Element: Window is not defined in popper.js

[wubocong]

I got this error when applying ElementUI to Evan You's vue-hackernews-2.0 repository.

webpack:bundle is now VALID.
error during render : /

I use the recommended conf but can't figure out why.
{ test: /\.js$/, loader: 'babel', exclude: /node_modules/ }
I need explanation.

vue-hackernews-2.0 applied SSR, and window is undefined in a Node environment. See #333 for more information.

My God! @Leopoldthecoder, Thanks for your explanation! Maybe I have to use another UI framework...

Hi @Leopoldthecoder is there any way that Element supports server-side rendering?

[Leopoldthecoder]

Now Element doesn't support SSR, and we have no such plan in short term. Sorry.

[Atinux]

No problem @Leopoldthecoder, it was for me to know if it will be compatible with nuxt.js

[ckken]

@Atnux save problem with nuxt.js when use http://element.eleme.io/#/en-US

[jeblister]

@Atnux same problem with nuxt.js when i try to work with element-ui

[Leopoldthecoder]

@Atinux Hi, Element now supports SSR and can work with nuxt.js :)

[Atinux]

You guys rock @Leopoldthecoder 👏

[wubocong]

@Leopoldthecoder great!
