-L62]

   • Type: boolean
   • Default: true
   • Converts camelCase to separate words (e.g., fooBar → foo bar)

4. customReplacements [index.d.ts:L51-L80]

   • Type: Array<string[]>
   • Default: [['&', ' and '], ['🦄', ' unicorn '], ['♥', ' love ']]
   • Allows you to define custom text replacements that run on the original string before other transformations

5. preserveLeadingUnderscore

   • Type: boolean
   • Default: false
   • Preserves leading underscores in the slug

6. preserveTrailingDash [readme.md:L176-L205]

   • Type: boolean

   • Preserves trailing dashes in the slug

7. preserveCharacters [readme.md:L176-L205]

   • Type: string[]

All these options are combined in the Options type definition [index.d.ts:L1-L30].
