Class ObjectId

Represents an ObjectId that can be used as an _id in the DataAPI.

Provides methods for generating ObjectIds and getting the timestamp of an ObjectId.

Example

const collection = await db.createCollection('myCollection'. {
  defaultId: {
    type: 'objectId',
  },
});

await collection.insertOne({ album: 'Inhuman Rampage' });

const doc = await collection.findOne({ album: 'Inhuman Rampage' });

// Prints the ObjectId of the document
console.log(doc._id.toString());

// Prints the timestamp when the document was created (server time)
console.log(doc._id.getTimestamp());
Copy

Example

await collection.insertOne({ _id: new ObjectId(), album: 'Sacrificium' });

const doc = await collection.findOne({ album: 'Sacrificium' });

// Prints the ObjectId of the document
console.log(doc._id.toString());

// Prints the timestamp when the document was created (server time)
console.log(doc._id.getTimestamp());
