# Fast

Build _faster_.

My grab-bag of utilities that I tend to want, but don't want to reimplement for every application I build.

## Installation

If [available in Hex](, the package can be installed
by adding `fast` to your list of dependencies in `mix.exs`:

def deps do
    {:fast, "~> 0.3.0"}

Documentation can be generated with [ExDoc](
and published on [HexDocs]( Once published, the docs can
be found at <>.

## Publishing

Update `mix.exs` with a version number.

Run `mix hex.publish`.

## Incorporating into a new app

### `Fast.Application.Ready` & `Fast.Plug.Ready`

GenServer that tracks whether an application is ready for traffic (for use with `Fast.Plug.Ready`).

1. Add `Fast.Application.Ready` as the last child in `application.ex`:

# lib/myapp/application.ex

defmodule MyApp.Application do
  use Application

  def start(_type, _args) do
    children = [
-    ]
+    ] ++ [{Fast.Application.Ready, otp_app: :my_app}]

    opts = [strategy: :one_for_one, name: MyApp.Supervisor]
    Supervisor.start_link(children, opts)

2. Add `Fast.Plug.Ready` to `lib/myapp_web/endpoint.ex`:

plug Fast.Plug.Ready, otp_app: :myapp, path: "/readyz"
