Localization for labels

All shown labels can be localized now.

See https://grubersjoe.github.io/react-activity-calendar/?path=/story/activity-calendar--with-localized-labels

Skeleton component

A new Skeleton component is exported to show the loading state in a more convenient manner:

import Calendar, { Skeleton as CalendarSkeleton } from 'react-activity-calendar';

// ...

const render = loading ? <CalendarSkeleton loading /> : <Calendar data={data} />;

Of course you still can use the loading property of the calendar component directly. However, the calendar requires the data property.

First release

This component was extracted from grubersjoe/react-github-calendar to improve reusability. I hope it is useful for someone :).
