A URI wrapper that can parse out information about an S3 URI

Shamelessly adapted from https://github.com/aws/aws-sdk-java/blob/master/aws-java-sdk-s3/src/main/java/com/amazonaws/services/s3/AmazonS3URI.java

with notable exceptions:

• it doesn't parse version
• There is no preprocessing on given url string (you have to encode and replace special characters yourself if needed)
• For a valid S3 uri, region is never null but will default to us-east-1

const AmazonS3URI = require('amazon-s3-uri')

try {
  const uri = 'https://bucket.s3-aws-region.amazonaws.com/key'
  const { region, bucket, key } = AmazonS3URI(uri)
} catch((err) => {
  console.warn(`${uri} is not a valid S3 uri`) // should not happen because `uri` is valid in that example
})
