for await (const url of crawlSite("https://github.com/", 500)) {
  links.push(url);
}

}

Documentation

The function crawlSite takes two parameters:

• site: Required. The site to crawl.
• timeout: Optional. The timeout between each link in miliseconds, default is 500.

There are examples of usage, above and below:

import { crawlSite } from "crawling";

// this should choose a random url

const links = [];
for (const url of await crawlSite("https://github.com/", 500)) {
  links.push(url);
}

console.log(shuffle(links)[0]);
