How to use middleware in all http request in nodejs express

I am creating a middleware in the nodejs application and I want to add header in the request in middleware and send it to the my endpoint index.js request.

middleware1.js

exports.mw1 = function(req, res, next) {
  next();
};

middleware2.js

exports.mw2 = function(req, res, next) {
  next();
};

app.js

var mw1 = require("./middlewares/middleware1");
var mw2 = require("./middlewares/middleware2");

var combinedMiddleware = function compose(middleware) {
  return function(req, res, next) {
    connect
      .apply(null, middleware.concat(next.bind(null, null)))
      .call(null, req, res);
  };
};

app.use(combinedMiddleware([auth, audit]));
app.use("/", index);

index.js

var express = require("express");
var router = express.Router();

router.get("/", function(req, res) {
  res.send("Welcome!!");
});

module.exports = router;

When I am trying to call it http://localhost:3000/ then it returns the 404 Not Found. Instead, it should redirect request to both middleware then to the index.js

GET / 404 8.700 ms - 139

Does anyone know whats wrong with it ?

Maybe I am missing something, but why you don't do: 

var mw1 = require("./middlewares/middleware1");
var mw2 = require("./middlewares/middleware2");

app.use(mw1, mw2);
app.use("/", index);

And change your middleware to : 

module.exports = function(req, res, next) {
    next();
};
