Introduction

Auto decoders are generated at runtime for you and will still garantee that the JSON structure is correct.

They are handy when using F# on both server and client or if your JSON is a one-to-one mapping with your F# type.

type User =
    {
        Name : string
        Age : int
    }

let userJson =
    """
{
    name: "Geralt de Riv",
    age: 92
}
    """

Decode.Auto.fromString<User>(userJson)

// Ok { Name = "Geralt de Riv", Age = 92 }
