README.md

A couple of demos of user tracking with JavaScript.

I show some methods how to send user data back into the server. More details in my blog article (in Chinese).

• Sync AJAX
• Async AJAX + sync operations
• Async AJAX + setTimeout
• Beacon API
• ping attribute of <a> tag

How to play

First, clone the repo.

$ git clone https://github.com/ruanyf/user-tracking-demos.git
$ cd user-tracking-demos

Install the dependences, then launch the server.

$ npm install
$ node server.js

Visit http://localhost:3000 in your browser. Follow the instruction on the page, then watch what happens in the commandline.
