如何在 nodeJS 应用程序中使用 Amazon S3？

Question

I am trying to use Amazon S3 to upload/download some images and videos from inside my locally running NodeJS application. But when I search for that, there are tons of different code snippets and different credential management approaches and I am totally confused by that.

I created an IAM user and I have AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY, AWS_BUCKET_NAME in my .env file but I think it's not a good approach using .env file in my app and it's better I use temporary token credentials . But I don't know how?

What is the minimum secure code I can use to do that?

Read the AWS SDK for JavaScript V3 Developer Guide . There are many examples and yes - using creds is a standard practice.
