Setting _id as raw String on Mongo from NodeJS (Solution: Argument passed in must be a single String of 12 bytes or a string of 24 hex characters)

setting_id_as_string_mongodb_nodejs.js

/* The unwanted complication on monk ('_id' as HEX 12-24 bytes) can be handled by using native mongo driver */

var MongoClient = require('mongodb').MongoClient;

/* values to be changed as per need */
var input = {'_id':'string_value'};
var collection_name = 'collection_name';
var db_name = 'db_name';

MongoClient.connect("mongodb://localhost:27017/"+db_name, function(err, db) {
  	if(err) { return console.dir(err); }
	var collection = db.collection(collection_name);
  	collection.insert(input);
});
