If you want to test your connection string, you can use the following code:

const mongoose = require('mongoose');
mongoose.set('strictQuery', true);
async function testConnection() {
  try {
    await mongoose.connect(`YOUR_URI_HERE`, {
      useNewUrlParser: true,
      useUnifiedTopology: true,
    });
    console.log('Connected to MongoDB successfully!');
    process.exit(0);
  } catch (error) {
    console.error('Error connecting to MongoDB:', error);
    process.exit(1);
  }
}
testConnection();

How to run this:

1. Install Node.js (if you haven't already):

   • Mac: Download from nodejs.org or use brew install node

   • Windows: Download from nodejs.org or use choco install nodejs

2. Install mongoose:

   npm install mongoose

3. Save the code as test-connection.js and replace YOUR_URI_HERE with your actual MongoDB connection string

4. Run it:

   • Mac: node test-connection.js

   • Windows: node test-connection.js

If it doesn't work (shows "Error connecting to MongoDB" or similar), re-follow the steps from the previous lesson to ensure you have a valid connection string.
