Email a photo to snack at that domain and it'll get posted.
There's no metadata or attribution — post cool things and don't be a jerk.
You can run snacks on your own domain using Firebase, Google Cloud Platform, and Mailgun.
Mailgun is configured to call a webhook when emails are received.
That webhook (the receiveEmail function in this code base) downloads the attachments and processes them in another function (receivedAttachmentsPubSub).
EXIF data is stripped, and images are resized and compressed.
The processed images are stored in a Google Cloud Storage bucket, and an index is stored in Google Cloud Datastore.
The receiveEmail function generates a BSON Object Id to identify the post.
This id is used throughout the system as a consistent key across functions (logs can be correlated this way).
The original post (at its original resolution but without EXIF data) is archived separately to facilitate reprocessing without recompression.
Object Ids are naturally sorted by time which is convenient for sorting posts by when they were received.
The site is built with Next.js & React. Posts (a link to the image & its dimensions) are retrieved from the Datastore. The inital render ocurrs server side, and additional posts are fetched as the page scrolls.
