@jarvis-studio/scheduler-core

Headless, framework-agnostic scheduler engine — the brains behind @jarvis-studio/scheduler-react. Zero React, zero DOM: a store + reducer, typed event bus, command API, plugin system, permission & lifecycle layers, layout engines, an RFC-5545 recurring engine, and Gantt critical-path computation.

npm i @jarvis-studio/scheduler-core

import { createScheduler } from '@jarvis-studio/scheduler-core';

const scheduler = createScheduler({ adapter /* a DateAdapter */ });
scheduler.commands.createEvent({ title: 'Standup', start, end });
scheduler.on('event:create', ({ event }) => console.log(event));

You normally consume this through a binding (e.g. the React package) plus a date adapter (@jarvis-studio/scheduler-adapter-date-fns or -dayjs).
