# TowerDiscord

Error reporting to Discord.

A simple post-to-Discord reporter for Tower error handler that sends formatted error messages to a Discord channel via webhooks.

## Installation

The package can be installed by adding `tower_discord` to your list of dependencies in `mix.exs`:

```elixir
def deps do
  [
    {:tower_discord, "~> 0.1.0"}
  ]
end
```

## Usage

Register the reporter with Tower:

```elixir
# config/config.exs

config :tower, :reporters, [
  # along with any other possible reporters
  TowerDiscord
]
```

Add the Discord-specific configurations:

```elixir
# config/runtime.exs

config :tower_discord,
  webhook_url: System.get_env("TOWER_DISCORD_WEBHOOK_URL"),
  level: :error # Optional, defaults to :error
```

### Discord Webhook Setup

1. In your Discord server, go to Server Settings -> Integrations
2. Click on "Create Webhook"
3. Choose the channel where you want the error reports to appear
4. Copy the Webhook URL and use it in your configuration

The reporter will format error messages with:
- Error type and source location
