Appear: Missing Props

[felixheck]

Hi there – just started with mdx-deck.
It's awesome, thanks!

But having some issues with using Appear.
As soon as use the component the following errors occur and the app breaks.

Warning: Failed prop type: The prop `slide` is marked as required in `Appear`, but its value is `null`.

Warning: Failed prop type: The prop `deck` is marked as required in `Appear`, but its value is `null`.

Haven't found any hint in the docs.

env
npm: 6.2.0
node: 10.9.0
@mdx-js/mdx: 0.15.0
mdx-deck: 1.6.4

Those are just warnings, but is the app not working either?

[felixheck]

There are some errors, I assumed those are due to the warnings. Anyway:

@jxnblk can you provide the source code of the demo? just to check if I'm doing anything wrong..

[jxnblk]

What demo are you referring to? All the source code for this repo is in the repo...

[felixheck]

found it.

The bug seems to occur when using mdx-deck even in the demo — it works when using ../dist (Sometimes). Really weird.

[jxnblk]

I suspect that this might be related to a bug that #144 is attempting to fix. See also pomber/code-surfer#8

[felixheck]

Yep, seems so

[jxnblk]

Just published v1.7.0 – let me know if that resolves the issues you were seeing

[felixheck]

:(

[jxnblk]

Sorry, I’m really not sure what’s happening. Can you try rm -rf node_modules && npm i and try running it on a new mdx file with just a heading and no imports?

[felixheck]

Well it works without the Appear component.
Even this minimal working example does not work:

Works with v1.7.3 👌🏽🎉

[felixheck]

Getting the same errors again with several versions..

[jxnblk]

Closing this since the internals for v2 are quite different and this should be resolved
