Core Web Vitals

Optimizing for quality of user experience is key to the long-term success of any site on the web. Web Vitals can help you quantify the experience of your site and identify opportunities to improve.


We have optimized the "Onekit" template for easy optimization using the core web vitals. We have optimized various elements to meet the requirements.

Getting Started

Before starting to optimize your website, you need to finalize your design first. If you are just starting out, we suggest you open this documentation. Create a page complete with sections and content. After everything is complete and ready to be uploaded to the server, continue with the optimization on this page. Because service worker are very annoying when trying to work in the devolopment process like editng css or js.

Starter Template

To optimize loading speed, use a template with bundle.min.css and bundle.min.js. You also must activate manifest js, canonical url, meta theme color, apple-touch-icon and Service worker

Complete starter template like following code:

              <!doctype html>
              <html lang="en">
                <!-- Title -->
                <title>Hello, world!</title>

                <!-- Required meta tags -->
                <meta charset="UTF-8">
                <meta http-equiv="X-UA-Compatible" content="IE=edge">
                <meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">

                <!-- Css Optimize -->
                <link rel="stylesheet" href="dist/css/bundle.min.css">

                <!-- PWA Optimize -->
                <link rel="manifest" href="dist/js/pwa/manifest.json">
                <link rel="canonical" href="">
                <meta name="theme-color" content="#5b2be0">
                <link rel="apple-touch-icon" href="dist/img/logo/apple-icon.png">

                <!-- Favicon  -->
                <link rel="icon" href="dist/img/favicon.png">

                <!--Google Fonts-->
                <link href=";500;700&display=swap" rel="stylesheet">

                <h1>Hello, world!</h1>

                <!-- JS Optimize -->
                <script src="dist/js/bundle.min.js"></script>
                <!-- PWA Optimize -->
                if('serviceWorker' in navigator) {
