Documentation for PPlusFireStore.

This module is responsible for initializing the service that will manage access tokens to Google Firestore with the access credentials configured for your Firestore repository module.

By default, the service responsible for fetching the access token is Goth, but you can configure another access token fetching service through the :token_fetcher key in your repository configuration.

Goth uses the configured access credentials to fetch the access token and cache it. When requested, the service retrieves the access token from the cache and checks if it is still valid. If the access token is not in the cache or has expired, the service will fetch a new access token.

Usage

Define a repository module that implements the PPlusFireStore.Repo interface.

defmodule MyFireStoreRepo do
  use PPlusFireStore.Repo, otp_app: :my_app
end

Configure the repository module with Google Firestore credentials and add it to your supervision tree.

defmodule MyApp.Application do
  use Application

  @impl true
  def start(_type, _args) do
    children = [
      {PPlusFireStore, [MyFireStoreRepo]}
    ]

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

You can have more than one configured repository module, just add more repository modules to the list of modules.

children = [
  {PPlusFireStore, [MyFireStoreRepo, MyOtherFireStoreRepo]}
]
