# Configuration

In order to run DemocracyOS, some config settings are needed. Default values are listed on `config/defaults.json`.

> _WARNING: Never change values at `config/defaults.json`, to edit any value use the methods listed below._

## Configuring

### Configuration Files

Environment specific options can be added using `config/{NODE_ENV}.json`. E.g.: If your `NODE_ENV` is `development` you can use `config/development.json`, the options there will override the ones at `config/defaults.json`.


You can generate configuration files using the command:

```
NODE_ENV=development node ./bin/dos-install --config
```

### Environment Variables

Environment Variables also can be used to override options (recommended for `production`). [Here's](https://help.ubuntu.com/community/EnvironmentVariables) explained how to manage environment variables on Linux/Mac.

* Var names should be `CONSTANT_CASE`.
  * e.g.: `mongoUrl` => `MONGO_URL`
  * Scoped variables e.g.: `notifications.url` => `NOTIFICATIONS_URL`
* `Arrays` should be strings separated by commas.
  * e.g.: `"staff": ["mail@eg.com", "a@c.m"]` => `STAFF="mail@eg.com,a@c.m"`
* `Boolean` values should be `true` or `false`.
  * e.g.: `"rssEnabled": false` => `RSS_ENABLED="false"`

> _For more info, the values are casted using [`lib/config/cast-string.js`](https://github.com/DemocracyOS/app/blob/development/lib/config/cast-string.js)._
