Usage

import { JSON } from "json-as/assembly";
import { u128 } from "as-bignum/assembly";

// @ts-ignore
@json
class Stats {
  wins: u128
  loss: u128
}
// @ts-ignore
@json
class Vec3 {
  x: f32;
  y: f32;
  z: f32;
}

// @ts-ignore
@json
class Player {
  firstName: string;
  lastName: string;
  lastActive: i32[];
  age: i32;
  pos: Vec3 | null;
  isVerified: boolean;
  stats: Stats
}

const player: Player = {
  firstName: "Emmet",
  lastName: "West",
  lastActive: [8, 27, 2022],
  age: 23,
  pos: {
    x: 3.4,
    y: 1.2,
    z: 8.3
  },
  isVerified: true,
  stats: {
    wins: u128.fromString("443"),
    loss: u128.fromString("693")
  }
};

const stringified = JSON.stringify<Player>(data);

const parsed = JSON.parse<Player>(stringified);
