When using json-loader, require(file.json) is broken for server-only libs

Hi,

I got this error when using json-loader + express:

[webpack-isomorphic-tools] [error] asset not found: ./~/statuses/codes.json
/app/node_modules/statuses/index.js:7
status.codes = Object.keys(codes).map(function (code) {
                      ^

TypeError: Cannot convert undefined or null to object
    at Function.keys (native)

It seems that webpack-isomorphic-tools new require is trying to handle resources that are only used server-side (like express).

Here is the webpack-isomorphic-tools config that I use:

export default {
  debug: true,
  assets: {
    json: {
      extensions: ['json']
    },
    svg: {
      extensions: ['svg']
    },
    scss: {
      extensions: ['scss']
    },
  }
}

Thanks.

Yes, you should narrow down your "json" extension scope.
See include and exclude asset type parameters.
