Hammer is a rate-limiter for Elixir, with pluggable storage backends.
This library is a plug helper, to easily add rate-limiting to Phoenix applications, or any Elixir system that uses plug.
Example:
# Allow ten uploads per 60 seconds
plug Hammer.Plug, [
rate_limit: {"video:upload", 60_000, 10},
by: {:session, :user_id}
] when action == :upload_video_file
def upload_video_file(conn, _opts) do
# ...
