データベースの追加、削除、変更、クエリをnodejsで実装する方法

<code class="ts">const MongoClient = require('mongodb').MongoClient;
const url = 'mongodb://localhost:27017';
const client = new MongoClient(url);</code>

<code class="ts">const collection = client.db('myDatabase').collection('myCollection');
await collection.insertOne({ name: 'John Doe', age: 30 });</code>

<code class="ts">await collection.deleteOne({ name: 'John Doe' });</code>

<code class="ts">await collection.updateOne({ name: 'John Doe' }, { $set: { age: 31 } });</code>

<code class="ts">const cursor = await collection.find({ age: { $gt: 30 } });
const results = await cursor.toArray();</code>
