What are @aws-sdk/node-config-provider's main functionalities?
Load Configuration from Environment Variables

const config = fromEnv();
console.log(config);
Load Configuration from Shared Config Files
This feature enables loading configuration settings from shared AWS config files, typically located in the user's home directory. This is useful for managing multiple profiles and settings in a centralized manner.
const { fromSharedConfigFiles } = require('@aws-sdk/node-config-provider');
const config = fromSharedConfigFiles();
console.log(config);
Load Configuration from a Custom Source
This feature allows you to load configuration settings from a custom source, such as hardcoded values or a custom configuration file. This provides flexibility in how you manage and load your AWS configuration settings.
const { fromStatic } = require('@aws-sdk/node-config-provider');
const config = fromStatic({ region: 'us-west-2', credentials: { accessKeyId: 'AKIA...', secretAccessKey: 'SECRET...' } });
console.log(config);
