@aws-sdk/credential-provider-ini

What is @aws-sdk/credential-provider-ini?

The @aws-sdk/credential-provider-ini package is a module that allows Node.js developers to load AWS credentials from INI-formatted files, such as the ones created by the AWS CLI. This package is part of the AWS SDK for JavaScript (v3) and is used to retrieve AWS credentials from local configuration files, enabling developers to authenticate AWS SDK calls.

What are @aws-sdk/credential-provider-ini's main functionalities?

Loading credentials from a shared INI file

This feature allows developers to load AWS credentials from a shared INI file, typically located at `~/.aws/credentials`. The `fromIni` function reads the file and returns the credentials for the default profile or a specified profile.

const { fromIni } = require('@aws-sdk/credential-provider-ini');
const credentials = fromIni();

Specifying a custom profile

Developers can specify a custom profile to load credentials for a specific AWS account or role. This is useful when working with multiple AWS accounts or when different permissions are needed.

const { fromIni } = require('@aws-sdk/credential-provider-ini');
const credentials = fromIni({ profile: 'myCustomProfile' });

Assuming a role with MFA

This feature supports assuming an IAM role that requires Multi-Factor Authentication (MFA). The `mfaCodeProvider` is a function that returns the MFA code, which is then used to assume the role.

const { fromIni } = require('@aws-sdk/credential-provider-ini');
const credentials = fromIni({
  profile: 'myRoleProfile',
  mfaCodeProvider: async () => '123456', // Replace with actual MFA code provider
});

Other packages similar to @aws-sdk/credential-provider-ini

aws-sdk

The original AWS SDK for JavaScript (v2) includes credential loading capabilities similar to @aws-sdk/credential-provider-ini. It allows loading credentials from INI files, but it is part of a larger package rather than a modular approach taken by the newer AWS SDK (v3).

aws-profile-utils

This package provides utilities for working with AWS profiles stored in INI files. It offers similar functionality for loading credentials but is not officially maintained by AWS and may not have the same level of support or integration with the AWS SDK.

awscred

awscred is another npm package that can load AWS credentials from various sources, including INI files. It provides a simple interface for retrieving credentials but does not offer the modular, per-service approach of the AWS SDK (v3).
