Send Rails exceptions to Discord via an incoming webhook

RailsDiscordNotifier is a lightweight gem that captures unhandled exceptions in your Rails application and delivers detailed error reports directly to a Discord channel via a configurable webhook. You own the codebase and can customize the format, embed fields, and delivery settings to suit your needs.

• Middleware-based interception of all uncaught exceptions
• Rich embed messages with exception class, message, backtrace, request method & URL, and timestamp
• Configurable via environment variables and initializer
• Safe error handling: notification failures are logged but don’t interrupt your app

Add the gem directly from RubyGems.org by including it in your Gemfile:

gem "rails_discord_notifier", "~> 0.1.0"

Then install:

bundle install

Or use Bundler:

bundle add rails_discord_notifier

Generate the default initializer in your Rails app:

rails generate rails_discord_notifier:install

In config/initializers/rails_discord_notifier.rb, configure your webhook and options:

RailsDiscordNotifier.configure do |config|
  # Discord webhook URL (required)
  config.webhook_url = ENV.fetch("DISCORD_WEBHOOK_URL")

  # Bot username (optional, defaults to ENV["ERROR_BOT_NAME"] or "Error Bot")
  config.username    = ENV.fetch("ERROR_BOT_NAME", "Error Bot")

  # Bot avatar URL (optional)
  # config.avatar_url = ENV.fetch("ERROR_BOT_AVATAR_URL", nil)
end

Ensure the middleware is loaded (added automatically by the Railtie).

Any uncaught exception in your controllers or middleware stack will now send an embed to Discord before re-raising.
