Whether you’re a software architect, QA engineer, technical lead, or any other type of developer, you’ll most likely benefit from building a controller function in Node.js. A controller function is a specific piece of code within an application’s architecture—often found in the Model-View-Controller (MVC) pattern—that facilitates communication between the user and the underlying application logic.
Think of the controller function as the master chef in your code kitchen 🔥👨🍳. It takes in your ingredients (user input), works its culinary magic behind the scenes by interacting with the data model, and serves up a deliciously updated UI 🍽️. So, whether you’re coding up a storm or cooking up code, the controller function is your secret sauce to a flavorful application.
And here’s a little extra food for thought: did you know that you can build a controller on the fly with GitHub Copilot?
