Quick start

A usage example from the bson README.

jsFull README ↗
import { BSON, EJSON, ObjectId } from 'bson';
// or:
// const { BSON, EJSON, ObjectId } = require('bson');

const bytes = BSON.serialize({ _id: new ObjectId() });
console.log(bytes);
const doc = BSON.deserialize(bytes);
console.log(EJSON.stringify(doc));
// {"_id":{"$oid":"..."}}
