# Appsignal.Phoenix

AppSignal's Phoenix instrumentation instruments calls to Phoenix applications
to gain performance insights and error reporting.

## Installation

To install `Appsignal.Phoenix` into your Phoenix application, first add
`:appsignal_phoenix` to your project's dependencies:

``` elixir
defp deps do
  {:appsignal_phoenix, "~> 2.0"},
end
```

After that, follow the [installation instructions for Appsignal for
Elixir](https://docs.appsignal.com/elixir/installation/).

Finally, `use Appsignal.Phoenix.View` in the `view/0` function in your app's
web module.

``` elixir
defmodule AppsignalPhoenixExampleWeb do
  # ...

  def view do
    quote do
      use Phoenix.View,
        root: "lib/appsignal_phoenix_example_web/templates",
        namespace: AppsignalPhoenixExampleWeb

      use Appsignal.Phoenix.View

      # Import convenience functions from controllers
      import Phoenix.Controller, only: [get_flash: 1, get_flash: 2, view_module: 1]

      # Include shared imports and aliases for views
      unquote(view_helpers())
    end
  end

  # ...
end
```
