Error Handling

When the server returns an error for a call, the client throws a RpcError with { code, name, message }.

Examples of sources:

• Non-HTTP errors → normalized to code 500
• Nest HttpException → code/status and message
• Network or invalid JSON parsing → RpcError.fromFetchError / fromInvalidJson

Handle errors per-call:

try {
  await rpc.user.queries.getUser({ id: 'missing' });
} catch (e) {
  if (e instanceof RpcError) {
    console.error(e.code, e.name, e.message);
  }
}
