Now supports Heroku-20, and legacy versions Heroku-16 and Heroku-18.

Available for download at The Heroku Elements Marketplace. Search heroku-integrated-firefox-geckodriver on the official Heroku Elements Marketplace to access the buildpack.

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 master

Update 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>

import os
from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.firefox.firefox_binary import FirefoxBinary

def  load_driver():
	options = webdriver.FirefoxOptions()
	
	# enable trace level for debugging
	options.log.level = "trace"
options.add_argument("-remote-debugging-port=9224")
options.add_argument("-headless")
options.add_argument("-disable-gpu")
options.add_argument("-no-sandbox")

binary = FirefoxBinary(os.environ.get('FIREFOX_BIN'))

firefox_driver = webdriver.Firefox(
	firefox_binary=binary,
	executable_path=os.environ.get('GECKODRIVER_PATH'),
	options=options)

return firefox_driver

def  start():
	driver = load_driver()
	driver.get("https://www.google.com/")
	print(driver.title)
	driver.close()
if  name == "main":
	start()

NOTE: Make sure to add a requirements.txt file with relevant packages, and add the following entry to your Procfile:

worker: python app.py

require  'selenium-webdriver'

options = Selenium::WebDriver::Firefox::Options.new
options.add_argument('--remote-debugging-port=9222')
options.add_argument('--headless')
options.add_argument('--disable-gpu')
options.add_argument('--no-sandbox')
Selenium::WebDriver::Firefox::Binary.path=ENV['FIREFOX_BIN']
Selenium::WebDriver::Firefox::Service.driver_path=ENV['GECKODRIVER_PATH']
use argument :debug instead of :info for detailed logs in case of an error
Selenium::WebDriver.logger.level = :info 
driver = Selenium::WebDriver.for :firefox, options: options
driver.get "https://www.google.com"
puts  "#{driver.title}"
driver.quit

A minimalist Gemfile

source "https://rubygems.org"
gem 'selenium-webdriver', '3.142.7'

and Gemfile.lock file

NOTE: Run heroku run bash from your local machine to test your script. Execute command ruby app.rb via bash to see result.

try {
	await  driver.get('https://www.google.com/');
	console.log(await  driver.getTitle());
}
catch(err) {
	console.log(err.message);
}
finally {
	await  driver.quit();
}

NOTE: Make sure to add a package.json file with relevant packages, and add the following entry to your Procfile:

worker: node app.js
