Upload Process

1. Verification

• Request Verification

  • The file should be an image

• Check for GPS

  • We extract the EXIF data and check it for GPS keys.
    • If no GPS keys are found, a 500 error is thrown and the process is aborted.
  • We then test for empty "0/0" values, which we believe can be introduced when transferring images across devices.
    • If no GPS values are found, a 500 error is thrown with this information.

• Check For Duplicates

  • We check the dateTime the image was taken at.
  • The user will get an error if they try to upload the same photo twice.

2. Upload the Photo

• We use AWS S3 on production, DigitalOcean on staging, and public/local-uploads/ on development/testing environments.
• The photo is resized to 500 x 500 dimensions for the OpenLitterAI.
  • The photo is stored in a filesystem according to its creation date: year/month/day/fileHashName.jpg

3. Check For Locations

• Create New Locations
  • If a new location is created, we fire these events: NewCountryAdded, NewStateAdded, and NewCityAdded.
  • These need to move to after the Photo was created.

4. Update Leaderboards & XP.

• We need to move the Users XP to Redis.
• We need daily, weekly, monthly Leaderboards.

5. Dispatch Events & Notifications

• After everything is done, we should dispatch these last.
