$ npm install -S advanced-sitemap-generator
This module is running only with Node.js and is not meant to be used in the browser.
`JavaScript
const SitemapGenerator = require('advanced-sitemap-generator');
// create generator
const generator = SitemapGenerator('http://example.com', {
stripQuerystring: false,
ignoreHreflang: true
});
// register event listeners
generator.on('done', () => {
// sitemaps created
});
// start the crawler
generator.start();
`
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 add URL's manually.
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.
There are a couple of options to adjust the sitemap output. In addition to the options beneath the options of the used crawler can be changed. For a complete list please check it's official documentation.
`JavaScript`
var generator = SitemapGenerator('http://example.com', {
ignoreHreflang: true,
maxDepth: 0,
filepath: path.join(process.cwd(), 'sitemap.xml'),
maxEntriesPerFile: 50000,
stripQuerystring: true,

Exclude Specific files or extensions from being crawled and been added to sitemap
Type: Array []

Exclude Specific URLs' patterns from being crawled and been added to sitemap
Type: HTTPAgent https.globalAgent

Type: boolean false
Default:
Whether to add a line to each URL in the sitemap, and fill it with today's date.
Type: number 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 true
Default:
Whether to treat URL's with query strings like http://www.example.com/?foo=bar as indiviual sites and add them to the sitemap.
Type: boolean true
Default:
Whether to deep crawl every page searching for hreflang attributes to add alternative links to the generated sitemap or not.
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.
`JavaScript`
generator.on('add', (url) => {
// log url
});
Triggered when the crawler finished and the sitemap is created.
`JavaScript`
generator.on('done', () => {
// 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.
`JavaScript`
generator.on('error', (error) => {
console.log(error);
// => { code: 404, message: 'Not found.', url: 'http://example.com/foo' }
});
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.
`JavaScript``
generator.on('ignore', (url) => {
// log ignored url
});
