React-big-calendar: IE 11 missing polyfill

[david-mart]

I recently updated to a newer version and now IE 11 is broken. Even the demo page on your website is not loading - looks like it's missing a polyfill of Object.assign

Same issue, worth using babel-plugin-transform-runtime ?

Same issue, are there any updates regarding this ticket ?

[anissaSanadtech]

You can use es6-shim until the issue is fixed

[hlehmann]

@jquense Did you change something ? I just made the update and there is still a Object.assign(...) in lib/index.js:35.

Can you add babel-plugin-transform-runtime in your .babelrc ?

It would be much smaller if we don't have to include es6-shim.

I have no errors in the console and the calendar doesn't get rendered at all. Not sure what is going wrong. I am using the latest version of the plugin 0.17.0. Does anyone else have this issue too on IE 11?

[bmueller-sykes]

In IE11 with 0.19.0 on their examples page, I get Object doesn't support property or method 'assign'. That's almost certainly a polyfill issue. So, this page doesn't work:

My React project is built on create-react-app, which has a bunch of Babel stuff bundled in. As a result, all I needed to do was add this as the very first import in my index.js file:

import 'babel-polyfill'; //needs to be before React to avoid IE11 warnings

...and then things worked fine. It doesn't look like RBC is build on CRA, so I'm not sure if it's that simple here or not, but it seems like it should be that simple.

[bmueller-sykes]

Actually, to add a little more to the story. Because my project contains babel-polyfill, RBC works in IE11 for me. So it would appear (perhaps obviously) that as long as you have the necessary polyfills somewhere in your project, it'll work. What's weird is that their examples don't have the polyfills.
