prerender-bot-monitor

Simple prerender plugin for writing access logs based on prerender-access-log originally published by Andrei Demian.

So what's the difference?

This prerender plugin works absolutely the same way, with these little improvements:

• works with current version of prerender based on Headless Chrome
• there is a bonus pac.js log parsing script helping you extract particular bots from a given log file
• all original dependencies are updated and npm audited

How to use

In your local prerender project run:

npm install prerender-bot-monitor --save
or alternatively you can clone this repo and run npm install

Configuration

Then in the server.js that initializes the prerender:
server.use(require('prerender-bot-monitor'));

The plugin uses the morgan for creating logs and file-stream-rotator for managing file names.

  var server = prerender({
    botMonitor: {
        // Check out the file-stream-rotator docs for parameters
        fileStreamRotator: {
            filename: '/var/log/prerender/access-%DATE%.log',
            frequency: 'daily',
            date_format: 'YYYY-MM-DD',
            verbose: false
        },

        // Check out the morgan docs for the available formats
        morgan: {
            format: 'combined'
        }
    }
  });

pac.js log parsing script

This tool is located in utils/pac.js along with two test files.

Simple script which can extract access log records for particular bot. For your convenience I recommend to copy this to the folder where your access logs dwell.

Usage

$ node pac <file-name> [switches]

file-name - the full path to the access log file (thus this is convenient to copy pac.js to the log file folder)

Possible command line switches:

-g filters for Googlebot Desktop
-gm filters for Googlebot Mobile
-gi filters for Googlebot Image
-gv filters for Googlebot Video
-s filters for SeznamBot
-b filters for bingbot
-h or --help prints this help
--short prints short version
