Router

ELI5 — The Vibe Check

The router is the traffic cop of your backend. Every incoming request goes through the router first, and it decides which piece of code should handle it based on the URL. Without a router, requests would just get lost.

Real Talk

A router is a component that matches incoming requests to their appropriate handler functions based on the HTTP method and URL path. It organizes routes and can apply middleware to groups of routes, keeping the application structure clean.

const userRouter = express.Router();
userRouter.get('/', getUsers);
userRouter.post('/', createUser);
app.use('/api/users', userRouter);

When You'll Hear This

"Set up a router for all the auth endpoints." / "The router is returning 404 for that path."
