@routes/isbot

🕷 Express middleware to detect crawler requests: request.isbot

The middleware adds a getter to the request: isbot.

• ✅ Lazy processing: performs the check only if it's actually used
• ✅ Memoisation: Operation result is cached
• ✅ Quick and Simple: Only check if it's a known crawler, does not parse the user agent string to a complex object
• ✅ Customisable bot list

const isbot = require('@routes/isbot');

app.use(isbot);

app.get('/api', (request, response) => {
	if (request.isbot) {
		// do things
	}
	...

	response.sendStatus(200);
});
