Sample Flask web app for taking web page screenshots using Selenium PhantomJS driver. Runs on Heroku.
Note: this is a very simple experiment. There are probably many better implementations out there.
See scrn.herokuapp.com for example.
This app uses heroku-buildpack-multi buildpack.
Pass the buildpack as param during app creation or configure it later using BUILDPACK_URL var.
heroku apps:create app-name --buildpack https://github.com/ddollar/heroku-buildpack-multi.git
heroku config:set BUILDPACK_URL=https://github.com/ddollar/heroku-buildpack-multi.git
Inspect the heroku config and make sure that the following vars are set (and add them if missing):
LD_LIBRARY_PATH: /usr/local/lib:/usr/lib:/lib:/app/vendor/phantomjs/lib
PATH: /usr/local/bin:/usr/bin:/bin:/app/vendor/phantomjs/bin
