I can I manually specify BSON type in mongodb's NodeJS Driver? I am getting error if I use "$numberLong"

Question

This is How I am framing the document's object before inserting it to the collection

function newTupple(name, email){
return {
  email:email,
  name:name,
  account_status:{
    email_verified:{                  //I want this in Int64
        "$numberLong": `${Date.now()}`
    },
    activated:false
  }
}
}

Then I Insert it like

const new_doc = newTupple("Ninja", "jojo@something.com")
collection.insertOne(new_doc, (err, result)=>{
if(err){
    //err: returns " key $numberLong must not start with '$' "
}
}

I am using npm package mongodb@3.6.0

What am I doing wrong? Or is custom data type not available for JS?

Answer 1

You are using extended json syntax which is inappropriate for constructing object graphs in an application. Instead you should be constructing objects of appropriate types.

For example see here for a Long example.

const BSON = require('bson');
const Long = BSON.Long;

const doc = { long: Long.fromNumber(100) };
