What is @aws-sdk/credential-provider-process?
The @aws-sdk/credential-provider-process package is part of the AWS SDK for JavaScript (v3) and is used to load AWS credentials from a process specified in the shared AWS config and credentials files. This is useful for scenarios where you want to source credentials from an external process, which can be a custom credential provider or a token service.
What are @aws-sdk/credential-provider-process's main functionalities?
Loading credentials from a process
This feature allows you to load AWS credentials by executing a process defined in your AWS config file. The credentials returned by the process are then used to authenticate AWS SDK clients.
const { fromProcess } = require('@aws-sdk/credential-provider-process');
const credentials = fromProcess();
// Use credentials with an AWS SDK client
const client = new SomeAwsClient({ credentials });
Other packages similar to @aws-sdk/credential-provider-process
@aws-sdk/credential-provider-ini
This package is similar to @aws-sdk/credential-provider-process in that it is also used to load AWS credentials, but it does so from the AWS shared configuration file (typically located at ~/.aws/credentials). It does not execute an external process to obtain credentials.
@aws-sdk/credential-provider-cognito-identity
This package provides a way to retrieve AWS credentials by using Amazon Cognito Identity. It is different from @aws-sdk/credential-provider-process as it specifically targets Cognito for authentication rather than executing a custom process.
@aws-sdk/credential-provider-web-identity
This package is designed to retrieve AWS credentials from web identity token files, which is useful for workloads running on EKS or using OIDC identity providers. Unlike @aws-sdk/credential-provider-process, it does not involve running a separate process to obtain credentials.
@aws-sdk/credential-provider-sso
This package allows users to retrieve AWS credentials using AWS Single Sign-On (SSO). It differs from @aws-sdk/credential-provider-process by focusing on SSO as the credential source rather than a custom process.
