Front-End Tracker


Keep track of events that can happen in a webpage.

Disclaimer:
This add-on is not for web development. It is meant for testing web sites (debug, security). Its features may cause sites to break entirely, and which can cause privacy or even security issues. Use at your own risk.

Installation

``bash
npm install --save @zaproxy/front-end-tracker
`

Usage

When imported into a webpage, it exposes a mailbox variable in the global scope, which is a PubSub object with the following topics:
* dom-events
* storage

You can then react to these topics by subscribing to the mailbox.

For example, one can log DOM events' information using the following code:

`javascript
const topic = 'dom-events';
mailbox.subscribe(topic, (_, data) => {
console.log(data);
});
`
