Connect to AWS S3 API for static assets

[JSn1nj4]

Potential good starting point: Getting started with Amazon S3 storage in Laravel

The one I'm probably going with: https://laravel-news.com/uploading-files-laravel

Checklist

Not comprehensive, but should prevent storage issues

• Set up basic upload mechanism
• Set up disk environment var - expect local for dev, AWS S3 for prod
• Upload file to 'public' disk at first
• Call images folder in S3 'uploads/images' to separate from manual uploads
• Check if uploaded image already exists (file hash)
• If new....
  • Queue for permanent storage — run daily
  • Upload asset to permanent storage
  • Update asset URI, disk etc.
  • Remove old locally-stored file
• If existing...
  • Skip uploading as "new"
  • Attach existing
• After attachment, remove duplicates
• Add media management - will need controller
  • Create media library view
  • Look at full-size image
  • Prevent deletion if attached to anything
    • Check if latest attachment of anything only
  • Delete image if not attached
    • Clear all attachments first
  • On delete, queue storage cleanup
• After first S3 image access, cache for faster loading
  • Tell browser to cache?
  • Download to 'image-cache' directory or similar?
• Handle statically-linked assets separately
  • Store in separate folder 'assets'
• Periodically clean 'temp' storage
• Update IDE helpers
• Manually update any model fields necessary
• Update factories and seeders
• Update existing tests

See if this needs a queue too (e.g. from temp disk to permanent in AWS).

Might need to keep direct S3 uploads (e.g. for CSS and such) stored in public-facing bucket after all.
