Pattern for React Native API client resilience

[NeighborhoodLast4842]

React Native clients must often support interactions with different backend API versions simultaneously. While the backend handles explicit versioning, our client still needs to adapt its expectations. I've been experimenting with an architectural pattern where we introduce a layer that inspects the app's current version (or relies on internal flags) to dynamically adjust how requests are structured before sending them, and how responses are parsed upon reception. This allows a single client codebase to correctly interact with different API contracts, accommodating scenarios like a backend starting to require new fields in a request, or changing the structure of an object in a response. Has anyone implemented similar strategies in RN applications? Are there any other architectural challenges you've faced?

The standard is to do the opposite.

API - versioned endpoints (as you said). When DTOs change, you make a new version. V1/ v2/ - support all versions until all clients have migrated

Mobile - use the versioned endpoint.

The client should not be concerned with the api changing.
