Restored server with FlightControl

2024-01-04

Server Crashed. migrating to Fly.io... Because I wanted a Vercel-like experience for backends. However migrating is a pain... because originally I wrote everything as CF workers functions. Such a stress, app is getting delayed and delayed

  • There was a property in MSMessage of shouldExpire. The problem is that the recipient can override to keep the message, which we don't want.
  • Implemented Message Reading Functionality
  • I implemented proper loading view features, with fade-in and fade-out.

  • Refactored a lot of files

  • Linked the client side to
    • request server
    • pack it as MSMessage
    • send the message
    • dismiss the keyboard & request a compact presentation style
  • Pink Bubble?

Used Prisma, Prisma Accelerate, PlanetScale, and Cloudflare Workers to create a simple server for the Ganymede Table Structure. Prisma layer makes three requests to the DB per 1 request to the server, albeit it probably would hit the Prisma Accelerate Layer, we can later optimize it with this document.

  • It is possible to limit iMessage forwarding for iMessage Extensions
  • It is possible to mark the iMessage with LocalParticipantIdentifier
  • LocalParticipantIdentifier is different on all devices
  • The most straightforward way would be marking:
    • Set LocalParticipantIdentifier to true on reading (on the server)
    • Reject if LocalParticipantIdentifier is already true.
  • Problem: If the user deletes and reinstalls the app, LocalParticipantIdentifier changes. So the user can read unlimited times if the uninstall & reinstall
  • Mitigation: Assign UUID for each message. Each message will have LocalParticipantIdentifier + RemoteParticipantIdentifiers count as the maxRead. This will at least 'limit' the max read count.
  • Problem: on a Group Chat setting, a user can read unlimited times instead of another participant.
  • Solution: Sign in with Apple?!

In iOS 17, Shortcuts can send messages without confirmation. Can we use this for Send Separately or Ganymede?

  • Read notifications
  • Screenshot notifications
  • Broadcast
  • App Clip + Apple Login?
  • Therefore, we name it Project Ganymede. You can NEVER win Apple. It is the most massive system, just like Jupiter. Therefore, we choose to become a moon. The moon of Jupiter. And a moon can be bigger than planets. Ganymede is bigger than Mercury.

I finished some working prototypes. Some concerns: It seems like the transcript MSMessage is an immutable object. We might consider server approaches, such as KV storage.

I don't want to store any encrypted or decrypted messages on the server. So we can consider something as:

  • When sending a message
  • When reading the message
    • extract UUID and encrypted message
    • read KV with UUID and delete the DecryptKey if any necessary condition is met
    • once it expires, the user cannot read the message again

Considerations

  • How do you store different strategies (After 5 seconds? 10 seconds? 15 seconds?)
  • Group chats
  • Photo / Video Payload
  • Screenshot detections and notifications
