Error Handling (v1)

This documents the old v1 API. See Getting Started for the current version.

Procedure (RPC) errors

Thrown errors are not serialized back to the client. The client call may reject due to RPC timeout.

Recommended pattern

// Server — return a typed result
.handle(({ input }) => {
  if (!isValid(input)) {
    return { ok: false as const, error: "VALIDATION_FAILED" as const };
  }
  return { ok: true as const };
})

// Client
const res = await client.doSomething(/* ... */);
if (!res.ok) console.error(res.error);

Connection errors

client.onError((err) => {
  console.error("Socket error:", err);
});
