"Cannot GET /" with Connect on Node.js

I'm trying to start serving some static web pages using connect like this:

var connect = require("connect");
var nowjs = require("now");
var io = require("socket.io");


var app = connect.createServer(
  connect.static(__dirname + '/public')
);

app.listen(8180);

So I added a simple index.html at the /public directory on the same directory as the app.js file is, but when I try to view the page on my browser I get this response from node:

Cannot GET /

What am I doing wrong and how can I correct it?

That was a silly mistake , I commented out the line that app.js uses for referencing routes.

This fix was to remove using express() directly.

And inside app.js you can define your customize routes

The Straight Forward Answer, include the code in your Node/Server index.js file

const path = require("path"); // include this in the file

router.get("/*", function(req, res) {
  res.sendFile(path.join(__dirname, "../public", "index.html"));
});

And if your are using navigate() in your reactApp use the above code at the end of the file.

  1. open cmd and go to the path of your project.(make sure that you are in "clientApp")
  2. then build your project with "ng build" command. if there is an error the console will give you the error. build error

now you know what your error is.

The solution to "Cannot Get /" can usually be determined if you do an "ng build" in the command line. You will find most often that one of your "imports" does not have the correct path.

You might be needed to restart the process if app.get not working. Press ctl+c and then restart node app.

You'll see the message Cannot GET / if you don't specify which page it is that you're trying to get, in other words if your URL is something like http://localhost:8180. Make sure you enter a page name, e.g. http://localhost:8180/index.html.

You may be here because you're reading the Apress PRO AngularJS book...

As is described in a comment to this question by KnarfaLingus:

[START QUOTE]

The connect module has been reorganized. do:

npm install connect

and also 

npm install serve-static

Afterward your server.js can be written as:

var connect = require('connect');
var serveStatic = require('serve-static'); 
var app = connect(); 

app.use(serveStatic('../angularjs')); 

app.listen(5000);

[END QUOTE]

Although I do it, as the book suggests, in a more concise way like this:

var connect = require('connect');
var serveStatic = require('serve-static');

connect().use(
    serveStatic("../angularjs")
).listen(5000);

Had the same issue. It was resolved as described above.

In my index.js

var port = 1338,
express = require('express'),
app = express().use(express.static(__dirname + '/')),
http = require('http').Server(app),
io = require('socket.io')(http);

app.get('/', function(req, res){
    res.sendFile(__dirname + '/index.html');
});

io.on('connection', function(socket){
    console.log('a user connected');
});

http.listen(port, function(){
    console.log("Node server listening on port " + port);
});

and in my index.html

<!doctype html>
<html>
    <head>
        <title>
            My page
        </title>
    </head>
    <body>
        <script src = "lib/socket.io.js"></script>
        <script src = "lib/three.js"></script>
        <script>
            var socket = io();
        </script>
    </body>
</html>

the three.js was just in there for path testing. This will set all child files to start at the root directory of your app. Also socket.io.js can be called automatically using <script src = "/socket.io/socket.io.js"> through some dark magic (since there is physically a node_modules and lib directory in between) .

The easiest way to serve static files is to use "harp". It can be found here. You can serve up your files from the location you want via node is:

var harp = require("harp")
harp.server(projectPath [,args] [,callback])

Hope this helps.

You may also want to try st, a node module for serving static files. Setup is trivial.

npm install connect

npm install st

And here's how my server-dev.js file looks like:

var connect = require('connect');
var http = require('http');
var st = require('st');

var app = connect()
    .use(st('app/dev'));

http.createServer(app).listen(8000);

or (with cache disabled):

var connect = require('connect');
var http = require('http');
var st = require('st');

var app = connect();

var mount = st({
  path: 'app/dev',
  cache: false
});

http.createServer(function (req, res) {
  if (mount(req, res)) return;
}).listen(8000);

app.use(mount);

var connect = require('connect');
var serveStatic = require('serve-static');
var app = connect(); 
app.use(serveStatic('../angularjs'),  {default: 'angular.min.js'}); app.listen(3000);

You typically want to render templates like this:

app.get('/', function(req, res){
  res.render('index.ejs');
});

However you can also deliver static content - to do so use:

app.use(express.static(__dirname + '/public'));

Now everything in the /public directory of your project will be delivered as static content at the root of your site e.g. if you place default.htm in the public folder if will be available by visiting /default.htm

Take a look through the express API and Connect Static middleware docs for more info.

This code should work:

var connect = require("connect");

var app = connect.createServer().use(connect.static(__dirname + '/public'));

app.listen(8180);

Also in connect 2.0 .createServer() method deprecated. Use connect() instead.

var connect = require("connect");

var app = connect().use(connect.static(__dirname + '/public'));

app.listen(8180);
