Goth

A re-implementation of Goth.

Notable differences:

• Configurable HTTP client (with built-in support for Finch)

• Use JOSE package directly instead of going through Joken.

• Use persistent_term to avoid single-process bottleneck.

• Configure different servers for different tokens instead of global config.

• You add it to your own supervision tree.

• Simple built-in backoff.

On the flip side, we don't support everything Goth has, notably we:

• support only JSON credentials (and not the metadata service)

• support one scope per credentials

• haven't been around for more than 4 years!

Usage

Add Goth to your supervision tree:

credentials = "GOOGLE_APPLICATION_CREDENTIALS_JSON" |> System.fetch_env!() |> Jason.decode!()

children = [
  {Finch, name: MyApp.Finch},
  {Goth, name: MyApp.Goth, http_client: {Goth.HTTPClient.Finch, name: MyApp.Finch}, credentials: credentials},
  ...
]

Supervisor.start_link(children, ...)

And use it:

Goth.fetch(MyApp.Goth)
#=> {:ok, %Goth.Token{}}

Installation

Add goth to your list of dependencies in mix.exs:

def deps do
  [{:goth, github: "wojtekmach/goth"}]
end
