A sitemap is a file that contains information about the pages, videos, and other files on your website, as well as their relationships. Search engines such as Google use this file to crawl your site more effectively.
By providing a sitemap, you can indicate to search engines which pages and files are important on your site, and also share useful details about them, such as when they were last updated and whether there are alternative language versions available.
In this guide, I'll walk you through the process of automating the creation of a sitemap using Node.js. The guide will cover the creation of both sitemap index and sitemaps, along with handling multi-language content. Furthermore, I will show you how to automate the entire process, resulting in a fully-automated Node.js server for sitemap generation.
