# Extra Json Decode / Encode functionality

An extension of the `elm/json` package providing a set of helpers for working
other types of data (mostly the `Posix` data type from the `elm/time` package).

# Example

```elm
import Time exposing (Posix)
import Json.Decode as Decode
import Json.Decode.Extra as Decode
import Json.Encode as Encode
import Json.Encode.Extra as Encode

exampleDecoder : Decode.Decoder Posix
exampleDecoder =
    Decode.field "created_at" Deocde.iso8601

exampleEncoder : Posix -> Encode.Value
exampleEncoder createdAt =
    Encode.object
        [ ( "created_at", Encode.iso8601 createdAt ) ]
    -->
```
