Push Configuration

To enable push notifications for every page of your website, follow the steps below:
Locate the service_worker.js file in your website project. If it doesn't exist, create a new file.
Move the service_worker.js file to your web server's root > public > apps > contlo directory.
Add the following code to the service_worker.js file:
"use strict";

async function postData(url = '', data = {}) {
    const response = await fetch(url, {
        method: 'POST',
        headers: {
            'Content-Type': 'application/json'
        },
        body: JSON.stringify(data)
    });
    return response.json(); // parses JSON response into native JavaScript objects
}

self.addEventListener('install', function (event) {
    event.waitUntil(self.skipWaiting()); //will install the service worker
});

self.addEventListener('activate', function (event) {
    event.waitUntil(self.clients.claim()); //will activate the serviceworker
});

// Register event listener for the 'notificationclick' event.
self.addEventListener('notificationclick', function (event) {
    const clickedNotification = event.notification;
    event.notification.close();
    var redirectUrl = null;
    if (event.notification.data) {
        redirectUrl = event.notification.data ? event.notification.data.url : null
    }

    if (event.action.includes("action0")) {
        redirectUrl = event.notification.data ? event.notification.data.actions[0].link : null
    } else if (event.action.includes("action1")) {
        redirectUrl = event.notification.data ? event.notification.data.actions[1].link : null
    }

    console.log("notificationclick url1:" + redirectUrl)
    event.waitUntil(
        clients.matchAll({
            type: "window"
        }).then(function (clientList) {
            if (clients.openWindow) {
                return clients.openWindow(redirectUrl);
            }
        })
    );
    sendClickEvent(event.notification.data)
});

self.addEventListener('notificationclose', function (event) {
    if (event.notification.data) {
        let payload = event.notification.data
        postData(payload.close_acknowledge_url, {short_url: payload.url})
            .then(data => {
                console.log('close_acknowledge_url success');
            });
    }
});


function sendClickEvent(payload) {
    postData(payload.click_acknowledge_url, {short_url: payload.url})
        .then(data => {
            console.log('click_acknowledge_url success');
        });
}

function sendViewEvent(payload) {
    postData(payload.open_acknowledge_url, {short_url: payload.url})
        .then(data => {
            console.log('open_acknowledge_url success');
        });
}

self.addEventListener('push', function (event) {
    var payload = event.data ? JSON.parse(event.data.text()) : {};
    console.log("event_data", payload);

    let actions = []
    if (payload.actions) {
        for (let i = 0; i < payload.actions.length; i++) {
            if(payload.actions[i].title !== "" && payload.actions[i].title !== null && typeof payload.actions[i].title !== 'undefined') {
                actions.push({action: "action" + i, title: payload.actions[i].title})
            }
        }
    }

    sendViewEvent(payload)
    let showNotification = self.registration.showNotification(payload.title, {
        title: payload.title,
        body: payload.body,
        icon: payload.icon,
        url: payload.url,
        actions: actions,
        image: payload.image,
        tag: payload.url + payload.body + payload.icon + payload.title,
        data: payload,
        requireInteraction: true
    });
    event.waitUntil(showNotification);
});
