Dynamically Load a Database Client Using ES Modules

Explore how to implement a dynamic factory function to load and instantiate database clients in Node.js based on runtime environment. This lesson teaches you to use ES module dynamic imports to switch between development and production database clients seamlessly, improving modularity and maintainability in backend applications.
