Express middleware that informs if request originates from a Google Bot or a Google Crawler
npm install express-is-googlecrawlerVery fast Express middleware that informs if request originates from a Google Bot or a Google Crawler.
Instead of making a new DNS request for every incoming request or checking the HTTP Header User-Agent which is not reliable, this middleware stores in-memory all known IP ranges coming from Google bots and crawlers, for very fast middleware processing.
