What are the best practices for database connection pooling in Node.js?

Some best practices include configuring the pool size based on your application's needs, using a connection timeout, and handling errors gracefully.

How do I configure the pool size?

You can configure the pool size by setting the max property in your connection pool options, which defines the maximum number of connections.

What happens if the pool size is too small?

If the pool size is too small, your application may experience delays or timeouts when trying to acquire a connection, leading to performance issues.

Can you give an example of handling errors in connection pooling?

Certainly! You can use a try-catch block around your database queries and implement a retry mechanism for transient errors.
