I\'m trying set up Google Analytics on my react site, and have come across a few packages, but none of which has the kind of set up that I have in terms of examples. Was ho

Answer 1

I like how Mark Thomas Müller suggests here:

In your index.js

import ReactGA from 'react-ga'

ReactGA.initialize('YourAnalyticsID')

ReactDOM.render(<App />, document.getElementById('root'))

Where your routes are:

import React, { Component } from 'react'
import { Router, Route } from 'react-router-dom'
import createHistory from 'history/createBrowserHistory'
import ReactGA from 'react-ga'

const history = createHistory()
history.listen(location => {
    ReactGA.set({ page: location.pathname })
    ReactGA.pageview(location.pathname)
})

export default class AppRoutes extends Component {
    componentDidMount() {
        ReactGA.pageview(window.location.pathname)
    }

    render() {
        return (
            <Router history={history}>
                <div>
                    <Route path="/your" component={Your} />
                    <Route path="/pages" component={Pages} />
                    <Route path="/here" component={Here} />
                </div>
            </Router>
        )
    }
}

Short, scalable and simple :)

basic react-ga implementation with your index.js

var ReactGA = require('react-ga'); // require the react-ga module
ReactGA.initialize('Your-UA-ID-HERE'); // add your UA code 

function logPageView() { // add this function to your component
  ReactGA.set({ page: window.location.pathname + window.location.search });
  ReactGA.pageview(window.location.pathname + window.location.search);
}

React.render((
<Router history={createBrowserHistory()} onUpdate={logPageView} > // insert onUpdate props here
    <Route path="/" component={App}>
        <IndexRoute component={Home} onLeave={closeHeader}/>
        <Route path="/about" component={About} onLeave={closeHeader}/>
        <Route path="/gallery" component={Gallery} onLeave={closeHeader}/>
        <Route path="/contact-us" component={Contact} onLeave={closeHeader}>
            <Route path="/contact-us/:service" component={Contact} onLeave={closeHeader}/>
        </Route>
        <Route path="/privacy-policy" component={PrivacyPolicy} onLeave={closeHeader} />
        <Route path="/feedback" component={Feedback} onLeave={closeHeader} />
    </Route>
    <Route path="*" component={NoMatch} onLeave={closeHeader} />
</Router>), document.getElementById('root'));

Answer 3

For dynamically updating url on some event (like onClick etc), following can be used:

 //Imports
 import ReactGA from "react-ga";
 import { createBrowserHistory } from "history";

 // Add following on some event, like onClick (depends on your requirement)
 const history = createBrowserHistory();
 ReactGA.initialize("<Your-UA-ID-HERE>");
 ReactGA.pageview(history.location.pathname);

Answer 4

Based on @david-l-walsh and @bozdoz suggestions

I created a HOC that execute the window.ga('set','page','{currentUrl}) and window.ga('send', 'pageview'); function and is easly used directly in the router page...

this is the HOC:

import React from 'react';
import { history } from '../../store'; // or wherever you createBrowserHistory(); invokation is

function withGAHistoryTrack(WrappedComponent) {
  return class extends React.Component {
    constructor(props) {
      super(props);
    }

    componentDidMount() {
      const { location } = history;
      const page = location.pathname + location.search;

      if (typeof window.ga === 'function') {
        window.ga('set', 'page', page);
        window.ga('send', 'pageview');
      }
    }

    render() {
      return <WrappedComponent {...this.props} />;
    }
  };
}

export default withGAHistoryTrack;

and is used this way in the router page:

<Route
 path={'yourPath'}
 component={withGAHistoryTrack(yourComponent)}
 exact
/>

Since react-router v5.1.0 this can be solved a lot easier with useLocation.

usePageTracking.js

import { useEffect} from "react";
import { useLocation } from "react-router-dom";
import ReactGA from "react-ga";

const usePageTracking = () => {
  const location = useLocation();

  useEffect(() => {
    ReactGA.initialize("UA-000000000-0");
    ReactGA.pageview(location.pathname + location.search);
  }, [location]);
};

export default usePageTracking;

App.js

const App = () => {
  usePageTracking();

  return (...);
};

• https://github.com/react-ga/react-ga/issues/122

Here's a bit smarter version:

usePageTracking.js

import { useEffect, useState } from "react";
import { useLocation } from "react-router-dom";
import ReactGA from "react-ga";

const usePageTracking = () => {
  const location = useLocation();
  const [initialized, setInitialized] = useState(false);

  useEffect(() => {
    if (!window.location.href.includes("localhost")) {
      ReactGA.initialize("UA-000000000-0");
    }
    setInitialized(true);
  }, []);

  useEffect(() => {
    if (initialized) {
      ReactGA.pageview(location.pathname + location.search);
    }
  }, [initialized, location]);
};

export default usePageTracking;

Always go with the library's recommended way

In the React-GA documentation, they have added a community component recommended for using with React Router: https://github.com/react-ga/react-ga/wiki/React-Router-v4-withTracker

Implementation

import withTracker from './withTracker';

ReactDOM.render(
  <Provider store={store}>
    <ConnectedRouter history={history}>
      <Route component={withTracker(App, { /* additional attributes */ } )} />
    </ConnectedRouter>
  </Provider>,
  document.getElementById('root'),
);

Code

import React, { Component, } from "react";
import GoogleAnalytics from "react-ga";

GoogleAnalytics.initialize("UA-0000000-0");

const withTracker = (WrappedComponent, options = {}) => {
  const trackPage = page => {
    GoogleAnalytics.set({
      page,
      ...options,
    });
    GoogleAnalytics.pageview(page);
  };

  // eslint-disable-next-line
  const HOC = class extends Component {
    componentDidMount() {
      // eslint-disable-next-line
      const page = this.props.location.pathname + this.props.location.search;
      trackPage(page);
    }

    componentDidUpdate(prevProps) {
      const currentPage =
        prevProps.location.pathname + prevProps.location.search;
      const nextPage =
        this.props.location.pathname + this.props.location.search;

      if (currentPage !== nextPage) {
        trackPage(nextPage);
      }
    }

    render() {
      return <WrappedComponent {...this.props} />;
    }
  };

  return HOC;
};

export default withTracker;
