Do you want to request a _feature_ or report a _bug_?

Bug.

What's the current behavior?

TypeError: Cannot read property 'formats' of undefined

When I delete the bigcalendar class, the problem is solved. lol.

What's the expected behavior?

All of copied from your examples. But doesnt works.

My problems is solved, i set localizer props to moment.js.

I would declare your localizer up out of the render() method personally but if what you have works great 👍

What if it does not resolve the issue?

const localizer = BigCalendar.momentLocalizer(moment);
