wkhtmltopdf-heroku

Provides a wkhtmltopdf binary for Heroku Ubuntu 18.04/20.04 LTS environment.

Experimental support for Heroku Stack-22 (Ubuntu 22 with OpenSSL 3.0) is also available via version 2.12.6.1.pre.jammy.

Preconfigures pdfkit, wicked_pdf, and wisepdf to use this binary if they are loaded.

In your Gemfile:

For Heroku Stack 18/20 (Ubuntu 18.04/20.04 LTS)

  gem 'wkhtmltopdf-heroku', '2.12.6.0'

Experimental support for Heroku Stack-22 (Ubuntu 22.04 LTS Jammy)

  gem 'wkhtmltopdf-heroku', '2.12.6.1.pre.jammy'

Since wicked_pdf overwrites its config hash in the initializer, you will need to update it to make sure its exe_path is configured correctly.

If you don't need any extra configurations, you can simply remove the initializer. Or you can change it to:

WickedPdf.config ||= {}
WickedPdf.config.merge!({
  # your extra configurations here
})

No extra configuration is needed. But please make sure you are not re-configuring the binary path again in their initializer files.

You will need to configure the path manually. You can get the path to the executable by using this: Gem.bin_path('wkhtmltopdf-heroku', 'wkhtmltopdf-linux-amd64')

0.12.6.0 Ubuntu Focal AMD64
