# React Scheduler Component

> :rocket: **Fork Notice**: This is a modernized fork of [@aldabil/react-scheduler](https://github.com/aldabil21/react-scheduler) with:
> - React 19 support
> - MUI 7 / @mui/x-date-pickers 8 support  
> - date-fns 4 support
> - Additional features (see changelog)

[![npm package](https://img.shields.io/npm/v/@isma91/react-scheduler/latest.svg)](https://www.npmjs.com/package/@isma91/react-scheduler)


> :warning: **Notice**: This component uses `mui`/`emotion`/`date-fns`. if your project is not already using these libs, this component may not be suitable.

## Installation

```jsx
npm i @isma91/react-scheduler
```

If you plan to use `recurring` events in your scheduler, install `rrule` [package](https://www.npmjs.com/package/rrule)

## Usage

```jsx
import { Scheduler } from "@isma91/react-scheduler";
```

## Example

```jsx
<Scheduler
  view="month"
  events={[
    {
      event_id: 1,
      title: "Event 1",
      start: new Date("2021/5/2 09:30"),
      end: new Date("2021/5/2 10:30"),
    },
    {
      event_id: 2,
      title: "Event 2",
      start: new Date("2021/5/4 10:00"),
      end: new Date("2021/5/4 11:00"),
    },
  ]}
/>
```

### SchedulerRef

Used to help manage and control the internal state of the `Scheduler` component from outside of `Scheduler` props, Example:

```js
import { Scheduler } from "@isma91/react-scheduler";
import type { SchedulerRef } from "@isma91/react-scheduler/types"

const SomeComponent = () => {
  const calendarRef = useRef<SchedulerRef>(null);

  return <Fragment>
    <div>
      <Button onClick={()=>{
        calendarRef.current.scheduler.handleState("day", "view");
      }}>
        Change View
      </Button>
      <Button onClick={()=>{
        calendarRef.current.scheduler.triggerDialog(true, {
          start: /*Put the start date*/,
          end: /*Put the end date*/
        })
      }}>
        Add Event Tomorrow
      </Button>
    </div>

    <Scheduler
      ref={calendarRef}
      events={EVENTS}
      //...
    />
  </Fragment>
};
```

The `calendarRef` holds the entire internal state of the Scheduler component. Perhaps the most useful method inside the `calendarRef` is `handleState`, example:

```
calendarRef.current.scheduler.handleState(value, key);
```

consider looking inside `SchedulerRef` type to see all fields & methods available.
