ExpressJS routing errors

I'm trying to create a collection of microservices. The problem is, my routes don't seem to redirect to the right place.

Here is my index.js file:

var express = require("express");
var app = express();
var port = process.env.PORT || 3000;
var timestamp = require("./routes/timestamp");

app.listen(port, function(){
console.log("Listening on port " + port);

app.get("/", function(req, res){
res.writeHead(200, {"Content-Type": "text/html"});
res.end("Hi! This is a collection of microservices. <a href=''>See instructions here.</a>");

app.get("/timestamp", timestamp);

And here is my 'timestamp' file:

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

router.get("/", function(req, res){
res.send("Hello world!");

router.get("/:date", function(req, res){
var newDate =;

var natural = moment.utc(newDate, "MMMM D, YYYY", true);
var unix = moment.utc(newDate, "X", true);

if (natural.isValid() || unix.isValid()) {
if (natural.isValid()) {
newDate = natural;
} else {
newDate = unix;

res.json({unix: newDate.format("X"), natural: newDate.format("MMMM D, YYYY")});
} else {
res.json({unix: null, natural: null});


module.exports = router;

Here is whats SUPPOSED to happen:

localhost/timestamp should give me "Hello World!"
localhost/timestamp/someDate should give me a JSON file with the dates

But here is what actually happens:

localhost/timestamp gives me a JSON file with the dates
localhost/timestamp/someDate gives me a Cannot GET error
And the "Hello World" is never shown

Change the line app.get("/timestamp", timestamp); to app.use("/timestamp", timestamp);.

I think you intended mounting the timestamp Router middleware on /timestamp path, and not as a callback to a GET request which is what you are currently doing.
