Mongodb – Why do it get stuck at processing when using localhost:3000 Thunder Client on VS Code?

Your code looks right, yet there’s one improvement you can make: Move the app.listen call inside the connectDB capability to guarantee that the server begins solely after the information base association is effectively settled.

update code :

index.js file:

const express = require('express');
const app = express();
const connectDB = require('./db');
const port = 3000;

app.use(express.json());

app.use('/api/auth', require('./routes/auth'));
app.use('/api/notes', require('./routes/notes'));

app.get('/', (req, res) => {
    res.send('Hello World!');
});

connectDB().then(() => {
    app.listen(port, () => {
        console.log(`Example app listening at http://localhost:${port}`);
    });
}).catch((err) => {
    console.error('Failed to connect to the database:', err);
});

db.js

const mongoose = require('mongoose');
const mongoURI = "mongodb://127.0.0.1:27017/inotebookdb";

const connectDB = () => {
    return mongoose.connect(mongoURI, { useNewUrlParser: true, useUnifiedTopology: true })
        .then(() => {
            console.log("Successfully connected to the database");
        })
        .catch((err) => {
            console.log("Error connecting to the database:", err);
            throw err;
        });
};

module.exports = connectDB;

In this rendition, the connectDB capability returns a commitment, permitting you to utilize .then, at that point() and .catch() while calling it in index.js. This guarantees that the server will just beginning tuning in after the data set association is laid out effectively.

Furthermore, I’ve added some blunder taking care of in the data set association process, so you’ll see a message on the off chance that there’s an issue interfacing with the data set.

Make sure to introduce the necessary conditions, like express, mongoose, and some other conditions you could have utilized in your courses and models. You can introduce them utilizing npm or yarn:

npm install express mongoose

With these changes, your backend ought to work accurately, and you ought to have the option to utilize ThunderClient or some other Programming interface client to make demands without stalling out in handling.
