To add a new object to existing data in MongoDB, you can use the insertOne() method to insert a single document or the insertMany() method to insert multiple documents. Here is an example using the insertOne() method:
- Connect to your MongoDB database:
1 2 3 4 5 6 7 8 9 10 11 12 13 |
const MongoClient = require('mongodb').MongoClient;
const url = 'mongodb://localhost:27017';
MongoClient.connect(url, { useNewUrlParser: true, useUnifiedTopology: true }, (err, client) => {
if (err) {
console.error('Failed to connect to the database', err);
return;
}
const db = client.db('your-database-name');
// Insert new object here
});
|
- Use the insertOne() method to add a new object to an existing collection:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 |
const newObject = {
key1: 'value1',
key2: 'value2',
};
db.collection('your-collection-name').insertOne(newObject, (err, result) => {
if (err) {
console.error('Failed to insert object', err);
return;
}
console.log('New object added successfully');
client.close();
});
|
- Close the database connection once the operation is complete using client.close().
Make sure to replace your-database-name and your-collection-name with the actual names of your database and collection. Also, replace key1, value1, key2, and value2 with the key-value pairs you want to add to the new object.
