Backend Integration


  • 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
