Installation

npm

npm install @yarunoka/core

That is the whole installation. The package registers nothing, runs no install scripts, and has no bootstrapping step — every entry point is a named export you import yourself.

Caution

The 0.x releases exist to exercise the release pipeline and to track the specification on its way to 1.0.0. They are not intended for use.

The Temporal polyfill

Node.js 26 or newer has Temporal built in and needs no polyfill — see Requirements. For runtimes without the Temporal API, install a polyfill once, in your application:

npm install temporal-polyfill

import 'temporal-polyfill/global';

The polyfill belongs to the application rather than to this package — an environment that has Temporal natively should not carry one, and only the application knows which environments it runs in.

Verifying the installation

import { parse } from '@yarunoka/core';

const document = parse({
  version: '1.1',
  timezone: 'Asia/Tokyo',
  schedules: [{ days: [25], times: ['10:00'] }],
});

document.timezone;          // "Asia/Tokyo"
document.schedules.length;  // 1
