capture-phantomjs

Capture screenshots using phantomjs.

Example

Capture a 1024x768 screenshot of twitter.com:

const capture = require('capture-phantomjs')
const fs = require('fs')

capture({
  url: 'https://twitter.com/',
  width: 1024,
  height: 768
}).then(screenshot => {
  fs.writeFileSync(`${__dirname}/example.png`, screenshot)
  console.log('open example.png')
})

API

screenshot({ url, width = 1024, height = 768, wait = 0, format = 'png', clip = true, cookies = [], ignoreSSLErrors = false, SSLCertificatesPath, SSLProtocol })

Capture a screenshot of url, returns a Promise which resolves with a buffer.

Options:

• url Page url
• width Viewport width
• height Viewport height
• wait Time in ms to wait after the page finished loading all initial resources
• format File format (png, jpg, gif)
• clip Cut the image to exact dimensions, removing the fold
• cookies Array of cookie objects, see below
• ignoreSSLErrors ignore SSL errors
• SSLCertificatesPath path for PhantomJS to look for SSL certificates
• SSLProtocol Supported protocols: sslv3, sslv2, tlsv1, any

Cookie format

The cookie format is this:

{
  name : 'valid-cookie-name',             // required
  value : 'valid-cookie-value',           // required
  domain : 'the-domain.com',              // required
  path : '/',
  httponly : true,
  secure : false,
  expires : (new Date()).getTime() + 3600 // expires in 1 hour
}
