This is a Heroku buildpack for vendoring the ImageMagick with WebP and HEIF support binaries into your project.
This buildpack works with BOTH Heroku stack heroku-20
and heroku-22
.
Add this buildpack to your app:
heroku buildpacks:add https://github.com/drnic/heroku-buildpack-imagemagick-webp -i 1 -a <app name>
And add it into your app.json
:
"buildpacks": [
{
"url": "https://github.com/drnic/heroku-buildpack-imagemagick-webp"
},
{
"url": "heroku/ruby"
}
],
See folder test/sample_app
for an example app and instructions for deploying it to heroku-22
or heroku-20
stacks.
When you use this buildpack it unpacks a pre-built build/imagemagick.tar.gz
file into your Heroku application's /./vendor
folder and sets up the relevant environment variables.
If you were to run a Heroku bash
session you can investigate the dependencies:
$ heroku run -a <appname> bash
~ $ convert -version
