How to upload a file to Amazon S3 with Node.js?

To upload a file to Amazon S3 with Node.js, we call the putObject method.

For instance, we write

const AWS = require("aws-sdk");
AWS.config.update({
  accessKeyId: "accessKeyId",
  secretAccessKey: "secretAccessKey",
  region: "region",
});

const params = {
  Bucket: "yourBucketName",
  Key: "someUniqueKey",
  Body: "someFile",
};
try {
  const uploadPromise = await new AWS.S3().putObject(params).promise();
  console.log("Successfully uploaded data to bucket");
} catch (e) {
  console.log("Error uploading data: ", e);
}

to call update to connect to AWS.

Then we call putObject with an object with the Bucket, Key and Body to start the upload.

And then we use await to wait for the promise to finish running.
