Can I change a JSON object that is in module.exports of a .js file programmatically in Node?

Question

I have a .js file with just JSON objects exported. Can I read these in update the objects and write them back to the same file? How? I know how to read a .json file, update it and write it back.

I do something similar on one of my projects but instead of using a JS file I'll store those values in a JSON file. After making your modifications to the object you can do something like this

fs.writeFile('file.json', JSON.stringify(myObj, null, 4), function(err) {
    if (err) {
      //handle error
    }
    else {
      //handle success
    }
  });
