What configuration options does the slugify function accept?

The slugify function accepts the following configuration options via an Options object [index.d.ts:L1-L200]:

1. separator (string, default: '-')

   • Character(s) to use between words in the slug [index.d.ts:L1-L16]

2. lowercase (boolean, default: true)

   • Makes the slug lowercase [index.d.ts:L18-L33]

3. decamelize (boolean, default: true)

   • Converts camelCase to separate words (e.g., fooBar → foo bar) [index.d.ts:L35-L52]

4. customReplacements (Array<string[]>, default: [['&', ' and '], ['🦄', ' unicorn '], ['♥', ' love ']])

   • Allows custom character/string replacements that run before other transformations [index.d.ts:L54-L79]

5. preserveLeadingUnderscore (boolean, default: false)

   • Preserves a leading underscore if the string starts with one [README excerpt]

6. preserveTrailingDash (boolean, default: false)

   • Preserves a trailing dash if the string ends with one [index.d.ts:L121-L135]

7. preserveCharacters (string[], default: [])

   • Specifies characters to preserve in the output (cannot contain the separator) [index.d.ts:L137-L155]

8. locale (string, default: undefined)

   • Sets the locale for language-specific transliteration [index.d.ts:L157-L172]

9. transliterate (boolean, default: true)

   • Controls whether Unicode characters are transliterated to ASCII or preserved [index.d.ts:L174-L200]

The function implementation at [index.js:L46-L111] shows how these options are merged with defaults and applied during the slugification process.
