Prezly Analytics for Next.js

This library is an easy plug-and-play solution to enable Prezly Analytics on your website or application. It is based on analytics-next by Segment, and is basically a wrapper around the library, which allows you to use both Segment analytics and Prezly analytics with little to no boilerplate. The API for tracking calls remains unchanged from analytics-next, so you can refer to its documentation for any additional Segment features you want to use in your project.

Features

• 🔁 Seamless integration with Segment Analytics
• 🤖 Automatically handles Segment and Google Analytics integrations on your Prezly Newsroom
• 🔒 GDPR-compliant tracking
• 🚀 Coming soon: 1st party domain tracking support

Adding the library to your application

npm

npm install --save @prezly/analytics-nextjs

Install into your Next.js application

/pages/_app.tsx

First you need to create a global analytics instance:

import { Analytics } from '@prezly/analytics-nextjs';

export const analytics = new Analytics();

Next you need to initialize analytics. In Prezly websites we do it in useEffect, when we have all the required settings loaded.

analytics.init({
    consent,
    trackingPolicy,
    segment: {
        settings: {
            writeKey: segmentWriteKey,
        },
    },
    plausible: {
        domain: 'plausible domain',
    },
    google: { analyticsId: googleAnalyticsId },
});

If you want to disable Segment, Plausible or Google tracking, just set their settings to false.

To keep the example simple, we omit the code that actually fetches these props, since that can depend on your particular implementation. You can check how it's implemented in Prezly Bea Theme utilising our Next.js Theme Kit.

Enabling automatic page tracking

In order to enable the base tracking for page visits and campaign asset clicks, you should place Tracking component anywhere in your component tree. The best place to do it is in a custom Layout component.

import { Tracking } from '@prezly/analytics-nextjs';
import type { PropsWithChildren } from 'react';

import { analytics } from '@/lib/analytics';

interface Props {}

function Layout({ children }: PropsWithChildren<Props>) {
    return (
        <>
            <Tracking analytics={analytics} />
            <main className="customLayout">{children}</main>
        </>
    );
}
export default Layout;

Here's what this component does for you:

• Automatic page visit tracking
• Detecting Campaign recipients and firing Campaign Click events
• Auto-clicking assets linked from a Campaign when used with Prezly Content React Renderer

Tracking additional events

Tracking events to Prezly is pretty simple: you need to import the desired event group (STORY_LINK in this example), and pass it to the track() call.

import { STORY_LINK, useAnalytics } from '@prezly/analytics-nextjs';
import type { PropsWithChildren } from 'react';

import { analytics } from '@/lib/analytics';

import styles from './styles.module.scss';

interface Props {
    href: string;
}

export function Link({ href, children }: PropsWithChildren<Props>) {
    function handleClick() {
        analytics.track(STORY_LINK.CLICK, { href });
    }

    return (
        <a href={href} onClick={handleClick}>
            {children}
        </a>
    );
}

Tracking to Prezly is done through Segment plugin. This is done for getting event object enriched by Segment. Prezly analytics require newsroom property to be set in meta object.

analytics.setMeta({ newsroom: 'newsroom uuid' });

You can find more examples of tracking calls in the Prezly Bea Theme repo.

Cookie consent

You can now pass user cookie consent as a consent prop to AnalyticsProvider. Consent may include following categories:

• first-party-analytics - Allows Prezly and Plausible tracking
• third-party-cookies - Is a superset of first-party-analytics and also allows Google Analytics
