Sitemap Generator

Travis David npm

Easily create XML sitemaps for your website.

Generates a sitemap by crawling your site. Uses streams to efficiently write the sitemap to your drive and runs asynchronously to avoid blocking the thread. Is cappable of creating multiple sitemaps if threshold is reached. Respects robots.txt and meta tags.

Table of contents


This module is available on npm.

$ npm install -S sitemap-generator

This module is running only with Node.js and is not meant to be used in the browser.

const SitemapGenerator = require('sitemap-generator');


const SitemapGenerator = require('sitemap-generator');
// create generator
const generator = SitemapGenerator('', {
  stripQuerystring: false
// register event listeners
generator.on('done', () => {
  // sitemaps created
// start the crawler

The crawler will fetch all folder URL pages and file types parsed by Google. If present the robots.txt will be taken into account and possible rules are applied for each URL to consider if it should be added to the sitemap. Also the crawler will not fetch URL's from a page if the robots meta tag with the value nofollow is present and ignore them completely if noindex rule is present. The crawler is able to apply the base value to found links.


The generator offers straightforward methods to start and stop it. You can also query some information about status and output.


Returns array of paths to generated sitemaps. Empty until the crawler is done.


Returns object with info about fetched URL's. Get's updated live during crawling process.

  added: 0,
  ignored: 0,
  errored: 0


Returns the status of the generator. Possible values are waiting, started, stopped and done.


Starts crawler asynchronously and writes sitemap to disk.


Stops the running crawler and halts the sitemap generation.


Add a URL to crawler's queue. Useful to help crawler fetch pages it can't find itself.


You can provide some options to alter the behaviour of the crawler.

var generator = SitemapGenerator('', {
  crawlerMaxDepth: 0,
  filepath: path.join(process.cwd(), 'sitemap.xml'),
  maxEntriesPerFile: 50000,
  stripQuerystring: true

Type: number
Default: 0

Type: number
Default: 50000

Google limits the maximum number of URLs in one sitemap to 50000. If this limit is reached the sitemap-generator creates another sitemap. A sitemap index file will be created as well.


Type: boolean
Default: true

Whether to treat URL's with query strings like as indiviual sites and add them to the sitemap.


Type: string
Default: Node/SitemapGenerator

Set the User Agent used by the crawler.


The Sitemap Generator emits several events which can be listened to.


Triggered when the crawler successfully added a resource to the sitemap. Passes the url as argument.

generator.on('add', (url) => {
  // log url


Triggered when the crawler finished and the sitemap is created. Provides statistics as first argument. Stats are the same as from getStats.

generator.on('done', (stats) => {
  // sitemaps created


Thrown if there was an error while fetching an URL. Passes an object with the http status code, a message and the url as argument.

generator.on('error', (error) => {
  // => { code: 404, message: 'Not found.', url: '' }


If an URL matches a disallow rule in the robots.txt file or meta robots noindex is present this event is triggered. The URL will not be added to the sitemap. Passes the ignored url as argument.

generator.on('ignore', (url) => {
  // log ignored url
