Middleware

setMiddleware()

Attach middleware globally to all routes:

const morgan = require("morgan");
app.setMiddleware(morgan("dev"));

Single Middleware

app.setMiddleware(myMiddleware);

Array of Middlewares

app.setMiddleware([cors(), helmet(), morgan("dev")]);

Path-Scoped

app.setMiddleware("/admin", authMiddleware);

Per-Route Middleware

Attach middleware to specific routes using array syntax:

app.addRoute("/dashboard", {
  get: [authMiddleware, (req, res) => {
    res.send("Secure Dashboard");
  }]
});

Middleware Tracking

Kaelum tracks registered middleware, allowing you to list and remove them programmatically:

// List middleware
const list = app.getMiddleware();

// Remove by function reference
app.removeMiddleware(myMiddleware);

Tip

Register middleware before adding routes. Middleware executes in the order of registration.
