FSharp.Json

Newtonsoft's Json.Net is the library of choice for Json serialization. Unfortunately the built-in converters generate rather verbose and ugly Json for certain F# data types like discriminated unions and option types. The module Microsoft.FSharpLu.Json provides more succinct serialization for those types.

To use our serializer open the module with

open Microsoft.FSharpLu.Json

To serialize an object using the default Json.Net format you can use Default.serialize.

Option type

The following examples shows how JSon.net serializes a simple value of type (int option) list:

Default.serialize [Some 5; None; Some 6]

val it : string = "
[
    {
        "Case": "Some",
        "Fields": [ 5 ]
    },
    null,
    {
        "Case": "Some",
        "Fields": [ 6 ]
    }
]"

Using the compact serializer provided by FSharpLu.Json the same objects gets serialized instead as a one-liner heterogeneous array:

Compact.serialize [Some 5; None; Some 6]

val it : string = "[ 5, null, 6 ]"

Discriminated unions

Now let's take a look at simple field-less discriminated unions. Take for instance the type type SimpleDu = Foo | Bar. The value Foo gets serialized by Json.Net as follows:

Value Default (Json.net) Compact
Foo { "Case": "Foo" } "Foo"

Discriminated unions with fields

Our serializer also supports generic discrimnated unions with fields for instance take the following binary Tree example:

type 'a Tree = Leaf of 'a | Node of 'a Tree * 'a Tree
let x = Node (Node((Leaf 1), (Leaf 4)), Leaf 6)

Default Json.net serialization:

Default.serialize x

val it : string = "
{
    "Case": "Node",
    "Fields": [
        {
            "Case": "Node",
            "Fields": [
                    {
                        "Case": "Leaf",
                        "Fields": [ 1 ]
                    },
                    {
                        "Case": "Leaf",
                        "Fields": [ 4 ]
                    }
                ]
        },
        {
            "Case": "Leaf",
            "Fields": [ 6 ]
        } ]
}"

where FSharpLu.Json produces the more succinct and easier to read:

Compact.serialize x

val it : string = "
{
    "Node": [
        {
            "Node": [
                { "Leaf": 1 },
                { "Leaf": 4 }
            ]
        },
        { "Leaf": 6 }
    ]
}"

Backward compatibility with Json.Net

FSharpLu.Json incldues a third serializer called BackwardCompatible. While it produces the same Json as the compact serializer it can deserialize Json in both compact format as well as the default format produced by the stock JSon.net serializer.

This is helpful when migrating projects from Json.Net to FSharpLu.Json as it lets you deserialize Json that was produced by earlier versions of your code.

Expressed more formally this serializer verifies the following properties:

  • BackwardCompatible.serialize = Compact.serialize
  • Default.serialize >> BackwardCompatible.deserialize = id
  • Compact.serialize >> BackwardCompatible.deserialize = id
