## Listening for events

```typescript
Client # on(eventChannel: string, handler: (payload: any) => void): EventSubscription
```

The `on` method allows you to listen for events from the Client, and in some cases from the configurator indirectly. The method accepts an [event channel](event-channels) string as its first argument, and a handler as its second.

## Requesting a configuration hash

```javascript
Client # getConfigurationHash(): Promise<string>
```

`getConfigurationHash` returns a promise that will in time resolve to a hash representing the currently active configuration of the SKIK Configurator.

A SKIK Configuration hash is a string representing a certain SKIK closet configuration. Such a hash can after retrieval be used to query for the relevant product data server-side (e.g. for adding items to cart) or simply to associate it as a 'favorite' of a certain user account. Hashes represent persisted, immutable SKIK closet configurations.

## Obtaining the IFrame element

```typescript
Client # frameElement(): HTMLIFrameElement
```

Returns the IFrame element object in which the configurator is loaded.

## Toggling auto-resizing of the IFrame container

```typescript
Client # enableAutoResize(): this
Client # disableAutoResize(): this
```

The methods `enableAutoResize` and `disableAutoResize` allow you to toggle auto-sizing of the frame container element at runtime.

## Toggling display of the language switch

```typescript
Client # showLocaleSwitch(): this
Client # hideLocaleSwitch(): this
```

You might want to control the language setting programatically depending on your application's state. The methods `showLocaleSwitch` and `hideLocaleSwitch` allow you to toggle the display of the language switch at runtime. Initial configuration for this setting can be given at [`Client` construction](static#constructor-options).

## Setting the language of the configurator

```typescript
Client # setLocale(locale: string): this
```

Sets the locale (language) of the configurator to given value, if the language is supported. Text contents of the configurator are updated in real-time. The given locale must be of type `string`: a language identifier in ISO 639-1 format. Currently supported languages:

- `"nl"` (Dutch)
- `"en"` (English)

## Getting an array of all product EAN codes

```typescript
Client # getEANCodes(): Promise<string[]>
```

Returns a promise that resolves to a string-array containing all EAN codes for products used by the configurator.

## Setting the prices for products

```typescript
Client # setProductPrices(prices: ProductPrices[]): Promise<boolean>
```

Stores given product prices, and then uses it to calculate / publish the total price of the current configuration.

## Setting custom article numbers for products

```typescript
Client # setArticleNumbers(articleNumbers: ArticleNumber[]): Promise<boolean>
```

Stores given article numbers, and uses them to identify products within the product-manifest modal, and within PDF attachments sent along with sharing emails.
