Exfile

Build Status

File upload handling in Elixir and Plug. Inspired heavily by Refile. If you use Ruby, check Refile out. I like it. A lot. 👍

Requires Elixir ~> 1.2.0. At this point, it is only tested against the most recent version of Elixir.

In very heavy development. Expect things to break. I’ll release 1.0 when it’s ready and I have it in a production environment.

Storage Adapters

Exfile, like Refile, supports pluggable storage adapters. Exfile ships with a filesystem-backed storage adapter.

  • exfile-memory — a memory-backed (ETS) storage adapter. This is usually only useful as a cache.
  • exfile-b2 — storage adapter for Backblaze B2.

File Processors

Exfile supports pluggable file processors / filters. If you’re working with images, exfile-imagemagick is recommended.

Installation

  1. Add exfile to your list of dependencies in mix.exs:

    def deps do
      [{:exfile, "~> 0.1.0"}]
    end
  2. Ensure exfile is started before your application:

    def application do
      [applications: [:exfile]]
    end
  3. Mount the Exfile routes in your router.

Phoenix

defmodule MyApp.Router do
  use MyApp.Web, :router

  foward "/attachments", Exfile.Router
  ...

Plug

defmodule MyApp.Router do
  use Plug.Router

  forward "/attachments", to: Exfile.Router
  ...

Configuration

In config.exs:

config :exfile, Exfile,
  secret: "secret string to generate the token used to authenticate requests",
  backends: %{
    "store" => configuration for a persistent store,
    "cache" => configuration for an ephemeral cache
  }

See lib/exfile/config.ex for defaults.
