and wkhtmltoimage
will be available on /app/bin
,
you can just execute /app/bin/wkhtmltopdf ...
from your app.
Why another wkhtmltopdf buildpack
- None of the available buildpacks (made by the community - there's no official wkhtmltopdf buildpack by Heroku) uses wkhtmltopdf 12.4;
- Almost all of the available buildpacks downloads wkhtmltopdf from gna.org, but the service is not active anymore and will probably stop serving these files;
- Some of the buildpacks available set new environment vars instead of just
leaving the binary in some location. It increases the boot time since new
shell script files needed to be loaded (inside
.profile.d/
); - Most of the available buildpacks works only on
cedar-14
andheroku-16
stack -- andheroku-18
is the newest dyno stack.
This buildpack addresses the following issues:
- Uses wkhtmltopdf version 0.12.4
- Downloads wkhtmltopdf binaries from wkhtmltopdf.org
- Do not add new environment variables or shell scripts
- Tested on
cedar-14
,heroku-16
, andheroku-18
stack images
