需要大JSON文件时，NodeJS：“ toString（）”失败

Question

I am trying to load a very large JSON file (360 Mb) on Node + Express but the line below returns this error. How should I process it then?

var emails = require("../fake_IO/cleaned_data_lang.json");

ERROR:

Try to use noded fs fs.createReadStream() instead of require the file directly. I found a comment somewhere about it, give it a go. #here
