Built-in Types

json-as supports these categories directly:

string
integer and float primitives
bool
Date
Array<T>
StaticArray<T>
Map<K, V>
Set<T>
JSON.Value
JSON.Obj
JSON.Raw
typed arrays
ArrayBuffer

Typed arrays

Typed arrays serialize as JSON arrays of numbers:

ts

const bytes = new Uint8Array(4);
bytes[0] = 10;
bytes[1] = 20;
bytes[2] = 30;
bytes[3] = 40;

JSON.stringify(bytes); // [10,20,30,40]

They also deserialize directly:

ts

const parsed = JSON.parse<Uint8Array>("[10,20,30,40]");

ArrayBuffer

ArrayBuffer is supported directly through the normal generic API:

ts

const encoded = JSON.stringify<ArrayBuffer>(buffer);
const decoded = JSON.parse<ArrayBuffer>(encoded);

Dynamic containers

JSON.Value can also hold and re-serialize built-in typed arrays and ArrayBuffer.
