@aws-sdk/region-config-resolver

Resolving region configuration

This feature allows the automatic resolution of the AWS region by checking environment variables, AWS configuration files, and other sources. It simplifies handling region-specific configurations in your application.

const { defaultRegionResolver } = require('@aws-sdk/region-config-resolver');

const region = defaultRegionResolver();
console.log(region);

Custom region resolution

This feature enables developers to define custom strategies for resolving the AWS region, such as prioritizing environment variables or specific profiles in shared configuration files. It provides flexibility in how regions are determined based on the application's needs.

const { fromEnv, fromSharedConfigFiles } = require('@aws-sdk/region-config-resolver');

const customRegion = fromEnv() || fromSharedConfigFiles({ profile: 'myProfile' });
console.log(customRegion);
