Can't access site.data variable

Hello I have menu.json file in _data folder:

[
  {"url":"","index":"0"},
  {"url":"about","index":"1"},
  {"url":"portfolio","index":"2"},
  {"url":"expertise","index":"3"},
  {"url":"contact","index":"4"}
]

I’m trying to log site.data.menu from main.js:

console.log(site.data.menu)

And have this error:

Can someone help me with this please ?

If you want use files from _data folder in your .js files, you can achieve it with:

var _menu = require('../_data/menu.json');

Works like a charm !
