# Manifester [](https://hex.pm/packages/manifester) [](https://hexdocs.pm/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`:
```elixir
def deps do
[
{:manifester, "~> 1.0"}
]
end
```
If you're not using [application inference](https://elixir-lang.org/blog/2017/01/05/elixir-v1-4-0-released/#application-inference), then add `:manifester` to your `applications` list.
## Usage
Add the `Manifester` GenServer to you supervision tree, ideally at the top:
```elixir
# Define workers and child supervisors to be supervised
children = [
Manifester, # or worker(Manifester, [])
# Repo, Endpoint...
]
```
and set your application name in `config.exs`:
```elixir
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:
```elixir
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.
