User-behavior-tracker is a plugin that allows you to track and log user behavior in the browser environment.
Track the user's keyboard input, page navigation, text dragging, tab exit, tab return, window exit, window return, and image viewing.
-
When tracking user behavior, it should not affect the performance of your application.
Internally, it uses requestIdleCallback to handle user events asynchronously, so it doesn't adversely affect performance.
For browsers that do not support requestIdleCallback API (ex. safari, IOS safari), polyfill is supported. -
Event handlers are not added to all elements on the screen.
The event handlers required for tracking are added to the root element, so there is no need to add event handlers every time the screen is switched. There is no performance hit caused by event bubbling.
In your local directory, enter the command below
$ yarn buildthen, you can see the dist directory.
If you want to use it in esm format
import { track } from '../dist/esm';
track(document.getElementById('root'), (log) => {
// some tasks...
});If you want to use it in the script tag
<script src="../dist/bundle.js"></script>In your local directory, enter the command below
$ yarn build
$ yarn demothen, access http://localhost:1234 through your browser.
