Connection pooling in Jamstack apps with PostgreSQL

This text explains the process and benefits of using PostgreSQL with Next.js for building a Jamstack application, emphasizing the importance of connection pooling to enhance database performance. Jamstack is highlighted as a modern web development architecture that separates the code, infrastructure, and content, allowing for faster client-side experiences. The article discusses setting up a PostgreSQL database and introduces connection pooling as a method to manage database connections efficiently, reducing the overhead caused by multiple client requests. It describes various types of connection pooling, such as framework, standalone, and persistent connection pooling, and demonstrates how to implement these techniques using the node-postgres library. By pre-allocating connections and reusing them, connection pooling minimizes the time and resources needed for establishing new connections, thus improving application performance. The text also includes a performance comparison between traditional connection handling and connection pooling, showcasing the latter's advantages in handling large concurrent requests. Through these insights, the article underscores the significance of connection pooling in optimizing database connectivity for modern web applications.
