IsBot

Detect bots/crawlers/spiders using the user agent string.

Using a list downloaded from https://user-agents.net, the regexes in this package hit a 90% detection rate.
If nothing matches, it also checks if the user agent is present in the list.

Usage

import "github.com/stephenafamo/isbot"

func main() {
    userAgent := "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/98.0.0.0 Safari/537.36 Chrome-Lighthouse"
    isBot := isbot.Check(userAgent)
    if isBot {
        // do something
    }
}
