Backend Integration

Todo

• Am I designing Backend? Or Just FE?

• API

  • Already written? Writing together with BE? Proposing?

  • Protocols: Sockets? REST? GraphQL? GRPC? Mix of each (REST for one time info, Sockets for Stock Prices)

• Error Handling

  • Retry Mechanism?

  • Messaging to the user

• Long Async Requests

  • Ex: Buy operation that may take 1+ minutes, chunked buy (buy shares as they become available)

  • Push messaging when operation is complete, email, think about this flow Multi Day operations - clearing of funds (prob email)

• Interaction with BE

  • Something like OpenAPI/Swagger to sync on documentation/API contract

  • Generating TypeScript Types from OpenAPI

  • Are we synching API versions between releases?

  • Make sure FE is released at same time as corresponding BE Major releases.

  • Minor releases? Breaking API releases?

  • How do we make sure nothing breaks as BE changes?

  • Integration testing strategy

  • Postman
