@answerfox/sitemap

Sitemap builder for the Answerfox SEO toolkit. Takes a list of paths, applies smart defaults inferred from path patterns, and returns a Next.js-compatible MetadataRoute.Sitemap.

v0.1.0. buildSitemap() and sitemapIndex() ship today with smart path-based defaults for priority and change frequency.

Install

pnpm add @answerfox/sitemap
# requires next >= 14

Usage

// app/sitemap.ts
import { buildSitemap } from '@answerfox/sitemap';

export default function sitemap() {
  return buildSitemap(
    [
      { path: '/' },
      { path: '/about' },
      { path: '/privacy' },
      { path: '/blog/launch' },
      { path: '/blog/post-1', lastModified: '2026-05-14' },
    ],
    { baseUrl: 'https://acme.com' },
  );
}

Smart defaults

Priority and changeFrequency are inferred from path patterns when you don't set them explicitly:

| Path pattern | priority | changeFrequency | |---|---|---| | / (home) | 1.0 | daily | | /blog/*, /news/*, /posts/* | 0.7 | weekly | | /docs/* | 0.6 | weekly | | /products/*, /pricing | 0.8 | weekly | | /about, /privacy, /terms, /contact, /faq | 0.3 | yearly | | Anything else | 0.5 | monthly |

Explicit priority or changeFrequency on a route always wins over inferred defaults.

Large sites (>50k URLs)

import { sitemapIndex } from '@answerfox/sitemap';

const index = sitemapIndex([
  { url: 'https://acme.com/sitemap-1.xml' },
  { url: 'https://acme.com/sitemap-2.xml', lastModified: new Date() },
]);
