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

Connection pooling in Node.js helps manage database connections efficiently. Best practices include using a connection pool library, setting appropriate pool size, and handling connection errors gracefully.

Can you recommend a good library for connection pooling?

Yes, 'node-postgres' for PostgreSQL and 'mysql2' for MySQL are popular libraries that support connection pooling.

How do I configure the pool size?

You can configure the pool size by setting the 'max' property in the pool configuration object. For example, const pool = new Pool({ max: 20 });.

What should I do if a connection fails?

If a connection fails, ensure you have error handling in place. You can listen for 'error' events on the pool and implement retry logic if necessary.
