Package Exports

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (json-as) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

AS-JSON

Installation

~ npm install json-as

~ npm install visitor-as

For arbitrary-length numbers, use

~ npm install as-bignum

Add the transform to your asc command

--transform json-as/transform

Or, add it to asconfig.json

{
  "options": {
    "transform": ["json-as/transform"]
  }
}

Usage

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

// @json or @serializable work here
@JSON
class Vec3 {
  x!: f32;
  y!: f32;
  z!: f32;
}

@JSON
class Player {
  firstName!: string;
  lastName!: string;
  lastActive!: i32[];
  age!: i32;
  pos!: Vec3 | null;
  isVerified!: boolean;
}

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
};

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

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

Notes

Performance is nearly equal to the JavaScript JSON implementation which is in C++.
