Grunt plugin for logging web page size

Heads up! This grunt task needs phantomjs to be installed!

This grunt task is able to summarize the asset size of a single web site page. Additionally it can track how much data transferred after the site has finished loading.

Options

• url
  target url, what needs to be downloaded and measured. It could be an enitre website or just a file from the web
• timeout
  timeout after the website has loaded. With setting this value you can measure the additional downloads your side does (like loading facebook like button or ads)
• reportPath
  report file output. It's going to be a JSON file with summarized and grouped information about the assets of the target website
• append
  set to true, if you would like to keep history of the reports
• historyLength
  maximum history length

Install

npm install git+ssh://[email protected]:tiborbotos/grunt-websize.git#master --save-dev
