# @NullCodable

`@NullCodable` is a property wrapper that encodes `nil` optional values as `null` when encoded using `JSONEncoder`. 

On its own, `JSONEncoder` will omit optional properties that are `nil` - meaning that this:

```swift

struct Test: Codable {

  var name: String? = nil

}

```

will be encoded as: `{}`.

If for some reason, you would like optional properties that are nil

to be encoded in JSON as `null`, then marking those properties as `@NullCodable`

will do so.

For example, adding `@NullCodable` like this:

```swift

  struct Test: Codable {

    @NullCodable var name: String? = nil

  }

```

will encode as: `{\"name\": null}`.
