This buildpack installs chromedriver (the Selenium driver for Chrome) in a Heroku slug.

This buildpack only installs the chromedriver binary. To use Selenium with Chrome on Heroku, you'll also need Chrome. We suggest one of these buildpacks:

  • heroku-buildpack-google-chrome to run Chrome with the --headless flag
    • Make sure you've installed heroku-buildpack-google-chrome BEFORE heroku-buildpack-chromedriver, so it can install the latest supported chromedriver for the verison of Chrome installed previously.
  • heroku-buildpack-xvfb-google-chrome to run Chrome against a virtual window server

Configuring the downloaded version of chromedriver.

By default, this buildpack will download the latest release, which is provided by Google.

If you've installed heroku-buildpack-google-chrome before this buildpack, it will download the latest supported chromedriver which has the same build version of the Chrome installed previously. - Here's the rule of the version number of Google Chrome: https://www.chromium.org/developers/version-numbers - Here's the rule of version selection implemented in this buildpack: http://chromedriver.chromium.org/downloads/version-selection - This only works for stable version and beta version of Chrome as describe in this document.

You can control the specific version by setting the CHROMEDRIVER_VERSION environment variable to an explicit version e.g. 2.39.

Releasing a new version
