Introduction to PWA || Learn the core concept of PWA and its features

A Progressive Web App is a type of web application which can be used as a web page and mobile app on any given device.  PWAs are about using web technologies to mimic the best features of native apps: speed, connectivity independence, data synchronization, and use on any type of device.

The general idea of Progressive Web Apps is quite easy to display. They are apps written in web technologies (JavaScript, CSS, HTML) that look and behave just like regular web pages. They are visible in Search Engine Page Results and linkable, but offer similar functionalities to native mobile apps: they work offline, can send push notifications and use device hardware the same way as native apps.

Types of Mobile Apps

Web app

A Web application can be defined as an application that can be accessed through the Internet using a Web browser. or we can say A Web application (Web app) is an application program that is stored on a remote server and delivered over the Internet through a browser interface.

Advantages Of Web Apps

A web application is a Cross Platform, Highly Discoverable application user can easily access any web application using any type of device like . Mobile, Tablet, Laptop. etc using any type of web browsers. and its easy to develop process

Disadvantage of Web Apps

Some point of view web apps is not good like Slow Performance, low integration, poor reliability and Poor user engagement.

Native Apps

Native apps are programs designed to run on mobile devices such as smartphones or tablets. Mobile apps can be downloaded through mobile app stores.

Advantages Of Native Apps

it’s come with a Good user experience, High performance and its provide some advance functionality like High Integration, High Reliability and High User Engagement.

Disadvantage of Native Apps

for developing native apps developer should learn different technology for different devices like if developer wants to develop application for android device then they should learn about java or Kotlin like programming. if developer wants to develop application for iOS device then they should learn about Swift like programming. it Means native application development process is costly. and some high functionality native apps take large space in device it also decrease the device performance.

Hybrid App

A (hybrid app) is a software application that combines elements of both native apps and web applications. Hybrid apps are essentially web apps that have been put in a native app shell. Once they are downloaded from an app store and installed locally, the shell is able to connect to whatever capabilities the mobile platform provides through a browser that’s embedded in the app. The browser and its plug-ins run on the back end and are invisible to the end user.

Advantages of Hybrid Apps

its a cross platform application and easy to develop process we can use some Modern frameworks like cordova, PhoneGap. etc and can easily build(covert web apps to Mobile apps)

Disadvantage of Hybrid apps

Hybrid apps run on Web View its not performing like a native app. hybrid apps have a design that doesn’t have a native feel. The user interface thus isn’t as seamless.

Each platform, iOS or Android, has unique capacities that a developer may wish to exploit. If this is the case, a combination of specific plugins and code of the platform will be used to achieve this on a hybrid app.

Progressive Web Apps

Progressive Web Apps are the modern application which get all the good features from the web application and native application. and perform good in all type of devices. Progressive Web Apps, introduced by Google, eagerly approved by Microsoft and reluctantly adopted by Apple, are gaining massive popularity among global leaders of online technologies. Companies such as Twitter, flipkart, Pinterest, Trivago, OLX and Forbes, which have already field-tested the abilities of PWA technology to boost user engagement, proved that it is the best answer to the challenges of the mobile world.
