review

Get screenshots of all your running sites in different resolutions!

Updating large and possibly responsively designed sites can be a hassle. You never know whether your change breakes anything on the other end of your sitemap, or in a certain resolution, except if have a look at every individual page...in every resolution you care about.

The idea of review is not to test everything (and visual testing is hard) but rather use the human mind's excellent ability to quickly scan information and filter out what you need, i.e. what is broken.

This screenshot is from review-host, which hosts multiple reviews in one server.

review()
  .title('My Review')
  .sites({ google : 'http://google.com/' })
  .resolutions(['1280x1024', '1900x1600', '800x600'])
  .cache({
    dir : __dirname + '/cache/',
    expires : 60
  })
  .cookie({
    name : 'cookie monster',
    value : 'i eat them!',
    domain : 'google.com'
  })
  .listen(4000)

For Windows users: Windows doesn't like single quote marks (thanks @jdarling for pointing this out) so you can only use double quotes:

review --sites="{\"google\":\"http://google.com\",\"facebook\":\"http://facebook.com\"}" --resolutions="[\"1280x1024\", \"1900x1600\", \"800x600\"]"

API

review()

Returns an http / express request handler.

review#title(title)

Display title in the review. Defaults to Review.

review#sites(sites | fn)

Either pass an object with titles as keys and urls as values, or a Function that fetches the sites to be displayed. This way, on every page load that list is refreshed and you can e.g. display all sites present in your sitemap.

review.sites(function (cb) {
  request('http://my.si/temap', function (err, res) {
    if (err) return cb(err)
    cb(null, format(res))
  })
})

See example/sites

review#resolutions(["WxH", "WxH", ...])

Configure the resolutions to use for screenshots. Defaults to ["1200x800"]

review#wait(x)

PhantomJS will wait for x milliseconds after loading the page before it takes the screenshot, so you can make sure your page is completely loaded. Defaults to 0.

review#cache({ dir : 'directory', expires : 60 })

Cache rendered snapshots for expires seconds in dir.

PhatomJS will use this cookie when requesting all pages.

The cookie format is:

{
  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
}

review#cut(bool)

If bool is true then screenshots will be cut to the exact dimensions that you specified. Without this pages can be longer than your specified height.

review#listen(port)

Start the review server on port port.

Installation

There is no need to have phantomjs installed, it will be fetched together with review.

$ npm install -g review # for cli
$ npm install review    # for library
