Adding S3 Credentials for Node.js AWS SDK
My go-to method for gaining access to AWS using the Node.js tooling.
Long story short, it's Amazon — there are way too many ways to set credentials.
Though my preferred method is not the recommended way, I find that it plays well with setting other environment-based values for your application. That is by using environment variables.
The AWS SDK automatically looks for your credentials in environment variables. You can set the following values:
AWS_ACCESS_KEY_IDAWS_SECRET_ACCESS_KEY
Then it'll just work, like magic!
A big benefit to this approach is that you can have multiple projects on your machine and set these values contextually based on the project you're working with.
