This is a very simple example to upload a file to AWS S3 using NodeJS. This can easily be used in a Lambda function.

let AWS = require("aws-sdk");
var s3 = new AWS.S3();

async function upload_file()
	let aws_bucket = "my-bucket";
	let aws_key = "my-folder/filename.txt";
	let file_contents = "lets write this to the file";

	var params = {
        Body: file_contents,
        Bucket: aws_bucket,
        Key: aws_key


		//the aws sdk providers the "promise()" function that allows you to return a promise
		//since this is an async function, we can await the promise
        let s3_result = await s3.putObject(params).promise();
    catch (err)
