With the advent of technology and easy internet access, smartphones have gained a lot of popularity. Most of the time, we are glued to our applications. Today, we will talk about the top Progressive Web App Framework in detail.

In these torrid times, it has really become important for the small business to reach the customers and the easiest way to connect with them is by using mobile applications. 

It is the best channel to reach to the customers and inform them about your products as well as any offers you are rolling out. The Cost To Make A Website is not low as well.

In recent times, it has served as the best marketing tool which can be used to reach new potential customers and connect with them directly. Recently, progressive web applications (PWA) have emerged which provide users with a native experience and do not require them to install applications. 

What is Progressive Web Application PWA?

Progressive Web Application extracts the best out of native web applications and Web Apps. Progressive Web applications are built with modern APIs to deliver native experience and they can be used to connect with all users similar to Web Apps. 

In progressive web apps, modern capabilities are added to the browser, and web manifest allows your application to be reliable and installable. 

Twitter has reported a 65% increase in pages per session and 75% more tweet, after moving to progressive web apps. Similarly, Nikkei observed 58% more subscriptions and also saw an increase in inactive users.   

Benefits of Progressive Web Application

  • Compared to the basic Web application, PWA tends to be more engaging to customers because of their native UI and capabilities.
  • It is promoted by tech giants like Microsoft and Google. Google has made enhancements to their browser and they accept these applications to be listed in google play. Even Microsoft allows you to list your Progressive Web applications in their store.
  • PWAs are used by tech companies such as Instagram, Twitter, Uber, and other leading companies. 
  • Progressive Web applications are lightweight and can be installed quickly as compared to native applications. Their load time is also fast. 
  • PWAs use HTTPS protocol so they are safe from the moment you start building applications using it. 
  • PWAs typically take less time to build and can be quickly shipped to the market. If the developer is familiar with building a web application, he can easily build Progressive Web applications. You can even use components from your existing Web applications. 

Disadvantages of Progressive Web Application

Every good thing mostly comes with some issues. 

  • The major issue is the reluctance of Apple towards the Progressive Web application. With iOS 11, you can develop PWA for iPhone, but it is limited.
  • Progressive Web applications are based on the Safari browser and the browser is not natively able to support multiple functionalities of Progressive Web applications. For instance, it only allows you to store 50mb of data in device memory. 
  • Also, in iOS, you cannot install native applications that are not listed in the official App store and as a result of this  your customer reach will also decrease.

10 Noteworthy PWA Framework

React

React is an open-source project which is developed and maintained by Facebook. There are many JavaScript libraries available in React which you can use to build Progressive Web Applications. So, it’s a top-class Progressive Web App Framework.

It is one of the most used frameworks for building frontends. It can be used to develop both single-page applications as well as multi-page applications. React uses Virtual DOM so that application rendering is fast and seamless. 

React allows you to create components using JSX and these components can be reused across different web applications. You can even open-source the complete component which can be used by various other teams. 

Benefits of React

  • Open source and active community help you if you are stuck

  • There are issues when you try to build complex components. 
  • The code is not standardized so it becomes difficult to manage complex projects.

Angular

Angular was created by Google in 2010 and is the most mature and widely used framework to build web applications. It is packaged with most of the functionalities that are needed to build a web application. 

In 2017, Angular 5 was the first version to support Progressive Web Application.  

It added a dedicated service worker script, which allows you to create progressive web applications, by using JSON configuration. 

This allowed developers with less expertise also to create web applications with ease.

Svelte is a relatively new PWA Framework to build web applications. 

It has gained a lot of popularity recently and is adopted by various companies such as GoDaddy and The New York Times. 

Svelte is inspired by React and Vue and it tries to solve shortcomings that are present in React.

Svelte tries to shift a lot of code from run time, where the virtual DOM gets updated, to compile time. Instead of virtual DOM, Svelte updates the variables precisely as the state changes. 

This optimization at compile time allows you to build complex applications and the speed of the application has also improved drastically. 

With version 3 released in the market, you can now easily write components. All the boilerplate code typically used to write a component is baked in the framework itself. Svelte framework aim is to be completely reactive. 

Benefits of Svelte

  • You need to write less code as compared to other frameworks
  • There is no virtual DOM 
  • It is designed to be truly reactive

Disadvantages of Svelte

  • It does not give you as much freedom as React does. 
  • Components give less visual feedback
  • The community is small, and the support is limited
  • It lacks tooling

Why Choosing the Right PWA Framework Is Essential?

When you start building a PWA, it is really important to choose the right framework to start with. There are various factors which will allow you to choose the right framework. 

It is important to choose a framework that can help you support all the complex components which you want to build. 

You can also consider the size and performance the framework will provide so that you have a small and seamless application.

One of the major factors is to consider your team’s expertise. You should choose a framework in which your team is comfortable and has previously worked on it. Also, you should consider the maturity of the framework while choosing a project. 

One more thing to keep in mind is the fact that you really need PWA. If your website experience has a lot of navigation between pages, it might not be a good idea to build a PWA. It will degrade your experience and lead you with zero value.
