테스트용으로 글하나 만들어보기

 

const { MongoClient, ServerApiVersion } = require("mongodb");
const uri =
  "mongodb+srv://admin:qwer1234@admin.eepuvsg.mongodb.net/?retryWrites=true&w=majority";

// Create a MongoClient with a MongoClientOptions object to set the Stable API version
const client = new MongoClient(uri, {
  serverApi: {
    version: ServerApiVersion.v1,
    strict: true,
    deprecationErrors: true,
  },
});

async function run() {
  try {
    // Connect the client to the server	(optional starting in v4.7)
    await client.connect();
    // Send a ping to confirm a successful connection
    await client.db("admin").command({ ping: 1 });
    console.log(
      "Pinged your deployment. You successfully connected to MongoDB!"
    );
  } finally {
    // Ensures that the client will close when you finish/error
    await client.close();
  }
}
run().catch(console.dir);

export { client };

MongoDB: 애플리케이션 데이터 플랫폼

 

  const clients = await client;
  const db = clients.db("jdb");
  let result = await db.collection("post").find().toArray();
  console.log(result);

db (jdb)와 컬렉션명(post)을 위와 같이 입력하고 콘솔 찍어보기

 

결과가 터미널 콘솔에 잘 찍히면 연결이 잘된 것
