Migrating from v2.0 RCs

See the CHANGELOG for specific breaking changes from each RC. If upgrading from RC3, no additional changes are required.

Migrating from v1.6

Update your mix.exs dependencies.

[
  {:pigeon, "~> 2.0"} # Change this
  {:kadadbra, ~> 0.6.0} # Remove this
]

Update configuration of your push workers.

Pigeon push workers are now started under your application supervision tree instead of Pigeon.

Using APNS as an example, if you have a default push worker configured like this:

config :pigeon, :apns,
  apns_default: %{
    cert: "cert.pem",
    key: "key_unencrypted.pem",
    mode: :dev
  }

Remove the config and instead define a push worker like this:

# lib/your_app/apns.ex

defmodule YourApp.APNS do
  use Pigeon.Dispatcher, otp_app: :your_app
end

# config.exs

config :your_app, YourApp.APNS,
  adapter: Pigeon.APNS,
  cert: File.read!("cert.pem"),
  key: File.read!("key_unencrypted.pem"),
  mode: :dev

And add it to your supervision tree.

defmodule YourApp.Application do
  @moduledoc false

  use Application

  @doc false
  def start(_type, _args) do
    children = [
      YourApp.APNS
    ]
    opts = [strategy: :one_for_one, name: YourApp.Supervisor]
    Supervisor.start_link(children, opts)
  end
end

Configuration of the worker can now be passed directly if desired.

defmodule YourApp.Application do
  @moduledoc false

  use Application

  @doc false
  def start(_type, _args) do
    children = [
      {YourApp.APNS, apns_opts()}
    ]
    opts = [strategy: :one_for_one, name: YourApp.Supervisor]
    Supervisor.start_link(children, opts)
  end

  defp apns_opts do
    [
      adapter: Pigeon.APNS,
      cert: File.read!("cert.pem"),
      key: File.read!("key_unencrypted.pem"),
      mode: :dev
    ]
  end
end

And that's it! See the rest of this guide for other breaking changes specific to your push type.

Breaking Changes for ADM

No addtional changes required apart from the configuration above.

Breaking Changes for APNS

:certfile and :keyfile are no longer valid options for APNS configurations. Instead, read the file before loading (e.g. cert: File.read!("cert.pem")) (#183)

Breaking Changes for FCM

FCM's legacy API, used by Pigeon v1.6, has been decommissioned. To upgrade, add the legacy adapter to your mix.exs and follow worker setup instructions.

def deps do
  [
    {:pigeon_legacy_fcm, "~> 0.2.0"}
  ]
end

Rename all instances of Pigeon.FCM in your project to Pigeon.LegacyFCM. For example, Pigeon.FCM.Notification becomes Pigeon.LegacyFCM.Notification.

Once renamed, your project should now compile again.

Upgrade to the new FCM v1 API. Follow the instructions in Pigeon.FCM to set up a new push worker and update your Pigeon FCM notifications accordingly.
