What is the alternative for the getRegion(V2) in V3

[rddimon]

Hi there,

In the serverless-domain-manager we use getRegion function for getting the default region which is available in the AWS SDK V2

We would like to upgrade the AWS SDK to V3 but don't see an alternative in V3.

We went through the credential-providers and thought about using the fromNodeProviderChain but haven't found a solution for us

Do we have a possibility of getting the region based on the AWS creds?

I found an alternative by myself. The credential-providers was the wrong way.
I went through the AWS client's sources and found the loadConfig for the region from the @aws-sdk/node-config-provider

The solution which works for me is:

import {loadConfig} from "@aws-sdk/node-config-provider";
import {NODE_REGION_CONFIG_FILE_OPTIONS, NODE_REGION_CONFIG_OPTIONS} from "@aws-sdk/config-resolver";

const currentRegion = await loadConfig(NODE_REGION_CONFIG_OPTIONS, NODE_REGION_CONFIG_FILE_OPTIONS)();

Thanks for this suggestion @rddimon, worked great!

If you're using the latest versions of the AWS Node SDK, the imports should use the smithy namespace:

import { loadConfig } from "@smithy/node-config-provider";
import { NODE_REGION_CONFIG_FILE_OPTIONS, NODE_REGION_CONFIG_OPTIONS } from "@smithy/config-resolver";

const currentRegion = await loadConfig(NODE_REGION_CONFIG_OPTIONS, NODE_REGION_CONFIG_FILE_OPTIONS)();
