react-grid-calendar

React calendar package that supports weekly grid view with vertical columns that are very useful for displaying bookings through the week.

Installing

Run

npm install # or yarn install

Commands

The recommended workflow is to run TSDX in one terminal:

npm start # or yarn start

This builds to /dist and runs the project in watch mode so any edits you save inside src causes a rebuild to /dist.

Configuration

Code quality is set up for you with prettier, husky, and lint-staged. Adjust the respective fields in package.json accordingly.

Rollup

TSDX uses Rollup as a bundler and generates multiple rollup configs for various module formats and build settings. See Optimizations for details.

TypeScript

tsconfig.json is set up to interpret dom and esnext types, as well as react for jsx. Adjust according to your needs.

Usage

Currently there are 2 views, Week Grid view (default) and simple Week view. To use week view simply specify the parameter view like so: view="week"

Week Grid view

You need to specify the columns that contain the events (See stories/GridCalendar.strories.tsx for example). In this case your data should look something like this:

const columns = [
  {
    label: 'Court 1',
    events: [
        {
            eventId: '0000-0000-0000',
            startDate: '2022-08-01 12:00:00',
            endDate: '2022-08-01 13:00:00',
            label: `Level 1`,
            backgroundColor: `#0000ff`,
        },
        {
            eventId: '0000-0000-0001',
            startDate: '2022-08-01 15:00:00',
            endDate: '2022-08-01 16:00:00',
            label: `Level 1`,
            backgroundColor: `#0000ff`,
        }
    ],
    columnData: { id: '000-000-001', name: 'Court 1' }
  }
];

<GridCalendar
    columns={columns}
/>

This will render one column that has 2 events.

Overlapping events

If some events are overlapping they are sorted by 3 things in this order: start date, duration, eventId. Note that eventId is random so if your events have the same start and end dates, they will appear on top of each other in random order.

Availability

By default Calendar in Grid Mode hides the cells that are not inside of availability. If you want to display all the cells do not provie availability property in columns at all.

To disable from clicking and grey out some of the cells that are use the availability object like so:

const columns = [
  {
    label: 'Court 1',
    columnData: { id: '000-000-001', name: 'Court 1' }
    availability: [{ weekDay: 1, startTime: '06:00', endTime: '19:00' }],
  }
];

<GridCalendar
    columns={columns}
/>

Note that presense of empty availability array disables entire column for the day. To make entire day available remove the availability property.

Week view

You need to specify the list of events; Example:

const events = [
        {
            eventId: '0000-0000-0000',
            startDate: '2022-08-01 12:00:00',
            endDate: '2022-08-01 13:00:00',
            label: `Level 1`,
            backgroundColor: `#0000ff`,
        },
        {
            eventId: '0000-0000-0001',
            startDate: '2022-08-01 15:00:00',
            endDate: '2022-08-01 16:00:00',
            label: `Level 1`,
            backgroundColor: `#0000ff`,
        }
    ],

<GridCalendar
    events={events}
    view="week"
/>

This will render the week view with 2 events.

Week mobile view

The week view is responsive. It changes to mobile view at breakpoint 768px. Mobile event renderer and mobile day header are specified separatley from regular event renderer and column header renderer via mobileEventRenderer and mobileDayHeaderRenderer props.

Display date

The calendar library does not provide the UI to change the displayed week instead you can develop your own UI and simply specify the display date using the displayDate parameter and the library will display the week that this date falls into. Example:

<GridCalendar
    columns={columns}
    displayDate={new Date('2000-01-01')}
/>

This will render the week that 1st of January 2000 falls onto.

Events rendering

You can chose to render the events using custom renderer function by passing the eventRenderer function that accepts one parameter event.

<GridCalendar
    columns={columns}
    eventRenderer={(event) => (<div>Event: {event.eventId}</div>)}
/>

Listening to event clicks

You can listen to event clicks by specifying the eventOnClick paramter to the component. Just like renderer function it accepts one parameter event.

<GridCalendar
    columns={columns}
    eventOnClick={(event) => console.log('clicked event: + event.eventId')}
/>

Listening to cell clicks

You can listen to clicks on empty cells by specifying the cellOnClick paramter to the component. This function accepts two parameters columnData [unknown] and date [string]. columnData contains the data provided in the columnData property specified in the column (see Week Grid view section above) and date contains the date associated with the lcicked cell.

<GridCalendar
    columns={columns}
    cellOnClick: (columnData: unknown, date: string) => {
        console.log('col:' + JSON.stringify(columnData) + ' date:' + date);
    }
/>

Column header rendering

You can chose to render the column header using custom renderer function by passing the columnHeaderRenderer function that accepts one parameter column.

<GridCalendar
    columns={columns}
    columnHeaderRenderer={(event) => (<div>{column.label} ({column.events.length})</div>)}
/>

Specifying the locale

To specify the locale to be used in the calendar simply specify 2-letter locale code like 'en', 'es' etc. Default locale is 'en';

<GridCalendar
    columns={columns}
    locale='es'
/>

Hiding time slots in Week Mode

In order to display only the tme slots in Week Mode that start from earliest event and ends at latest use the prop hideUnavailableTime={true}

Collapsable days in mobile view

By default the days in the mobile view are collapsable, meaning that the days in the past will be collapsed initially and all days can be collapsed or expanded by clicking on the day header. To disable this functionality use the mobileDayCollapsable prop.
