Event Object

{
  id: 1,
  description: 'Event',
  startDate: new Date(),
  endDate: new Date(),
  color: 'blue',
  // ... more properties if needed,
}

Methods

To use the component methods save a reference to it:

<WeekView
  // ... other props
  ref={(ref) => { this.weekViewRef = ref; }}
/>

• goToDate(date, animated = true): when called, the component navigates to a custom date. Note: if the target date has not been rendered before, there may be a delay on the animation. See this issue for details.

Custom EventComponent

The component will be rendered inside a TouchableOpacity, which has the background color set to event.color, and is placed with absolute position in the grid. The component receives two props:

• event (Event) - Event object as described before.
• position: (Object) - object containing top, left, height and width values in pixels.

For example, to display an icon inside each event, such as a react-native-elements Icon:

const MyEventComponent = ({ event, position }) => (
  <Icon
    name={event.iconName}
    type={event.iconType}
    color={event.color}
    size={position.height}
  />
);

<WeekView
  // ... other props
  EventComponent={MyEventComponent}
/>

Locales customization

There's a addLocale function to add customized locale for the component. The component depends on momentjs, you can refer to https://momentjs.com/docs/#/customization/ for more information.

Example:

export WeekView, { addLocale } from 'react-native-week-view';
// add customized localed before using locale prop.
addLocale('fr', {
  months: 'janvier_février_mars_avril_mai_juin_juillet_août_septembre_octobre_novembre_décembre'.split('_'),
  monthsShort: 'janv._févr._mars_avr._mai_juin_juil._août_sept._oct._nov._déc.'.split('_'),
  weekdays: 'dimanche_lundi_mardi_mercredi_jeudi_vendredi_samedi'.split('_'),
  weekdaysShort: 'dim._lun._mar._mer._jeu._ven._sam.'.split('_'),
});

TODO

• allow to swipe between weeks or days.
• header should be swipeable with columns.
• allow to click on grid view.
• allow to drag drop events to specific time and date.
