--- title: Configuration --- # Configuration We currently use two gems for configuring the application: - [ENVied](https://github.com/eval/envied) - [rails-settings-cached](https://github.com/huacnlee/rails-settings-cached) ## ENVied This gem is primarily used for configuring environment variables related to credentials and third party services. Examples: - `REDIS_URL` - `FASTLY_API_KEY` - `STRIPE_SECRET_KEY` Settings managed via ENVied can be found in [`Envfile`](https://github.com/thepracticaldev/dev.to/blob/master/Envfile) (see [Configuring Environment Variables](../getting-started/config-env.md)) and viewed at `/internal/config` (see [Accessing the admin panel](./admin.md)): ![Screenshot of env variable admin interface](https://user-images.githubusercontent.com/47985/73627243-67d41f80-467e-11ea-9121-221275ff8a89.png) ## rails-settings-cached We use this gem for managing settings used within the app's business logic. Examples: - `main_social_image` - `rate_limit_follow_count_daily` - `suggested_tags` These settings can be accessed via the [`SiteConfig`](https://github.com/thepracticaldev/dev.to/blob/master/app/models/site_config.rb) object and viewed / modified via `/internal/config` (see [Accessing the admin panel](./admin.md)). ![Screenshot of site configuration admin interface](https://user-images.githubusercontent.com/47985/73627238-6276d500-467e-11ea-8724-afb703f056bc.png)
