# Default config

## What is defaultConfig?

defaultConfig is an object you can register with your Plugin to make sure that your plugin will have some default config value when a user install/update your plugin in Dashboard

```jsx
import DashboardPlugin from 'Dashboard/plugin'

const Plugin = new DashboardPlugin('@plugin_bundle')

const registerPlugin = () => {
    const { Application } = require('@components/Application')
    
    Plugin.register({
        application: Application,

        defaultConfig: {
            applicationKey: 'xxxx-xx-xxxxx-x-xxx'
        }
    })
}

registerPlugin()

export {
    Plugin
}
```

The object keys should be the ref keys of your config field.

In our example 👆🏽we registered a default config object with a key `applicationKey` that means in the Settings component, the ref who has the same key `applicationKey` will share the same value and it will be assigned as a default value for that ref

```jsx
import { Plugin } from '@root'

const GUI = Plugin.GUI

class Settings extends Plugin.settings {
    plugin() {
        return (
            <div>
                <GUI.ConfigInput
                    name={'Application key'}
                    ref={refs => this.handleRefs(refs, 'applicationKey')}
                />
            </div>
        )
    }
}
```

{% hint style="info" %}
If a plugin is already installed, and you added a new key to the defaultConfig object, Dashboard will add the new key to the config automatically, once the plugin is updated
{% endhint %}

{% hint style="info" %}
If a plugin is already installed, and you removed a key from the defaultConfig object, Dashboard won't remove any keys or value from the config.
