const uri = "mongodb+srv://:@cluster.mongodb.net/test?retryWrites=true&w=majority";
// Create a new MongoClient
const client = new MongoClient(uri, { useNewUrlParser: true, useUnifiedTopology: true });
async function main() {
    try {
        // Connect to the MongoDB Atlas cluster
        await client.connect();
        // Access a specific database
        const db = client.db("myDatabase");
        // Access a specific collection within the database
        const collection = db.collection("myCollection");
        // Perform database operations
        const result = await collection.insertOne({ key: "value" });
        console.log("Document inserted with _id:", result.insertedId);
    } catch (error) {
        console.error("Error:", error);
    } finally {
        // Close the connection
        await client.close();
    }
}
main();
