Install

At first install MixvisitJS package

# with npm package manager
npm install @mix-visit/lite

# with yarn package manager
yarn add @mix-visit/lite

# with pnpm package manager
pnpm add @mix-visit/lite

Usage

After installation, you can use the module. Import the main MixVisit class and the ClientData type.

import { MixVisit, type ClientData } from '@mix-visit/lite';

First, create an instance of MixVisit for usage.

const mixvisit = new MixVisit();

For example, collect all data except geolocation, with a timeout of 700 ms for asynchronous parameters. Then, use get method to retrieve all collected client data and save it in the data variable.

await mixvisit.load({ exclude: ['geolocation'], timeout: 700 });
const data: ClientData = mixvisit.get();

Suppose that after we need this geolocation parameter, we also need the webrtc parameter that was not loaded due to a timeout. The load method with the only option executes with a maximum timeout of 12 seconds. This option loads only the specified parameters. After that, when requesting all data, the geolocation and webrtc parameters will be included.

await mixvisit.load({ only: ['geolocation', 'webrtc'] });
const extendedData = mixvisit.get();

After you have loaded the parameters using the load method, the properties loadTime and fingerprintHash become available. The loadTime property stores the time of the last load function execution. The fingerprintHash property contains the generated fingerprint hash.

const loadTime = mixvisit.loadTime;
const hash = mixvisit.fingerprintHash;

You can also retrieve the loaded parameters using the get() method. If you want to retrieve all client data, call the get() method without options. If you need a specific parameter, pass its name as a string. To get multiple parameters, provide an array with the required parameters.

const allClientData = mixvisit.get();
const isDevToolsOpen = mixvisit.get('devToolsOpen');
const { location, geolocation, webrtc } = mixvisit.get(['location', 'geolocation', 'webrtc']);
