Connecting Node.js to MySQL provides robust relational database capabilities for applications requiring structured data storage and complex queries. As the creator of CoreUI with extensive Node.js experience since 2014, I’ve integrated MySQL with Node.js in numerous enterprise applications for e-commerce and business management systems. The most reliable approach uses the mysql2 library with connection pooling for optimal performance and modern JavaScript support. This method ensures secure, efficient database access while supporting both callback and promise-based patterns.

Connecting Node.js to MongoDB enables persistent data storage for web applications using one of the most popular NoSQL database solutions. As the creator of CoreUI with extensive Node.js experience since 2014, I’ve connected Node.js applications to MongoDB in countless production systems for user data, content management, and analytics. The most reliable approach uses the official MongoDB driver with connection pooling and proper error handling. This method provides robust database connectivity while handling connection failures and maintaining optimal performance.
