How can I handle connection pooling errors in my Node.js app?

You can handle connection pooling errors by implementing proper error handling in your database connection logic. Use try-catch blocks and listen for error events.

What specific errors should I be looking out for?

Common errors include connection timeouts, connection refused, and max connections reached. Each of these requires different handling strategies.

Can you give me an example of error handling in code?

Sure! Here's a simple example:

const pool = require('your-database-pool');

pool.getConnection((err, connection) => {
  if (err) {
    console.error('Error getting connection:', err);
    return;
  }
  // Use the connection
  connection.release();
});

What about logging these errors?

Logging is crucial! You can use libraries like Winston or Morgan to log errors for better monitoring and debugging.
