Amazon web services – How to use AWS SSO with AWS-SDK 2.x

In my Nodejs app, I have been using aws-sdk (2.x) to get S3 objects. Below code works pretty fine.

const AWS = require("aws-sdk");
S3 = new AWS.S3({
        accessKeyId: 'actual_accessKeyId',
        secretAccessKey: 'actual_secretAccessKey',
        region: 'region',
        signatureVersion: "v4",
});


const listBucketContent = (filePath, bucketName) => {
    const params = { Bucket: bucketName, Prefix: filePath };
    return S3.listObjects(params).promise();
};

However, as you can see above, I use hardcoded accesskey and secretaccesskey.

I actually don’t want to use accesskey and secretAccesskey.

I have AWS SSO configured in my machine which looks something like below,

[profile AWS-XXX]
sso_start_url = https://XXX.XXX.com/start/#
sso_region = XXXXX
sso_account_id = XXXXXXXXXX
sso_role_name = XXXAdministratorAccess
region = XXXX

I want to use SSO directly but don’t seem to find any way or articles to use it with aws-sdk.

So how can get S3 objects using AWS SSO?
