Using Text.JSON

[ripe pawn]

We've used Newtonsoft directly in pwsh, with a new module we're hoping to use Text.JSON, has anybody done this?

I've run into issues implementing JSONConverter

[crude bridge]

JsonConverter<> won't be possible to implement in pure PowerShell script as it uses ref structs

[ripe pawn]

We're attempting to deserialize a property that is a hash table, which by default will deserialize to this JsonElement. Presumably I'm stuck fixing that in post where in Newtonsoft I could use a converter

I don't know enough about STJ to know if there is a different route you could take, but I can tell you if you are required to implement a method that utilizes a ref struct, that's gonna be a no go

C# or sticking with newtonsoft are likely the two options yeah

I have a couple of pure-pwsh examples where my class is basically a record pattern:

Sometimes all you need are a JsonAttributes on your record, to give it hints to auto coerce for you.
This route doesn't require [ref] structs

For the pwsh version: the basic invocation is [de]serialize( object, type )

[Text.Json.JsonSerializer]::Deserialize( '7', [ConsoleColor] ) # output -is [ConsoleColor]

Using a custom class:

class User {
    [Int]    $Id   = 0
    [string] $Name = 'anonymous'
}

$bob = [User]@{ Name = 'bob' }

$json       = [Text.Json.JsonSerializer]::Serialize( $bob, [User] )
     # out: {"Id":0,"Name":"bob"}

$round_trip = [Text.Json.JsonSerializer]::Deserialize( $json, [User] )
$round_trip -is [User] # out: True

Note: $round_trip is not a [PSCO]

Here's an older gist using these field attributes

[JsonIgnoreAttribute( Condition = [JsonIgnoreCondition]::WhenWritingNull ) ]
[Serialization.JsonIgnoreAttribute()]
