AWS credential provider that sources credentials from ~/.aws/credentials and ~/.aws/config

Last verified Sep 9, 2026 against @aws-sdk/credential-provider-ini@3.973.15.

@aws-sdk/credential-provider-ini ships CommonJS only. require("@aws-sdk/credential-provider-ini") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun. The package declares Node.js >=20.0.0. import "@aws-sdk/credential-provider-ini" also works because Node.js and Bun can import CommonJS from ES modules, but only the default export is guaranteed; named imports depend on Node's static analysis of the module.

It also declares a "module" field, so bundlers such as webpack, Vite and esbuild pick up an ESM build for tree-shaking.

## What to do

1. require("@aws-sdk/credential-provider-ini") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun. The package declares Node.js >=20.0.0.
2. From ES modules use the default import: import credentialProviderIni from "@aws-sdk/credential-provider-ini"; then destructure. Named imports only work when Node.js can statically detect the exports.
3. TypeScript: types are bundled; install nothing extra.
