Some basic documentation can be found here.

Hello, i am trying to complete user registration form that uses (HTML,CSS,JS,NODE.JS,PASSPORT.JS

I am trying to make my registration page work. When I type a username and password, I just get {"message":"Registration failed"}. I’m getting the following error:

MongooseError: Operation `users.findOne()` buffering timed out after 10000ms
    at Timeout.<anonymous> (C:pathtoyourfilenode_modulesmongooselibdriversnode-mongodb-nativecollection.js:186:23)
    at listOnTimeout (node:internal/timers:569:17)
    at process.processTimers (node:internal/timers:512:7)

This is my server.js code for the user registration form:

app.post('/user/register', async (req, res) => {
  const { username, password } = req.body;

  try {
    const existingUser = await User.findOne({ username });

    if (existingUser) {
      return res.status(409).json({ message: 'Username already exists' });
    }

    // Create a new user instance
    const newUser = new User({ username, password });

    // Save the user to the database
    await newUser.save();

    console.log('User registered successfully');
    res.status(200).json({ message: 'User registered successfully' });
  } catch (err) {
    console.error(err); // Log the error for debugging
    res.status(500).json({ message: 'Registration failed' });
  }
});

    // Dot env
import dotenv from 'dotenv';
dotenv.config();

// Mongoose Connection
import mongoose from 'mongoose';
mongoose.connect(process.env.MONGO_URI, {
  useNewUrlParser: true,
  useUnifiedTopology: true,
  useCreateIndex: true,
  useFindAndModify: false,
});

//creating main platform
const connectDB = require('./config/db');
connectDB(); // Call the function here
console.log(mongoose.connection.readyState);

app.post('/user/register', async (req, res) => {
  const { username, password } = req.body;

  try {
    const existingUser = await User.findOne({ username });

    if (existingUser) {
      return res.status(409).json({ message: 'Username already exists' });
    }

    // Create a new user instance
    const newUser = new User({ username, password });

    // Save the user to the database
    await newUser.save();

    console.log('User registered successfully');
    res.status(200).json({ message: 'User registered successfully' });
  } catch (err) {
    console.error(err); // Log the error for debugging
    res.status(500).json({ message: 'Registration failed' });
  }
});

    Let me explain each fix I made:

    • I added the dotenv module to load environment variables from a .env file. This way, you can store your MongoDB connection string securely and avoid exposing it in your code. You need to install dotenv as a dependency and create a .env file in your root directory with the following content:
    MONGO_URI=<your connection string>
    • I imported mongoose and used it to connect to your MongoDB database using the MONGO_URI variable. I also passed some options to avoid deprecation warnings and enable some features. You can read more about them [here].
    • I moved the connectDB function call to the top of your server.js file, before using any Mongoose models. This ensures that you establish a connection to your database before performing any queries. The connectDB function is defined in your config/db file and it simply wraps the mongoose.connect() call in a try-catch block.
    • I added a console.log statement to print the mongoose.connection.readyState property. This is a number that indicates the status of the connection: 0 for disconnected, 1 for connected, 2 for connecting, and 3 for disconnecting. You can use this to debug your connection issues.
