As my username implies, I'm new to node.js. I'm trying to learn it. As part of this process, I'm working to setup a basic web site. This web site will show a couple of basic web pages and expose a single REST endpoint. The structure of my project is:
config.js
home.html
start.js
routes.js
server.js
resources
css
style.css
images
up.png
down.png
javascript
home.html.js
start.js has my main server code. That file gets executed via command line using 'node start.js'. Once started, my server begins listening on port 3000. The code in start.js looks like this:
var express = require('express');
var app = express();
var UserProfileHandler = require('./app/handlers/UserProfileHandler');
app.configure(function () {
app.engine('html', require('ejs').renderFile);
app.set('views', __dirname + '/');
app.use(express.logger({ stream: expressLogFile }));
app.use(express.bodyParser());
app.use(express.methodOverride());
app.use(app.router);
app.use(express.static(__dirname + '/public'));
});
var routes = {
userProfiles: new UserProfileHandler()
};
function start() {
routeConfig.setup(app, routes);
var port = process.env.PORT || 3000;
app.listen(port);
console.log("SUCCESS: Server listening on port %d in %s mode", port, app.settings.env);
}
exports.start = start;
exports.app = app;
My routes.js file has the following:
function setup(app, routes) {
viewSetup(app);
apiSetup(app, routes);
}
function viewSetup(app) {
app.get('/', function (req, res) {
res.render("/home.html");
});
app.get('/home.html', function (req, res) {
res.render("/home.html");
});
}
function apiSetup(app, routes) {
app.get('/api/userProfiles/:username', routes.userProfiles.getUserProfiles);
}
I am trying to load home.html in a browser window. I attempt this by visiting http://localhost:3000 and http://localhost:3000/ and http://localhost:3000/home.html. Unfortunately, none of these work. In fact, I receive an error that says:
Express 500 Error: Failed to lookup view "/home.html"
I know that I'm close. If I visit http://localhost:3000/api/userProfiles/me I receive a JSON response back like I'm expecting. For some reason, i can't seem to return HTML though. My home.html file looks like the following.
<html>
<head>
<script type='text/javascript' src='/resources/javascript/home.html.js'></script>
</head>
<body>
We're up and running! <img src='/resources/images/up.png' />
</body>
</html>
Its a pretty basic HTML file. Even if the HTML comes back though, I'm concerned the JavaScript file and Image it references won't be accessible. I'm concerned of this because I'm not really sure how paths and such work in Node.
How do I get home.html to work in my Node setup?
Thank you!

as your view file is in same folder as your main file, below changes should make it work
from
app.set('views', __dirname + '/');//wont work
to
app.set('views', __dirname);//will work
from
res.render("/home.html");//wont work
to
res.render("home.html");//will work
with both the changes, the view should be working fine
the issue you mentioned regarding the images,css and js is due to the static folder configuration which should be changed from
app.use(express.static(__dirname + '/public'));
to
app.use(express.static(__dirname + '/resources'));
as your static folder is named resources.
but make sure in your view you are refering the css/js/image files like
eg:
/css/style.css
/images/up.png
/images/down.png
/javascript/home.html.js
from your view file
Also if the above dint work, check if you have given the path correctly and also you can try by taking the
app.use(express.static(__dirname + '/resources'));
before the
app.use(express.methodOverride());
app.use(app.router);
lines like
app.configure(function () {
app.engine('html', require('ejs').renderFile);
app.set('views', __dirname + '/');
app.use(express.static(__dirname + '/public'));
//try changing the position of above line in app.configure and resatrt node app
app.use(express.logger({ stream: expressLogFile }));
app.use(express.bodyParser());
app.use(express.methodOverride());
app.use(app.router);
});
