@takazudo/zfb-slugify

Standalone, zero-dependency heading-anchor slug utilities used by zfb. The package exports only slugify and SlugAllocator.

npm install @takazudo/zfb-slugify

import { SlugAllocator, slugify } from "@takazudo/zfb-slugify";

const allocator = new SlugAllocator("hierarchical");
const slug = allocator.allocate(2, slugify("Hello World")); // "hello-world"

The output matches zfb's Rust implementation through the shared fixture at crates/zfb-content/tests/fixtures/slugify-parity.json. The existing @takazudo/zfb/slugify export remains available for compatibility.

SlugAllocator accepts "flat" (the default) or "hierarchical"; call reset() between documents to clear deduplication and ancestor state.
