Stuck in loading with mongoose - node.js

Question

I am trying to create a web-application with node.js, mongoose and MongoDB,
I am trying to load the web-page localhost:8800/api/auth/register which is stuck at loading since past 15 minutes.
VS Code Terminal return the following :
(node:2908) UnhandledPromiseRejectionWarning: MongooseError: Operation `users.insertOne()` buffering timed out after 10000ms

My Scripts are as following :
Index.js :
const application = express();
const mongoose = require("mongoose");
const dotenv = require("dotenv");
const helmet = require("helmet");
const morgan = require("morgan");
const userRoute = require("./routes/users");
const authRoute = require("./routes/auth");
dotenv.config();
mongoose.connect(process.env.MONGO_URL, {useNewUrlParser: true, useUnifiedTopology: true}, () => {
console.log("connected to MongoDB")
});
// middleware
application.use(express.json());
application.use(helmet());
application.use(morgan("common"));
application.use("/api/users", userRoute);
application.use("/api/auth", authRoute);
application.listen(8800, () => {
console.log("backend server is running!")
})
Auth.js :
const User = require("../models/User");
// REGISTER
router.get("/register", async (req, res) => {
const user = await new User ({
username: "john",
useremail: "john#gmail.com",
userpswrd: "123456"
})
await user.save();
res.send("oK")
});
module.exports = router
I am also using .env for MONGO VIA URL CONNECTION
Sorry for the bad writing apologies in advance also I am new to this so pls correct me! I know i have done a lot of mistakes,
Thanks for u're sincere time dedication and sympathy

Answer 1

First of all, you must make sure that you are connecting to the database without any error.
To do this, start listening on connect's callback function:
try {
// This configuration is better
mongoose.connect(process.env.MONGO_URL, {
useUnifiedTopology: true,
useNewUrlParser: true,
useCreateIndex: true,
useFindAndModify: false,
}, err => {
if (err) throw Error(err.message);
console.log("connected to MongoDB");
application.listen(8800, () => console.log("backend server is running!"));
});
} catch (error) {
console.log(error);
}
I think you should make this operation in a try-catch statement like this:
// REGISTER
router.get("/register", async (req, res) => {
try {
// Create user in database
const user = await User.create({
username: "john",
useremail: "john#gmail.com",
userpswrd: "123456"
});
res.status(200).json({ success: true });
} catch (error) {
res.status(500).json({ error });
console.log(error);
}
});
module.exports = router;
Then you can see error's details, and server keeps running.
If you can't solve the problem just add a comment here I'll be back ASAP

Answer 2

check your router or wifi if you are using to run mongoose
try with your mobile internet
