Best way to load a very large string into .NET WASM?

[Sebazzz]

Rebuilding an (Electron) application incrementally in .NET using the strangler pattern, I have the need to load a very large serialized object (JSON, >35MB) into .NET. I've noticed that it kinda-breaks when I load such a large string in .NET at once (JSExport).

For this reason I've now chunked this string into 1MB strings, at the .NET side I collect this via a StreamWriter, and finally deserialize it using JsonSerializer.

I wonder if there are better approaches, like serializing it to an [Shared]ArrayBuffer and either pass that directly to .NET or construct an TypedArray like UInt8Array and pass that to .NET? Any suggestions?
