Manifester

A simple tool for fetching digested asset names at runtime (generated by mix phx.digest).

Implemented as a GenServer so it caches the manifest in memory.

Installation

Add to your mix.exs:

def deps do
  [
    {:manifester, "~> 1.0"}
  ]
end

If you're not using application inference, then add :manifester to your applications list.

Usage

Add the Manifester GenServer to you supervision tree, ideally at the top:

# Define workers and child supervisors to be supervised
children = [
  Manifester, # or worker(Manifester, [])
  # Repo, Endpoint...
]

and set your application name in config.exs:

config :manifester, otp_app: :myapp

Replace :myapp with your application name.

Now you're good to go!

Manifester assumes there is a cache_manifest.json generated in ./priv/static/ (which is default in Phoenix). If one is available, you can grab the digested asset name like so:

iex> Manifester.get("js/app.js")
"js/app-53ddc50a336555354d6b3d18b76d8af6.js"

You can use it to generate full URLs when using a CDN or for something else.
