If you've uploaded a file to Heroku, only to find that it's vanished, you're not alone. When you deploy an application to Heroku, your app's code and dependencies are packaged into containers.
These containers are referred to as "dynos." Dynos have ephemeral filesystems and restart at least once a day. What does this mean for your app?
Any files that aren't part of your app's slug disappear when a dyno is replaced or restarted. Heroku's ephemeral filesystem is not designed for permanent file storage. We get it. It's frustrating.
Nope! Setting up S3 can be a lengthy, painful process. You have to create and configure a bucket, set up IAM credentials, set your bucket permissions and CORS policies.
Not to mention the work you have to do in your app - set up ENV variables, build out pre-signed upload URLS, and configure direct uploads via javascript. Wouldn't you rather spend your time and money on your app?
Simple File Upload uses direct uploads. What does that mean? Files are uploaded directly to S3 from your user's browser without passing through your app. This offloads the storage of static files from your app to the cloud.
Basically, you don't need to worry about Heroku's ephemeral filesystem. You can feel confident that your files are safe and secure with us.
Add the javascript snippet to the 'head' of your app.

Copy the provided javascript snippet to the 'head' of your app.
Create a hidden input with class `simple-file-upload`.
When your user uploads a file, it is immediately added to the cloud. A URL that links to that file is returned via a javascript event. It is also put in the value parameter of the hidden input. Save the 'value' parameter to your database.
View or download the uploaded file via the returned URL. If the file is an image, you can view it with a standard image tag.
