import { isAIBot } from 'ua-parser-js/helpers';

const ahref = 'Mozilla/5.0 (compatible; AhrefsBot/7.0; +http://ahrefs.com/robot/)';
const firefox = 'Mozilla/5.0 (X11; Linux x86_64; rv:109.0) Gecko/20100101 Firefox/111.0';
const searchGPT = 'Mozilla/5.0 AppleWebKit/537.36 (KHTML, like Gecko); compatible; OAI-SearchBot/1.0; +https://openai.com/searchbot';

const botParser = new UAParser({ Bots });

console.log(isAIBot(botParser.setUA(ahref).getResult())); // false
console.log(isAIBot(botParser.setUA(firefox).getResult())); // false
console.log(isAIBot(botParser.setUA(searchGPT).getResult())); // true

import { isAIBot } from 'ua-parser-js/helpers';

console.log(isAIBot(req.headers['user-agent']));
