Open source alternative to Google Analytics (server side.)

Open Analytics Core

Get real-time online users and save the data to MongoDB database.

Basically what it does is aside from showing real-time total active clients in the node console it also logs the following information to a MongoDB database:

• Device Ip

• User-agent

• IsMobile

• Date

• Active Time (Seconds)

• Visited url

• Location

• Referrer

Requirements

These are the versions that I had so it may work on your PC if you had an older version installed:

• NodeJS (version 16 or later)

• MongoDB (version 5 or later)

• Any other webserver that you want to serve your clients with (even NodeJS)

• OpenSSL (Optional: For HTTPS setup.)

Setup

First Step

Add this code to your client HTML page (Example):

<script src="https://cdn.socket.io/4.4.0/socket.io.js"></script>
<script>
    const socket = io("ADDRESS"); // Enter URL with port
    socket.on('socketClientID', function (socketClientID) {
        socket.emit('clientMessage', {url: window.location.href, referrer: document.referrer}); // Send url and referrer as an object
    });
</script>

Second Step

Run npm install in the main folder.

Third Step

And finally run node index also in the main folder.

HTTPS Setup

If your website is using HTTPS instead of HTTP you'll need to do the steps which are shown below:

First Step

To set up HTTPS support you'll need an SSL certificate. To generate a self-signed certificate, run the following in your shell:

openssl genrsa -out key.pem
openssl req -new -key key.pem -out csr.pem
openssl x509 -req -days 9999 -in csr.pem -signkey key.pem -out cert.pem
rm csr.pem

Second Step

After getting your .pem files just change line 7 to 12 (index.js file) with this:

const options = {
    key: fs.readFileSync('key.pem'), // Edit key.pem file path if needed (Default: Main folder)
    cert: fs.readFileSync('cert.pem'), // Edit key.pem file path if needed (Default: Main folder)
    cors: {
        origin: '*',
      }
}

const https = require('https').createServer(options, app);
const io = require('socket.io')(https, {
    cors: {
      origin: '*',
    }
});

Third Step

You'll need to add the fs module so add const fs = require('fs'); at top of the index.js file.

Fourth Step

Change line 64 to 66 (bottom of the index.js file) with this:

https.listen(PORT, () => {
    console.log("ALL SET!");
});

Fifth Step

Lastly change const socket = io("ADDRESS"); to const socket = io("ADDRESS", {secure: true}); where ever your using the client script.
