express-nobots

Keep Bots And Crawlers Away From Your Express App

This simple to integrate module uses the user-agent header to determine whether or not a request is made from a bot, and if so, either blocks it or tags the request.

Installation

npm install express-nobots --save

Usage

Make sure to include this as the first middleware!

Blocking Bots (sends 401 unauthorised):

var noBots = require('express-nobots');
 
....
 
app.use(noBots());
//or
app.use(noBots({block:true}));

Tagging Bots (this will set req.isBot to true if a bot makes a request):

var noBots = require('express-nobots');
 
....
 
app.use(noBots({block:false}));

Request from a bot with block set to false:

...
console.log(req.isBot);
//true
...
