Connect mangoDB Atlas with nodejs

Question

I can't connect to MongoDB database, yet I tried everything ! I have successfully replaced the password.

 const mongoose = require("mongoose"); mongoose .connect( "mongodb+srv://vibess:0KksWIBp6slcBLm0@cluster0.iuvoi.mongodb.net/?retryWrites=true&w=majority", { useNewUrlParser: true, useUnifiedTopology: true, useCreateIndex: true, } ) .then(() => console.log("Connected !!")) .catch(() => console.log("Not connected!"));

Here is the Database

You will need another function to complete the operation. the function is usually called run then you need to write all the operations of your server in the scope of this function. here is an example of a server of mine Also you need to declare the name of your database before text retrywrites=true

 //connect to mongodb const uri = `mongodb+srv://${process.env.DB_USER}:${process.env.DB_PASS}@cluster0.qtoag.mongodb.net/Teletale?retryWrites=true&w=majority`; const client = new MongoClient(uri, { useNewUrlParser: true, useUnifiedTopology: true, }); async function run() { try { await client.connect((err) => { const db = client.db("Teletale"); const djiPackages = db.collection("Devices"); const bookingsCollection = db.collection("bookings"); const testimonialCollection = db.collection("testimonials"); const usersCollection = db.collection("users"); // ==============GET API ==================== //GET API app.get("/", (req, res) => { res.send("Welcome to Teletale"); }); //GET API (dji Package) app.get("/Devices", async (req, res) => { const result = await djiPackages.find({}).toArray(); res.send(result); }); //GET API (users) app.get("/users", async (req, res) => { const result = await usersCollection.find({}).toArray(); res.send(result); }); // verify admin data form database app.get("/users/:email", async (req, res) => { const email = req.params.email; const query = { email: email }; const user = await usersCollection.findOne(query); let isAdmin = false; if (user?.role === "admin") { isAdmin = true; } // localhost:5000/users/admin@admin.com will show true res.json({ admin: isAdmin }); }); //GET API (Bookings) app.get("/bookings", async (req, res) => { let query = {}; const email = req.query.email; if (email) { query = { email: email }; } const result = await bookingsCollection.find(query).toArray(); res.send(result); }); //GET Dynamic (Bookings) app.get("/bookings/:id", async (req, res) => { const id = req.params.id; const query = { _id: ObjectId(id) }; const result = await bookingsCollection.findOne(query); res.send(result); }); //GET Dynamic (products) app.get("/Devices/:id", async (req, res) => { const id = req.params.id; const query = { _id: ObjectId(id) }; const result = await djiPackages.findOne(query); res.send(result); }); //GET (testimonials) app.get("/testimonials", async (req, res) => { const result = await testimonialCollection.find({}).toArray(); res.send(result); }); // ==========================POST API========================= //POST API (dji Package) app.post("/Devices", async (req, res) => { const newTours = req.body; const result = await djiPackages.insertOne(newTours); res.send(result); }); //POST API (users) app.post("/users", async (req, res) => { const user = req.body; const result = await usersCollection.insertOne(user); console.log(result); res.send(result); }); //POST API (Bookings ) app.post("/bookings", async (req, res) => { const newBooking = req.body; const result = await bookingsCollection.insertOne(newBooking); res.send(result); }); //POST API (Testimonials ) app.post("/testimonials", async (req, res) => { const newBooking = req.body; // console.log(newBooking); const result = await testimonialCollection.insertOne(newBooking); res.send(result); }); // ======================DELETE API ======================== //DELETE API(Bookings) app.delete("/bookings/:id", async (req, res) => { const id = req.params.id; const query = { _id: ObjectId(id) }; const result = await bookingsCollection.deleteOne(query); res.send(result); }); //DELETE API(drone) app.delete("/Devices/:id", async (req, res) => { const id = req.params.id; const query = { _id: ObjectId(id) }; const result = await djiPackages.deleteOne(query); res.send(result); }); // =================Update API==================== app.put("/bookings/:id", async (req, res) => { const id = req.params.id; const newStatus = req.body; const query = { _id: ObjectId(id) }; const options = { upsert: true }; const updateDoc = { $set: { data: newStatus.newData, }, }; const result = await bookingsCollection.updateOne( query, updateDoc, options ); res.send(result); }); //upsert Google user data app.put("/users", async (req, res) => { const user = req.body; const filter = { email: user.email }; const options = { upsert: true }; const updateDoc = { $set: user }; const result = await usersCollection.updateOne( filter, updateDoc, options ); res.json(result); }); // add admin role app.put("/users/admin", async (req, res) => { const user = req.body; const filter = { email: user.email }; const updateDoc = { $set: { role: "admin" } }; const result = await usersCollection.updateOne(filter, updateDoc); res.json(result); }); }); } finally { // await client.close(); } }
