## Installation
Add pigeon and kadabra as `mix.exs` dependencies:
```elixir
def deps do
[
{:pigeon, "~> 1.6.0"},
{:kadabra, "~> 0.4.4"}
]
end
```
## Quickstart Guides
### Apple iOS (APNS)
1. Add a default worker config to your mix config. See [the detailed
docs](https://hexdocs.pm/pigeon/apns-apple-ios.html) for setting up your
certificate and key.
```elixir
config :pigeon, :apns,
apns_default: %{
cert: "cert.pem",
key: "key_unencrypted.pem",
mode: :dev
}
```
This config sets up a default connection to APNS servers. `cert` and
`key` can be any of the following:
- Static file path
- Full-text string of the file contents
- `{:my_app, "certs/cert.pem"}` (indicates path relative to the `priv`
folder of the given application)
Alternatively, you can use token based authentication:
```elixir
config :pigeon, :apns,
apns_default: %{
key: "AuthKey.p8",
key_identifier: "ABC1234567",
team_id: "DEF8901234",
mode: :dev
}
```
- `:key` - Created and downloaded via your developer account. Like `:cert`
this can be a file path, file contents string or tuple
- `:key_identifier` - The 10-character key identifier associated with
`:key`, obtained from your developer account
- `:team_id` - Your 10-character Team ID, obtained from your developer
account
2. Create a notification packet. **Note: Your push topic is generally the
app's bundle identifier.**
```elixir
iex> n = Pigeon.APNS.Notification.new("your message", "your device token", "your push topic (optional)")
```
3. Send the packet. Pushes are synchronous and return the notification with an
updated `:response` key.
```elixir
iex> Pigeon.APNS.push(n)
%Pigeon.APNS.Notification{device_token: "your device token",
expiration: nil, id: "963B9FDA-EA60-E869-AAB5-9C88C8E7396B",
payload: %{"aps" => %{"alert" => "your message"}}, response: :success,
topic: "your push topic"}
# Add an `:on_response` callback for async pushes.
iex> Pigeon.APNS.push(n, on_response: fn(x) -> IO.inspect(x) end)
:ok
```
Additional documentation: [APNS (Apple iOS)](https://hexdocs.pm/pigeon/apns-apple-ios.html)
### Android (FCM)
Looking for GCM? Try `v0.13` or earlier.
1. Add a default worker config to your mix config.
```elixir
config :pigeon, :fcm,
fcm_default: %{
key: "your_fcm_key_here"
}
```
2. Create a notification packet. FCM notifications support
```elixir
iex> msg = %{ "body" => "your message" }
iex> n = Pigeon.FCM.Notification.new("your device registration ID", msg)
```
3. Send the packet. Pushes are synchronous and return the notification with
updated `:status` and `:response` keys. If `:status` is success, `:response`
will contain a keyword list of individual registration ID responses.
```elixir
iex> Pigeon.FCM.push(n)
%Pigeon.FCM.Notification{message_id: "0:1512580747839227%8911a9178911a917",
payload: %{"notification" => %{"body" => "your message"}}, priority: :normal,
registration_id: "your device registration ID",
response: [success: "your device registration ID"],
status: :success}
# Add an `:on_response` callback for async pushes.
iex> Pigeon.FCM.push(n, on_response: fn(x) -> IO.inspect(x) end)
:ok
```
Additional documentation: [FCM (Android)](https://hexdocs.pm/pigeon/fcm-android.html)
### Amazon Android (ADM)
1. Add a default worker config to your mix config.
```elixir
config :pigeon, :adm,
adm_default: %{
client_id: "your_oauth2_client_id_here",
client_secret: "your_oauth2_client_secret_here"
}
```
2. Create a notification packet.
```elixir
iex> msg = %{ "body" => "your message" }
iex> n = Pigeon.ADM.Notification.new("your device registration ID", msg)
```
3. Send the packet.
```elixir
iex> Pigeon.ADM.push(n)
%Pigeon.ADM.Notification{consolidation_key: nil,
expires_after: 604800, md5: "M13RuG4uDWqajseQcCiyiw==",
payload: %{"data" => %{"body" => "your message"}},
registration_id: "your device registration ID",
response: :success, updated_registration_id: nil}
# Add an `:on_response` callback for async pushes.
iex> Pigeon.ADM.push(n, on_response: fn(x) -> IO.inspect(x) end)
:ok
```

## Startup Configuration of Push Workers
Workers may be specified at application startup by creating a module containing
functions that return zero or more configuration structures appropriate to the
push service being enabled.
Specify these in your `config.exs` as:
```elixir
config :pigeon, workers: [
{YourApp.Pigeon, :apns_config},
{YourApp.Pigeon, :fcm_config},
{YourApp.Pigeon, :adm_config}
]
```
These should be implemented as:
```elixir
defmodule YourApp.Pigeon do
@moduledoc false
@push_mode if(Mix.env() == :production, do: :prod, else: :dev)
def apns_config do
Pigeon.APNS.ConfigParser.parse(
key: System.get_env("APNS_KEY"),
key_identifier: System.get_env("APNS_KEY_ID"),
team_id: System.get_env("APNS_TEAM_ID"),
mode: @push_mode,
name: :apns_default
)
end
def fcm_config do
Pigeon.FCM.Config.new(name: :fcm_default, key: System.get_env("FCM_SERVER_KEY"))
end
end
```
If your startup configuration requires reading your configuration from a
database or using another dependency that needs a database, startup is a little
more complex.
1. Modify your `mix.exs` to _not_ start `pigeon` by default:
```elixir
def deps do
[
{:pigeon, "~> 1.3.1", runtime: false},
{:kadabra, "~> 0.4.4"},
{:ecto, "~> 2.0 or ~> 3.0"}
]
end
```
2. Modify `config.exs` to specify a single worker function:
```elixir
config :pigeon, workers: [{YourApp.Pigeon, :config}]
```
3. Modify your main application to start `pigeon` after your `Repo` has been
started under your application’s supervision tree:
```elixir
def start(_type, _args) do
children = [
YourApp.Repo,
]
opts = [strategy: :one_for_one, name: YourApp.Supervisor]
with {:ok, sup} <- Supervisor.start_link(children, opts),
{:ok, _} <- Application.ensure_all_started(:pigeon, :permanent) do
{:ok, sup}
end
end
```
4. Implement your database query as part of your Pigeon module:
```elixir
defmodule YourApp.Pigeon do
@moduledoc false
alias YourApp.{PushApplication, Repo}
def config_workers do
PushApplication
|> Repo.all()
|> Enum.map(&build_config/1)
end
defp build_config(%{type: "apns"} = config)
Pigeon.APNS.ConfigParser.parse(
key: config.key,
key_identifier: config.key_identifier,
team_id: config.team_id,
mode: config.mode,
name: Atom.to_string(config.name) # This is bad, but keep it simple!
)
end
defp build_config(%{type: "fcm"} = config) do
Pigeon.FCM.Config.new(
name: Atom.to_string(config.name),
key: config.key
)
end
end
```
