- 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
