# react-big-scheduler ![npm](https://img.shields.io/npm/v/react-big-scheduler.svg?style=plastic)

A scheduler and resource planning component built for React and made for modern browsers (IE10+), IE needs babel-polyfill.  
**From the npm version 0.2.6, Scheduler will use responsive layout by default(set SchedulerData.config.schedulerWidth to a percentage instead of a number).**

[Online demo](https://stephenchou1017.github.io/scheduler/#/)

Inspired by [Full Calendar Scheduler](https://fullcalendar.io/scheduler/).

## API

### 1.SchedulerData

SchedulerData is the view model of Scheduler, we can modify it to control the view of the Scheduler.

#### constructor

```js
constructor(date=moment().format(DATE_FORMAT), viewType = ViewTypes.Week,
                showAgenda = false, isEventPerspective = false,
                newConfig = undefined, newBehaviors=undefined
                localeMoment = undefined)
```

- `date` is a string in `YYYY-MM-DD` format, and is the initial date Scheduler will render. Take the date `2017-12-20`
  for example, Scheduler will render the time window of the week from `2017-12-18` to `2017-12-24` in `ViewTypes.Week`
  view type, and will render the time window of the `2017-12` month in `ViewTypes.Month` view type.
- `viewType` is the initial view type, now Scheduler supports `Day`, `Week`, `Month`, `Quarter`, `Year` 5 built-in view types,
  in addition Scheduler now supports `Custom`, `Custom1`, `Custom2` 3 custom view types at the same time, in which you can control
  the time window yourself, refer to [this example](https://stephenchou1017.github.io/scheduler/#/customtimewindow). `viewType`,
  `showAgenda` and `isEventPerspective` are a group which should be contained in the SchedulerData.config.views array,
  and they together decide which view should be rendered. When `showAgenda` and `isEventPerspective` are both `false`,
  Scheduler will render the resource view, refer to [this example](https://stephenchou1017.github.io/scheduler/#/views).
- `showAgenda` is a bool value, if true, Scheduler will display the agenda view of current view type. Agenda view is
  read only.
- `isEventPerspective` is a bool value, if true, Scheduler will display the task view of current view type. In
  resource view, every slot(row) describes how many events a resource does in the time window, while in task view,
  every slot describes how many events a big task is divided into and who will make it done. Add a `groupId` and
  `groupName` property to every event object, so that the events having the same `groupId` will belong to the same big task and
  be rendered in the same slot in task view. If `groupId` and `groupName` are not provided, SchedulerData will take
  the `id` as the `groupId`, and take the `title` as the `groupName`. See the `eventsForTaskView` in the
  [DemoData.js](https://github.com/StephenChou1017/react-big-scheduler/blob/master/src/DemoData.js) for details.
- `newConfig` is a config object, used to override the [default config](https://github.com/StephenChou1017/react-big-scheduler/blob/master/src/config.js)
  fully or partly.
- `newBehaviors` is a config object, used to override the [default behaviors](https://github.com/StephenChou1017/react-big-scheduler/blob/master/src/behaviors.js)
  fully or partly.
- `localeMoment` is a locale moment object, which is unified used in react-big-scheduler. If not provided, Scheduler will come
  with English(en, United States) locale strings.

#### setLocaleMoment

```js
setLocaleMoment(localeMoment);
```

Used to set locale moment to the schedulerData, if your locale isn't English. By default, Scheduler comes with English(en, United States)

#### setResources

```js
setResources(resources);
```

Used to set the resources(the slots in resource view), make sure that there are no duplicated `resource.id` in the `resources`.
See the demo `resources` in the [DemoData.js](https://github.com/StephenChou1017/react-big-scheduler/blob/master/src/DemoData.js).

#### setEvents

```js
setEvents(events);
```

Used to set the events. the event array should be sorted in ascending order by event.start property.
See the demo `events` in the [DemoData.js](https://github.com/StephenChou1017/react-big-scheduler/blob/master/src/DemoData.js).
If we use the task view, we'd better add the `groupId` and the `groupName` property to each event object, see the
`eventsForTaskView` in the [DemoData.js](https://github.com/StephenChou1017/react-big-scheduler/blob/master/src/DemoData.js) for details.

#### prev

```js
prev();
```

Let the time window scroll to the left once. When `SchedulerData,viewType` is `ViewTypes.Month`, the time window will
scroll a month, when `SchedulerData,viewType` is `ViewTypes.Week`, the time window will scroll a week. `SchedulerData.events`
will be clear after calling this method.

#### next

```js
next();
```

Let the time window scroll to the right once. `SchedulerData.events` will be clear after calling this method.

#### setDate

```js
setDate((date = moment().format(DATE_FORMAT)));
```

Let the time window jump to the provided `date` directly. `SchedulerData.events` will be clear after calling this method.

#### setViewType

```js
setViewType(
  (viewType = ViewTypes.Week),
  (showAgenda = false),
  (isEventPerspective = false)
);
```

Tell SchedulerData to change current view, the `viewType`, `showAgenda` and `isEventPerspective` group should be
provided, and should be contained in the `SchedulerData.config.views` array. `SchedulerData.events` will be clear
after calling this method.

#### setEventGroups

```js
setEventGroups(eventGroups);
```

Used to set the event groups(the slots in task view), make sure that there are no duplicated `eventGroup.id` in the `eventGroups`.
This method is optional, and is needed only when `SchedulerData.eventGroupsAutoGenerated` is `false`.

#### setEventGroupsAutoGenerated

```js
setEventGroupsAutoGenerated(autoGenerated);
```

Tell SchedulerData to generate `SchedulerData.eventGroups` automatically or not. If `true`, SchedulerData will generate the event
groups(slots) automatically according to the `event.groupId` and 'event.groupName' automatically. If `groupId` and 'groupName' are
not provided, SchedulerData will take `event.id` and `event.title` instead.

#### setMinuteStep

```js
setMinuteStep(minuteStep);
```

Used to set minute step for daily view and refresh the render data.

#### toggleExpandStatus

```js
toggleExpandStatus(slotId);
```

Used to toggle slot's(and its children's) expand status.

#### getMinuteStepsInHour

```js
getMinuteStepsInHour();
```

Used to get minute steps in an hour, it equals 60 / SchedulerData.config.minuteStep.

#### addResource

```js
addResource(resource);
```

Add the `resource` to the `SchedulerData.resources`, make sure that `resource.id` is not duplicated. Refer
to [this example](https://stephenchou1017.github.io/scheduler/#/addresource).

#### addEventGroup

```js
addEventGroup(eventGroup);
```

Add the `eventGroup` to the `SchedulerData.eventGroups`, make sure that `eventGroup.id` is not duplicated. Please note
that the `eventGroup` added may be override when `SchedulerData.eventGroupsAutoGenerated` is `true` and
`SchedulerData.eventGroups` is auto-generated.

#### addEvent

```js
addEvent(newEvent);
```

Add the `newEvent` to the `SchedulerData.events`, make sure that `newEvent.id` is not duplicated. SchedulerData will
place the `newEvent` in the right index according to the `newEvent.start` property.

#### updateEventStart

```js
updateEventStart(event, newStart);
```

Update the `newStart` to the `event.start`, `newStart` is a string in `YYYY-MM-DD HH:mm:ss` format(similarly hereinafter).
SchedulerData will replace the `event` in the right index according to the `newStart` value.

#### updateEventEnd

```js
updateEventEnd(event, newEnd);
```

Update the `newEnd` to the `event.end`.

#### moveEvent

```js
moveEvent(event, newSlotId, newSlotName, newStart, newEnd);
```

Update the `newSlotId`, `newSlotName`, `newStart`, `newEnd` of the `event`. In resource view, new slot is a resource,
while in task view, new slot is a event group. SchedulerData will replace the `event` in the right index according
to the `newStart` value.

#### removeEvent

```js
removeEvent(event);
```

Remove the given event from `SchedeulerData.events`.

#### removeEventById

```js

#### getResourceById

```js
getResourceById(resourceId);
```

Returns the resource by `resourceId`, returns `undefined` if not found.

#### isEventInTimeWindow

```js
isEventInTimeWindow(eventStart, eventEnd, windowStart, windowEnd);
```

Returns whether an event is in the time window or not, remind that `eventStart`, `eventEnd`, `windowStart`, `windowEnd`
are all moment objects.
