S3DirectUpload

Pre-signed S3 upload helper for client-side multipart POSTs in Elixir.

See:

Browser-Based Upload using HTTP POST (Using AWS Signature Version 4)

Task 3: Calculate the Signature for AWS Signature Version 4

Installation

S3DirectUpload can be installed by adding s3_direct_upload to your list of dependencies in mix.exs and then running mix deps.get:

def deps do
  [{:s3_direct_upload, "~> 0.1.0"}]
end

This module expects three application configuration settings for the AWS access and secret keys and the S3 bucket name. You may also supply an AWS region (the default if you do not is us-east-1). Here is an example configuration that reads these from environment variables. Add your own configuration to config.exs.

config :s3_direct_upload,
  aws_access_key: System.get_env("AWS_ACCESS_KEY_ID"),
  aws_secret_key: System.get_env("AWS_SECRET_ACCESS_KEY"),
  aws_s3_bucket: System.get_env("AWS_S3_BUCKET"),
  aws_region: System.get_env("AWS_REGION")
