Buildpack heroku-integrated-firefox-geckodriver enables your application or client code - running in any high-level language such as Python, Ruby or Node.js - to access Firefox along with Geckodriver (the Selenium driver for Firefox) in a Heroku slug and enables the driver objects to perform automated operations defined in the source code.
Version compatibility as follows:
- Firefox v82.0.3
- Geckodriver v0.28.0
To install and integrate the buildpack with your application running on Heroku's dyno:
$ heroku create --buildpack https://github.com/pyronlaboratory/heroku-integrated-firefox-geckodriver
# or if your app is already created:
$ heroku buildpacks:add https://github.com/pyronlaboratory/heroku-integrated-firefox-geckodriver
$ git push heroku masterUpdate Heroku's environment variables to store the following path strings.
FIREFOX_BIN: /app/vendor/firefox/firefox
Alternatively, you can even use /app/vendor/firefox/firefox-bin
GECKODRIVER_PATH: /app/vendor/geckodriver/geckodriver
LD_LIBRARY_PATH: /usr/local/lib:/usr/lib:/lib:/app/vendor
PATH: /usr/local/bin:/usr/bin:/bin:/app/vendor/
These configuration variables can be updated via Heroku CLI as follows:
Executable command: heroku config:set <ENV_VARIABLE>=<ABSOLUTE_PATH>
$ heroku config:set FIREFOX_BIN=/app/vendor/firefox/firefox
