Learning about Routes, Views, Actions, and Controllers (RVAC) can be confusing at first. It’s not always obvious which part handles what, or why we even need them. When I started, this concept felt intimidating — I wasn’t sure how they all fit together. I’m still learning, but I’ve come to see how important RVAC is for building websites that are easy to navigate and make sense to users.
I’m not a master yet, but I’m striving to get there. My goal here is to break each piece down clearly, so you can understand their roles and see how they connect. Hopefully, my explanation helps you grasp these ideas a little better than when I first encountered them.
🛣 Route — The Traffic Director Routes don’t do the work themselves; they simply decide where the request should go. Think of them as traffic signs pointing the request to the right controller.
🎛 Controller — The Decision Maker The controller decides what happens when a request arrives. It receives the request from the route, coordinates with models (your data and business logic), and determines the response.
⚡ Action — The Specific Task An action is a method inside a controller that handles one type of request. Each action represents a single job — like showing a product, creating a new record, or deleting something.
👀 View — The Presentation Layer A view is the template that presents data to the user. Views don’t make decisions; they simply display the information prepared by the controller in a user-friendly format. If the controller is the chef preparing the meal, the view is the plate and presentation that makes it appealing to the diner.
I’m still mastering these concepts, but each step shows me how essential they are. If you’re learning too, remember: RVAC isn’t just theory — it’s the backbone of websites, making them functional, intuitive, and a joy for people to use.
