Hey Guys , Warm Greetings to all , At last you have founded the right blog , regarding's to If you have any doubts regarding the progressive web app pwa and also In this article i provide full guide all about the “How to create progressive web app using basic html and CSS and JavaScript”. So in this tutorial i have covered all this points mentions below
what is pwa ?
Progressive Web Apps (PWAs) are web applications that have the ability to work offline and have native app-like features such as push notifications, home screen icons, and full-screen mode. PWAs are built using web technologies such as HTML, CSS, and JavaScript, but are designed to be faster, more reliable, and provide a more engaging user experience compared to traditional web apps.
One example of a PWA is Twitter Lite, a lightweight version of the popular social media platform that is designed to work well on slow internet connections and low-end devices. The app can be accessed through a web browser on any device, but it also has features like offline support, push notifications, and a home screen icon. This allows users to interact with the app even when they don't have an internet connection and provides a more seamless experience compared to the traditional mobile web version of Twitter.
Another example of a PWA is the AliExpress online shopping app. This PWA provides a fast and reliable shopping experience for users, with features such as offline support for browsing products, push notifications for order updates and sales, and a home screen icon for quick access.
why pwa ? & what is use case ?
PWAs can be installed on a user's device just like a native app, but they don't need to be downloaded from an app store, which makes it more accessible for the users. PWAs are also more easily discoverable through search engines and can be shared via a URL, which makes it easy for users to share with their friends and family.
In summary, PWAs are web apps that provide a native-like experience with offline support, push notifications, home screen icons and other features. With PWAs, developers can create apps that are fast, reliable, and engaging, while also being more accessible and easily discoverable for users.
Use cases for PWAs:
PWAs are ideal for websites that require frequent visits from users. Some of the most common use cases for PWAs include:
- E-commerce websites
- Social media platforms
- News websites
- Online booking websites
Why create a PWA?
PWAs offer several benefits over traditional web apps, such as:
- Offline support
- Faster loading times
- Push notifications
- Home screen icons
- Improved user engagement
- More accessible and discoverable for users
how can we create the pwa ?
A basic Progressive Web App (PWA) can be built using just HTML, CSS, and JavaScript. The core components of a PWA are a web app manifest file and a service worker.
The web app manifest is a JSON file that contains information about the app such as its name, icons, and start URL. It also defines the app's display mode, which can be set to "standalone" to provide a full-screen experience like a native app.
Here is an example of a basic web app manifest file:
//Json_code_here
{
"short_name": "App Name",
"name": "Full App Name",
"icons": [
{
"src": "icon.png",
"sizes": "192x192",
"type": "image/png"
}
],
"start_url": "/index.html",
"display": "standalone"
}
A service worker is a script that runs in the background of the app and enables offline support, push notifications, and other features. It acts as a proxy between the app and the network, allowing the app to function even when the user is offline.
Here is an example of a basic service worker file:
//code_here
self.addEventListener('install', event => {
event.waitUntil(
caches.open('v1').then(cache => {
return cache.addAll([
'/index.html',
'/style.css',
'/script.js'
]);
})
);
});
self.addEventListener('fetch', event => {
event.respondWith(
caches.match(event.request).then(response => {
return response || fetch(event.request);
})
);
});
The above service worker uses the install event
to open a cache and add all the necessary files to it. The
fetch event is used to check the cache for a
matching request before making a network request.
In addition, you need to register the service worker file in your main javascript file. Here is an example:
//code_here
if ('serviceWorker' in navigator) {
window.addEventListener('load', function() {
navigator.serviceWorker.register('/sw.js').then(function(registration) {
}, function(err) {
});
});
}
In the HTML file, you need to link the manifest file in the head section like this:
//code_here <link rel="manifest" href="/manifest.json">
conclusion
These are some basic examples of how to set up a Progressive Web App using HTML, CSS, and JavaScript. Of course, you can add more advanced features and functionalities as per your requirement.
