@lacspace/slugify

Turn any text into a clean, SEO-friendly URL slug.

Transliterates common diacritics (é → e), strips the rest, collapses separators, truncates on word boundaries, and can guarantee uniqueness against existing slugs. Perfect for article/product URLs.

• ✂️ slugify() with lower / separator / maxLength / custom replace
• 🔢 uniqueSlug() — appends -2, -3… against a Set/array
• ⚡ Zero dependencies · 🌍 isomorphic · 📦 ESM + CJS · fully typed

Install

npm install @lacspace/slugify      # or pnpm add / yarn add / bun add

Usage

import { slugify, uniqueSlug } from "@lacspace/slugify";

slugify("Héllo, World! — 2026");            // "hello-world-2026"
slugify("StockYatra: Paper Trading");        // "stockyatra-paper-trading"
slugify("Über Café", { separator: "_" });    // "uber_cafe"
slugify("A very long article title here", { maxLength: 15 }); // "a-very-long" (word boundary)

uniqueSlug("Hello", new Set(["hello", "hello-2"])); // "hello-3"
