I am trying to use pageres(https://github.com/sindresorhus/pageres) module to take screenshots of my website in different resolutions.
It works fine when I provide the URL and the size in command line but it doesn't work when I have my urls in a text file. It takes a screenshot of only the last URL in the file. I use the following command to run pageres:
pageres 640x768 < urls.txt
URLs in the text file are newline separated so they look like this:
http://www.yahoo.com
http://www.msn.com
http://www.apple.com
So it basically takes a screenshot of only apple.com and throws the error below for each of the screenshot above it.
The error I get is:
TypeError: 'undefined' is not an object <evaluating 'options.windowSize.width'>
and the file it points to is webshot.phantom.js line 13.
Am I running the command incorrectly or something? I use it the way it is mentioned on their site.
Thank you for your help.
