HTTPStream is a tiny, tiny package that wraps HTTP requests into a Stream so that you can manage data on the fly, without keeping everything in memory.

Downloading an image:

HTTPStream.get(large_image_url)
|> Stream.into(File.stream!("large_image.png"))
|> Stream.run()

Streaming multiple images into a ZIP archive (using zstream)

[
  Zstream.entry("a.png", HTTPStream.get(a_url))
  Zstream.entry("b.png", HTTPStream.get(b_url))
]
|> Zstream.zip()
|> Stream.into(File.stream!("archive.zip"))
|> Stream.run()

First, you need to add http_stream to your list of dependencies on mix.exs:

def deps do
  [
    {:http_stream, "~> 1.0.0"},

    # if using the Mint adapter:
    {:castore, "~> 0.1.7"},
    {:mint, "~> 1.1.0"}

    # if using the HTTPoison adapter:
    {:httpoison, "~> 1.7.0"}
  ]
end

HTTPStream comes with two adapters: Mint and HTTPoison. By default Mint is configured but you need to include it in your dependencies.

To use HTTPoison, set in your config/config.exs:

config :http_stream, adapter: HTTPStream.Adapter.HTTPoison

That's it! For more intricate API details, refer to the documentation.

If you want to setup the project for local development, you can just run the following commands.

git clone [email protected]:subvisual/http_stream.git
cd http_stream
bin/setup
