Sure, here is a Node.js script to seed your MongoDB database with sample data:

JavaScript

const MongoClient = require('mongodb').MongoClient;
const url = 'mongodb://localhost:27017/mydb';

const seedData = [
  { name: 'John Doe', age: 30, address: '123 Main Street' },
  { name: 'Jane Doe', age: 25, address: '456 Elm Street' },
  { name: 'Peter Smith', age: 40, address: '789 Oak Street' },
];

async function seedDatabase() {
  const client = await MongoClient.connect(url);
  const db = client.db('mydb');

  const collection = db.collection('people');
  await collection.insertMany(seedData);

  console.log('Database seeded successfully');
}

seedDatabase();

This script first imports the MongoClient module from the mongodb package. It then defines the MongoDB connection URL, which is mongodb://localhost:27017/mydb.

Next, the script defines an array of sample data. The sample data consists of three people, with their names, ages, and addresses.

The seedDatabase() function then connects to the MongoDB database and gets the people collection. The function then inserts the sample data into the collection.

Finally, the seedDatabase() function logs a message to the console indicating that the database has been seeded successfully.

To run this script, you can save it as a file called seed.js and then run it from the command line:

node seed.js

This will seed your MongoDB database with the sample data.
