I'm learning how to use Node.js apps in a server (not my local machine). In this situation, I'm following this tutorial in order to create a simple web server.
I have installed Node.js, and tested via CLI that it works. I can run javascript code, generate output in the CLI, etc. But I can't manage to make the an app work via URL using a browser.
The app folder structure I have is very simple:
index.js
package.json
package-lock.json
This is the code I'm currently working with in index.js:
var http = require('http'); // 1 - Import Node.js core module
var server = http.createServer(function (req, res) { // 2 - creating server
if (req.url == '/') { //check the URL of the current request
// set response header
res.writeHead(200, { 'Content-Type': 'text/html' });
// set response content
res.write('<html><body><p>This is home Page.</p></body></html>');
res.end();
}
else if (req.url == "/student") {
res.writeHead(200, { 'Content-Type': 'text/html' });
res.write('<html><body><p>This is student Page.</p></body></html>');
res.end();
}
else if (req.url == "/admin") {
res.writeHead(200, { 'Content-Type': 'text/html' });
res.write('<html><body><p>This is admin Page.</p></body></html>');
res.end();
}
else
res.end('Invalid Request!');
});
server.listen(5000); //3 - listen for any incoming requests
console.log('Node.js web server at port 5000 is running..')
If I go via CLI to the app's folder and run the app (node index.js), I can see the expected console.log() output (Node.js web server at port 5000 is running..). But if then I go to the URL pointing at that folder, which I would expect to output <html><body><p>This is home Page.</p></body></html>, it doesn't work (see below for what I get).
I have a domain (http://example.com) with document root in the app's folder. Here's what I have tried:
None of those give the response I would expect. I don't know if this is a problem with my file structure, my server configuration... but I've been looking around and I can't figure why this basic example isn't working in my case, clearly I'm missing something. Any help would be much appreciated!
EDIT:
The server where I'm trying to run this app is a LAMP machine with CentOS 7.
