Real-time Visitor Globe with Node.js and WebGL

In this post we would like to share with you a cool project we created by using Node.js and WebGL. It’s a mapped globe of the Earth that you can use to keep track of the people who use your web apps in real-time. After a quick setup, you’ll be able to see the location of everyone who is at your website, pinpointed on the globe and grouped by country. The demo is also fully responsive and works on mobile devices (as long as they support webgl).

How we did it

  • For the server side of the app we’ve used a few Node.js modules:
    • Express is the web framework.
    • Request for doing ajax requests in Node.
    • Is-bot for catching search engine crawlers.
  • The globe:
  • The design:
    • The side menu is animated entirely with CSS.
    • Some jQuery for the front-end.
  • Finding the coordinates of IP addresses was done with the help of

How to run it

If you want to run this app locally, the first thing to do is to make sure you have node.js installed on your machine. After that, download and unzip the archive with the code (you can download it from a button above) to a folder named nodejs-visior-globe. When that’s done, open up a terminal and navigate to the newly created folder. Once there, run the command below to install the needed npm packages:

npm install

When this process is complete run the following code and go to http://localhost:8888 in your browser.

node app.js

There you will see the globe. However, you might notice that there isn’t anyone on the map. That’s because the whole thing is working offline and since we need an active server this won’t be enough.

Integrating it with your site

There are two things you need to do before you see your website visitors on the globe:

  1. Upload the app to a hosting service like heroku. We’ve covered how to deploy your code to heroku previously. The instructions are exactly the same. The only difference is that you will end up with the URL of your new globe rather than the private chat app.
  2. Include a special tracking image on your site. You can do this by adding this html to the footer of every page of your site <img src="http://yourglobe/ping" width="1" height="1" style="display:none" />. Replace yourglobe with the heroku url of your app. If you load the src url of the image in a browser, you should see the text “Done”.

A tracking image is an invisible image that is embedded on every page of your website, and which points to When people load your site, their browser loads all images automatically, which causes the tracking URL to also be loaded. Our app listens for that specific URL, and gets the ip address of the visitor, finds their location and saves it. Users are considered to be online up to 5 minutes after visiting your site (this can be configured in app.js).

All done! You can now enjoy your real time visitor globe!
