Matomo Tracker (React Native/Expo)

!Project version

Stand alone library for using Matomo tracking in React Native and Expo projects.

There is one React Native Matomo package mentioned on the official integration docs of Matomo, which sadly cannot be used with Expo because of native modules that are included.

If you know React Native already but have not heard about Expo yet, you can read about it here in their docs.

This package aims for making tracking available in every React Native app with sending custom actions to the Matomo Tracking HTTP API.

There are two existing implementations for Node.js and React, that built the basis for this React Native package. Thanks to:

Installation

``sh


with npm:

npm install matomo-tracker-react-native

or with yarn:

yarn add matomo-tracker-react-native
`

Usage

You need to create a Matomo instance within your project with your specific Matomo details and wrap your app with the MatomoProvider of this package.

The useMatomo hook is exposing all methods you can use for several trackings.

`js
import React, { useEffect } from 'react';
import MatomoTracker, { MatomoProvider, useMatomo } from 'matomo-tracker-react-native';

const MainAppContainer = () => {
const { trackAppStart } = useMatomo();

useEffect(() => {
trackAppStart();
}, []);

return (
Main App
);
};

export const App = () => {
const instance = new MatomoTracker({
urlBase: 'https://LINK.TO.DOMAIN', // required
// trackerUrl: 'https://LINK.TO.DOMAIN/tracking.php', // optional, default value: ${urlBase}matomo.php
siteId: 1, // required, number matching your Matomo project
// userId: 'UID76903202' // optional, default value: undefined.
// disabled: false, // optional, default value: false. Disables all tracking operations if set to true.
// log: false // optional, default value: false. Enables some logs if set to true.
});

return (



);
};
`
