What configuration options does the slugify function accept?

The slugify function accepts the following configuration options in an options object:

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

   • Specifies the character(s) used to separate words in the slug [readme.md:L51-L80]

2. lowercase (boolean, default: true)

   • Controls whether the slug is converted to lowercase [readme.md:L51-L80]

3. decamelize (boolean, default: true)

   • Converts camelCase to separate words (e.g., fooBar → foo bar) [readme.md]

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

   • Allows you to define custom character replacements that run before other transformations [readme.md]

5. preserveLeadingUnderscore (boolean, default: false)

   • Preserves a leading underscore if the string starts with one [readme.md]

6. preserveTrailingDash (boolean, default: false)

   • Preserves a trailing dash if the string ends with one [index.js:L51-L80]

7. preserveCharacters (array, default: [])

   • Allows you to preserve specific characters that would normally be removed [test.js:L201-L230]

8. transliterate (boolean, default: true)

   • Controls whether Unicode characters are transliterated to ASCII; when false, non-ASCII characters are preserved [readme.md:L226-L255]

9. locale (string)

   • Specifies a locale for locale-specific transliteration behavior [test.js:L226-L255]

These options are merged with defaults in [index.js:L51-L80].
