I am trying to configure the AWS JavaScript SDK for use with Node.js. I am trying to establish connectivity between a React app running locally, and a Lambda, using the @aws-sdk/client-lambda and @aws-sdk/credential-providers packages. I am following this AWS documentation to configure my Lambda client: https://docs.aws.amazon.com/sdk-for-javascript/v3/developer-guide/setting-credentials-node.html .
I am creating a session token using the AWS CLI, with the command: aws cli login -s, and then selecting my preferred IAM role. The output of this command is:
Assuming role arn:aws:iam::1234567890:role/12345-my-role-name as NAEAST\MyUserID on app-dev-12345-myorg (1234567890) in region us-east-1... According to the docs, I should be able to use the default provider chain to access this token that I just created:
AWS SDK for JavaScript V3 provides a default credential provider chain in Node.js, so you are not required to supply a credential provider explicitly. The default credential provider chain attempts to resolve the credentials from a variety of different sources in a given precedence, until a credential is returned from the one of the sources. You can find the credential provider chain for SDK for JavaScript V3 here.
I am assuming this default provider chain is the fromNodeProviderChain. The code they give to use this credential provider is:
import { fromNodeProviderChain } from "@aws-sdk/credential-providers"; // ES6 import // const { fromNodeProviderChain } = require("@aws-sdk/credential-providers") // CommonJS import const credentialProvider = fromNodeProviderChain({ //...any input of fromEnv(), fromSSO(), fromTokenFile(), fromIni(), // fromProcess(), fromInstanceMetadata(), fromContainerMetadata() // Optional. Custom STS client configurations overriding the default ones. clientConfig: { region }, }); I add this to my bare-bones React app, like so:
import { LambdaClient, InvokeCommand } from '@aws-sdk/client-lambda'; import { fromNodeProviderChain } from '@aws-sdk/credential-providers'; const HomePage = () => { const region = 'us-east-1'; const credentialProvider = fromNodeProviderChain({ //...any input of fromEnv(), fromSSO(), fromTokenFile(), fromIni(), // fromProcess(), fromInstanceMetadata(), fromContainerMetadata() // Optional. Custom STS client configurations overriding the default ones. clientConfig: { region }, }); const config = { region, credentials: credentialProvider }; const client = new LambdaClient(config); ... ... ... However, I get an error like this:
Uncaught SyntaxError: The requested module '/node_modules/.vite/deps/@aws-sdk_credential-providers.js?t=1708529564599&v=0778e0cf does not provide an export named 'fromNodeProviderChain' (Home.tsx:4:10) What is going on here? I am able to import the Lambda client using ES6 syntax, so that is not the issue. I am also able to import other credential providers from the @aws-sdk/credential-providers package, such as:
import { fromCognitoIdentity } from '@aws-sdk/credential-providers'; import { fromTemporaryCredentials } from '@aws-sdk/credential-providers'; // ES6 import These do not throw an import error. I would very much like to use fromNodeProviderChain because that seems by far the easiest to set up, and it should be able to grab my session token.
