Installation
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'Usage
When using with wicked_pdf
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
})When using with pdf_kit or wisepdf
No extra configuration is needed. But please make sure you are not re-configuring the binary path again in their initializer files.
When using with other gems
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')
