MachineGun

HTTP client for Elixir. Based on Gun and Poolboy.

• Supports HTTP/1 and HTTP/2 with automatic detection;
• Maintains separate connection pool for each pool_group:host:port combination;
• Allows per-pool configuration;
• Drop-in replacement for HTTPoison.

Example

%MachineGun.Response{body: body, status_code: 200} =
  MachineGun.get!(
    "http://icanhazip.com",
    [{"accept", "text/plain"}],
    %{request_timeout: 5000, pool_group: :default})

(Options are included to show defaults and can be omitted.)

Configuration

config :machine_gun,
  # Default pool group
  default: %{
    pool_size: 4,         # Poolboy size [1]
    pool_max_overflow: 4, # Poolboy max_overflow [1]
    pool_timeout: 1000,
    conn_opts: %{}        # Gun connection options [2]
  }

(Configuration example shows defaults and can be omitted.)
