pssg

Description

pssg:

• stands for "pagespeed screengrab".
• is a node client for Google's "secret" screenshot API
• helps you rapidly generate thumbnails, like Urlbox (but free and lower quality) or PhantomJS (but faster and lower quality)

Usage

First, install pssg:

npm install pssg --save-dev

Then call download or base64:

var pssg = require('pssg');

var filename = 'yeezy_screengrab';
pssg.download('http://www.kanyewest.com', {
  dest: __dirname,
  filename: filename
}).then(function(file) {
  console.log('Saved to ' + file + '.');
});

pssg.base64('http://randallma.com')
  .then(function(b64) {
    console.log('Screenshot base64 snippet: ' + b64.substr(0, 20));
  });

That's it!
