What is @aws-sdk/node-config-provider?

The @aws-sdk/node-config-provider package is part of the AWS SDK for JavaScript. It provides utilities for loading configuration settings for AWS SDK clients in Node.js environments. This package helps in managing configuration options such as credentials, region, and other settings required to interact with AWS services.

What are @aws-sdk/node-config-provider's main functionalities?

Load Configuration from Environment Variables

This feature allows you to load configuration settings directly from environment variables. This is useful for managing sensitive information like AWS credentials and region settings without hardcoding them in your application.

const { fromEnv } = require('@aws-sdk/node-config-provider');
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);
