How to add uuid in data.json file in Node.js?

I have a data set in data.json file. I need to add 'uuid' field to each record. The project is in Node.js.

I can read the file by using 

module.exports.api = function(server, fs) {

  // Sample Rest Call
  server.get('/api/getData', function(req, res) {

    fs.readFile(__dirname + '/data.json', function(err, data) {
      if (err) throw err;
      res.send(200, JSON.parse(data));
    });

  });
};

I have the option to use mongoose as well.

This is by no means 100% efficient, there are of course better solutions. But you could manipulate the data returned from the JSON by looping through it and setting the index as the UUID of the current object being looped through. Like this

module.exports.api = function(server, fs) {

// Sample Rest Call

server.get('/api/getData', function(req, res) {

    fs.readFile(__dirname + '/data.json', function(err, data) {
        if (err) throw err;
        let results = JSON.parse(data);
        let resultsWithUUID = [];
        result.forEach((res, index) => {
           res.uuid = index;
           resultsWithUUID.concat([res]);
        }
        res.send(200, resultsWithUUID);

    });
});
};
