## Context.getSync() method

Get the synchronous value bound to the given key, optionally return a (deep) property of the bound value.

This method throws an error if the bound value requires async computation (returns a promise). You should never rely on sync bindings in production code.

<b>Signature:</b>

```typescript
getSync<ValueType>(keyWithPath: BindingAddress<ValueType>, options?: ResolutionOptions): ValueType | undefined;
```

## Parameters

|  Parameter | Type | Description |
|  --- | --- | --- |
|  keyWithPath | <code>BindingAddress&lt;ValueType&gt;</code> | The binding key, optionally suffixed with a path to the (deeply) nested property to retrieve. |
|  options | <code>ResolutionOptions</code> | Options for resolution. |

<b>Returns:</b>

`ValueType | undefined`

The bound value, or undefined when an optional binding is not found.

## Example


```ts
// get "rest" property from the value bound to "config"
// use "undefined" when no config is provided
const config = await ctx.getSync<RestComponentConfig>('config#rest', {
  optional: true
});

```
