Verified traces

Basic slug — slugify({ text: "Hello World! This is a Test" }) → 2ms

{ "slug": "hello-world-this-is-a-test" }

Unicode folding — slugify({ text: "Ünïcödé Tëst — with dashes & special chars!" }) → 1ms

{ "slug": "unicode-test-with-dashes-special-chars" }

Custom separator — slugify({ text: "My Blog Post Title 2026", separator: "_" }) → 1ms

{ "slug": "my_blog_post_title_2026" }

Use cases

• Generate URL-safe routes from article/page titles
• Create filesystem-safe filenames from user input
• Build SEO-friendly slugs for CMS content
• Normalize identifiers across languages (diacritics → ASCII)
• Cap slug length for database varchar columns

Notes

• Unicode diacritics folded to ASCII (ü→u, é→e, ö→o)
• Non-alphanumeric chars stripped, separator runs collapsed
• max_length breaks at last separator (no truncated words)
• lowercase: false preserves original casing
