shared/api

Wire-format DTOs shared between the backend API and frontend apiclient.

Rules

1. Create an api type when both sides encode/decode it

If the backend marshals a response and the frontend (or any other client) unmarshals it, define a named type here. No inline anonymous structs, no map[string]T literals on either side.

// Good
writeJSON(w, api.LastModifiedResponse{LastModifiedAt: lastModified})

var result api.LastModifiedResponse
utils.Decode(resp.Body, &result)

// Bad — fields can drift silently
writeJSON(w, map[string]time.Time{"last_modified_at": lastModified})

var result struct { LastModifiedAt time.Time `json:"last_modified_at"` }

2. Don't wrap domain types — decode them directly

If the response is a domain type (or a slice of one), serialize/deserialize it directly. An api type that only wraps a domain type adds indirection with no benefit.

// Good — domain type used directly on the wire
writeJSON(w, []domain.Message{...})

var messages []domain.Message
utils.Decode(resp.Body, &messages)

// Bad — pointless wrapper
type UserActivityResponse struct { Messages []domain.Message }

Trade-off: this couples the wire format to the domain model. If a domain type gains a sensitive internal field with JSON tags, it will be exposed. Add an api type if you need to diverge.

3. No response body when status is enough

Mutations that convey no information beyond success (e.g. delete, logout, revoke) return only an HTTP status code. No {"message": "done"} bodies.

// Good
w.WriteHeader(http.StatusOK)

// Bad
writeJSON(w, map[string]string{"message": "User blacklisted successfully"})
