minimal-chrome-on-heroku

Getting Chrome up and running on Heroku!

This is a sister repo of jormon/minimal-chrome-on-heroku-xvfb which operates on the cedar-14 stack using xvfb.

I tried to keep the number of gems as minimal as possible, though I did include Thor for potential future uses with different configuration flags, etc.

Here are the rough needs to get this to work / notes:

  • There are some very hard-to-google configuration flags to set on your Chrome options, pay attention in the new_browser method if you're following along at home.
  • This uses watir for ease of scripting, but feel free to use raw Selenium.

Deployment

You can use the following button to deploy this to a test instance and check it out yourself!

Deploy

Use

Once you deploy, from your commandline, simply run the following command with heroku toolbelt:

$ heroku run "thor runner:website"

Downloads

The package also includes a test script to show how saving downloads from chrome can run. The thor task is runner:download, but I would advise invoking it like so:

$ heroku run bash
[heroku]$ bundle exec thor runner:download
[heroku]$ ls tmp/downloads # expect to see the rfc file here
