TypeError: Cannot read property 'map' of undefined

When I run npm run dev it works fine, but when I hit the URL on browser I'm getting this error (got same error on npm run built):

The error is coming from here, on HtmlDocument.js:59:19

          { images.map(url => <meta property="og:image" content={ url } />) } 

I'm running node v0.12.4

Yes you are right, thanks for reporting this! Let me check what went wrong ... :-)

[gpbl]

It is because this issue with babel. I just pushed an update using a previous version of babel: please pull, clean up node_modules and run npm install to get it running again :-)

git pull
rm -rf node_modules
npm install

As the issue with babel get fixed, we can move again to the latest version.

thank you so much @gpbl, works perfect now 😄

[gpbl]

It should be fixed with the last babel, however :-)

[juancabrera]

yes! tested it and all working fine.

created #74.
