Pantograph is Goldbely's image resizing and serving service powered by jimmynicol's image-resizer. It's configured to work with S3 and Heroku out of the box.
Simply create a new Heroku app, set the environment variables, and deploy.
You may need to add Heroku specific environment variables that are not included in the .env.example:
BUILDPACK_URL=https://github.com/ddollar/heroku-buildpack-multi
NODE_ENV=production
The app does not do any image caching at all. Because of this it is recommended to place your production app behind a CDN. We use AWS's CloudFront.
For using Pantograph with local development.
Clone the repo to your machine and then:
docker-compose upChange any settings in the docker-compose.yml file to suite your needs.
The .env has a IMAGE_404 variable that should be set as a path to an image relative to your base URL.
When using S3 the path is relative to the bucket root.
When using Local the path is relative to LOCAL_FILE_PATH.
Always make sure the IMAGE_404 is set as the plugin code isn't very fault tolerant to that not existing yet.
