What you are looking for is JSON.stringify()

JSON.stringify(objectToSerialize)

You need to use JSON.stringify() and then JSON.parse() to convert bson to valid json.

const dataString = JSON.stringify(data[0]);
const parsed = JSON.parse(dataString);

console.log(parsed._id);

Other bson types may give you its associated representation in Canonical format. For example, if you used the decimal bsonType in your mongodb it will present it like so:

...(continuing from code block above)

console.log(parsed.aDecimalNumber); // { $numberDecimal: 1.00 }

you want to call the .tostring() function on the id field.

The objectId is held as a special type stored in hex to reduce size. You'll need to use the toString function to convert it to the 24 ascii char string

https://github./mongodb/js-bson/blob/1.0-branch/lib/bson/objectid.js#L171-L179

console.log('DATA*** ', data[0]._id.toString());
