File storage

Never commit large files to your Git repository. This will slow down all deployments and may make your project undeployable.

Your Shiny application may use large CSVs, JPEGs, PNGs, etc. Large binaries or large CSVs should be stored in Amazon S3 or in a database.

Heroku allows you to provision addons for your app, including databases like PostgreSQL or S3 buckets for asset storage.

Explore the add-ons Heroku offers.

For storing images, we suggest using Bucketeer.

Most add-ons when provisioned add environment variables to your Shiny application which contain the credentials and paths to access these add-ons from your code.

Please start with the lowest tier of each add-on you're using. If you need a larger database, S3 bucket, or other add-on, contact support to discuss options. E-mail [e-mail].
