`Phoenix.View` + `Swoosh`.
This module provides the ability to set the HTML and/or text body of an email by rendering templates.
## Installation
Add `:phoenix_swoosh` to your list of dependencies in `mix.exs`:
```elixir
def deps do
[
{:phoenix_swoosh, "~> 1.0"},
# without phoenix_html, phoenix_swoosh only works with plain text templates
# if you want to use HTML templates
# {:phoenix_html, "~> 3.0"},
]
end
```
You probably also want to install [`finch`](https://hex.pm/packages/finch),
[`hackney`](https://hex.pm/packages/hackney) or an HTTP client of your own choice,
if you are using a provider that `Swoosh` talks to via their HTTP API.
Or [`:gen_smtp`](https://hex.pm/packages/gen_smtp) if you are working with a provider
that only works through SMTP.
See `Swoosh` for more details.
## Usage
### 1. Classic setup
Setting up the templates:
```eex
# path_to/templates/user_notifier/welcome.html.eex
<div>
<h1>Welcome to Sample, <%= @name %>!</h1>
</div>
```
```elixir
# path_to/views/user_notifier_view.ex
defmodule Sample.UserNotifierView do
use Phoenix.View, root: "path_to/templates"
end
```
Passing values to templates:
```elixir
# path_to/notifiers/user_notifier.ex
defmodule Sample.UserNotifier do
use Phoenix.Swoosh, view: Sample.UserNotifierView
def welcome(user) do
new()
|> from("tony@stark.com")
|> to(user.email)
|> subject("Hello, Avengers!")
|> render_body("welcome.html", %{name: name})
end
end
```
Maybe with a layout:
```eex
# path_to/templates/layout/email.html.eex
<html>
<head>
<title><%= @email.subject %></title>
</head>
<body>
<%= @inner_content %>
</body>
</html>
```
```elixir
defmodule Sample.LayoutView do
use Phoenix.View, root: "path_to/templates"
end
```
```elixir
# path_to/notifiers/user_notifier.ex
defmodule Sample.UserNotifier do
use Phoenix.Swoosh,
view: Sample.NotifierView,
layout: {Sample.LayoutView, :email}
# ... same welcome ...
end
```
Layout can also be added/changed dynamically with `put_new_layout/2` and `put_layout/2`
### 2. Standalone setup
```eex
# path_to/templates/user_notifier/welcome.html.eex
<div>
<h1>Welcome to Sample, <%= @name %>!</h1>
</div>
```
```elixir
# path_to/notifiers/user_notifier.ex
defmodule Sample.UserNotifier do
use Phoenix.Swoosh,
template_root: "path_to/templates",
template_path: "user_notifier"
# ... same welcome ...
end
```
In this setup, the notifier module itself serves as the view module
`template_root`, `template_path` and `template_namespace`
will be passed to `Phoenix.View` as `root`, `path` and `namespace`.
Layout can be setup the same way as classic setup.
