stream-s3-object

Usage

const AWS = require('aws-sdk')
const streamS3Object = require('stream-s3-object')
const s3 = new AWS.S3()

const getObjectRequest = s3.getObject({ /* whatever */ })
const { getHeader, headers, stream } = await streamS3Object(getObjectRequest)

Returned properties

The function returns an object containing the following properties asynchronously (i.e. as a Promise):

• getHeader(name: string): string?
  • Get the string value of the specified header name (or undefined), with case-insensitive matching
• headers: { [name: string]: string }
  • The exact headers object returned from the AWS SDK
• stream: stream.Readable
  • A readable stream representing the S3 object being retrieved, from s3.getObject(...).createReadStream()

Errors

The streamS3Object() call will throw a TypeError synchronously if the input doesn't appear to be a request object from the s3 getObject() method. The returned Promise will be rejected with the error value from any httpError event that is raised on the getObject() request.
