Updated Date: November 20, 2023
Written by Hemendra Singh

In the modern era of smartphones, creating a mobile-friendly application has become an essential factor for any business. Progressive Web Apps (PWA) have emerged as a powerful alternative to native mobile applications that offer several advantages to both users and developers. In this blog, we will guide you on how to create a PWA that can take your business to the next level.

A PWA is a website that can be accessed from any device and provides an experience similar to that of a native mobile application. It can be installed on the user’s device without visiting an app store, and it loads faster, even on slow network connections. PWA is built using web technologies such as HTML, CSS, and JavaScript, and it is designed to be responsive, reliable, and engaging.

According to recent statistics, PWAs are growing at a rapid pace, and it is estimated that by 2025, they will account for around 28% of all app downloads. In addition, PWAs are known to increase user engagement, with users spending up to 8x more time on them than on traditional mobile websites. This means that if you want to expand your customer base and improve user experience, PWA is an excellent choice.

However, creating a PWA can be challenging, especially if you are not a developer. Therefore, it is recommended to seek the services of a PWA development company that can help you build progressive web apps that meet your specific requirements. The cost to create a PWA varies based on several factors, such as the complexity of the project, the features required, and the time required to complete the development. Nevertheless, the cost of building a PWA is significantly lower than developing a native mobile application, making it an affordable solution for small and medium-sized businesses.

In conclusion, the world is moving towards mobile-first solutions, and PWA is a great way to stay ahead of the competition. By following the steps and guidance provided in this blog, you can create a PWA that provides an engaging and seamless user experience.

What is (PWA) Progressive Web App?

what is pwa
PWA is a service developed from web technology that our web app development as a whole knows and loves, similar to HTML, CSS, and JavaScript, yet with a vibe and usefulness that matches an actual native application. The catch here is that, with two or three savvy augmentations, you can transform practically any site into a progressive web application.

This implies that the developers can create progressive web apps rather rapidly concerning a native application that is hard to create. Besides, you can offer every one of the highlights of local applications, similar to push warnings, disconnected help, and significantly more.

Many of the websites you visit online are progressive web apps (PWA). Consider Twitter, which is currently the most popular social media platform. You may add twitter.com to your phone’s main screen by accessing the website on your smartphone. When you access the saved Twitter site, you’ll see that it appears and behaves almost like a local application.

There isn’t even a program window. It doesn’t matter if you’re using an iPhone or an Android phone to run it. Many of the websites you visit online are progressive web apps (PWA). Consider Twitter, which is currently the most popular social media platform.

When comparing the features and range of platform-specific applications versus web apps, platform-specific applications represent the highest capabilities, while web apps obtain the optimal reach. So, how do Progressive Web Apps fit into the picture?

Progressive Web Apps (PWAs) use current APIs to provide greater functionality, dependability, and installability while addressing anybody, anytime, on any platform with a single source code.

In other words, it is a new type of communication with the target demographic that is carried out via internet technology and requires little effort on behalf of the user. Some key features associated with PWA services are mentioned below:

  • More than 80% of mobile phone users do not install a smartphone application for more than a month.
  • Companies who migrate to PWA see a 20% to 250% boost in conversion rates, which is a substantial difference that generally correlates to more significant income for enterprises.
  • As compared to their native counterparts, progressive web apps require 33% less upkeep.
  • It’s also worth noting that progressive web apps have a low bounce rate of only 42.86 percent. In comparison, the average smartphone bounce rate is over 60%, the same for tablets is around 49%, and the same for desktop ranges between 41% and 55%.

Progressive web applications, which allow users to browse their preferred website from their phone in a seamless and pleasant manner, are unsurprisingly more engaging. And, in the long term, generate more money for enterprises.

Users of PWAs can install apps right away. In addition, it is possible to set up automatic updates. A functional offline option allows you to access the site without relying on push notifications, which makes it even more convenient.

Components to Create Progressive Web Apps

You should become familiar with the layout and main components to create a PWA to better understand it.

1. Service Worker

It’s a JavaScript file that runs on its own, independent of the web page or application. It is responsible for PWAs’ fundamental functioning, but its most important feature is its capacity to manage data traffic. To put it another way, it is in charge of response caching. Furthermore, background synchronization is handled by this function, which runs in the background of users’ browsers.

2. Application Shell

A PWA’s app shell is another essential component. It allows for quick functioning. In simple words, it is a type of content container. This module does not require a lot of code and has essential elements like the header and navigation menu. Each time a PWA is launched, the application shell is not loaded. Instead, it is cached once and displayed to users who do not have access to the Internet. It’s worth mentioning that the app shell becomes critical for online apps with frequently updated information but static navigation.

3. Web App Manifest

The primary features of a progressive web application are specified in this JSON file, including the app description, short name, theme color, launch style, display, orientation, etc. In addition, the web app manifest file may be customized to include a collection of icons in different sizes for the “add to home screen” function.

4. Push Notifications

This tool might be helpful if your present level of consumer engagement is low. These communications are only delivered to those who have explicitly consented to accept them. You may use them to stay in touch with your consumers and keep them informed about specials, promotional deals, new inventory, and other information.

Technologies to Build a PWA

The following programming languages, PWA frameworks, and tools are the best options to create a progressive web app.

1. React.Js

Due to various frameworks and technologies that simplify and speed up the PWA app development process, developers utilize React.js to construct the front-end section of the application.

2. Ruby and Ruby on Rails

Rail is a versatile framework with ready-to-use components that allows us to create correct back-end logic.

3. Service Worker API

It gives us the ability to convert a static website into a progressive web application.

4. SCSS/CSS-in-JS/Modular Stylesheets

Developers will find this helpful while designing and decorating Web pages.

There are several advanced web app development tools and processes available to assist developers in creating high-quality PWAs. You might be interested to learn how to develop blazor PWA?

Benefits of Creating a PWA (Progressive Web App)

benefits of build a PWA
Progressive Online Apps (POAs) are web applications that have been designed to be strong, trustworthy, and simple to use. The benefits of building PWA functionalities are enormous for a minimal amount of effort. Consider the following scenario:

1. Responsive to any Screen Size

Because various devices have varied screen widths, consumers will use your app on a variety of platforms. As a result, it’s an excellent way to ensure your program works on any screen resolution and that its content is accessible regardless of viewport size.

2. Easy to Install

Users who download applications are more likely to use them. It offers PWAs the appearance, feels, and behavior of a traditional web app by making them easily installable.

3. Responsive Irrespective of Internet Connectivity

Keeping users in your app instead of redirecting them to a preset offline page delivers a more seamless experience when a user is offline.

Travel and hospitality applications, for example, should be able to display trip data even when they are not connected to the Internet. Another example is a music app, which should allow users to listen to music when offline.

4. Quickly Found Via a Search Engine

Search engines like Google help users find their websites and apps on the web. If your app has a PWA, it can help drive visitors to it. All you have to do now is make sure the URLs are correct, and that search engines can index your pages.

5. Compatible with Multiple Browsers

PWAs are first and foremost web applications, which means they must operate across all browsers, not just a few. Therefore, before users opt to install applications, they should leverage them in any browser.

6. PWAs Work with Several Input Modalities

A multitude of input techniques is available on multiple devices. As a result, a PWA should work with a mouse, keyboard, or touch screen. While using your application, users should be able to switch between multiple input devices. You should ensure that your program and its features are compatible with whatever input methods a user could pick.

We’ve learned what Progressive Web Apps are and what constitutes a good one. However, we discussed Native Apps previously. So what’s the distinction between the two?

PWA Vs Native Apps: Key Differences

progressive web apps vs native apps
A progressive web app is a web application that aims to provide a smooth, native-like user experience. PWAs run in the browser, but native mobile apps must be installed from an application store. The main difference between these two types of software is that one emphasizes utility while the other emphasizes style.

Users’ information is saved in the cache when they use advanced web applications. Users will be able to accomplish this if we provide them the option to stay updated at all times, regardless of their Internet speed.

What enables Progressive web apps to operate is that they contain URLs, allowing Google to index them. Thus, users can quickly discover them using a search engine. PWAs can even be utilized when the user is not connected to the Internet. Another benefit is that the cost of developing a progressive web app is less than that of creating a native app. This guide will help you to deep understanding of the PWA Vs Native Apps.

Furthermore, the process of developing a progressive web app is easier and more efficient. For both platforms, building native apps from the ground up necessitates diverse and particular technologies.

So far, we’ve discussed why you should use a PWA. However, we haven’t discussed how to begin constructing them. So, here’s what you’re going to need.

Key Factors that Affect the Cost to Build a PWA

cost to build a PWA
The price of PWA development services is a complex subject to answer. The reality is that no two projects are the same, as much relies on the sophistication of your website. In addition, the PWA development company’s methodologies, technology, and subject knowledge varied, as did the pricing.

However, one thing is clear for every website: the more complicated it is, the longer it will take a progressive web applications development business to design a PWA. Naturally, therefore, the higher the price will be.

The primary elements determining overall expenditure on developing a progressive web application are listed below.

1. PWA Project Size

The scope of your business mainly determines the cost of developing an app. A tiny venture requires less time for development. As a result, such initiatives are less expensive. However, more significant projects will almost certainly need additional team members, time, and money.
It is often easier to discover and correct issues with small projects. However, large ones can be confusing, and redesigning some program elements or fixing bugs requires more work and energy.

2. PWA Project Complexity

The project’s complexity also determines the cost of developing a progressive web application. The more complicated something is, the more it costs. In most cases, complex projects necessitate the use of experienced and competent designers and developers. Unfortunately, such teams are not available in every company.

3. Technical Features to Create Progressive Web App

Of course, the cost of developing an app is determined by the number of distinct features you wish to include. The more functions you want to add, and the more intricate they are, the more you’ll have to spend.

This aspect is inextricably linked to the project’s complexity. You’ll need a team of experts with a lot of expertise in building many kinds of web apps, including PWAs. Companies that wish to give their consumers more complex options frequently have to pay more. Additional features are required to improve brand identification, client loyalty, and other aspects of the business.

The web application pricing will be minimal if you want a typical application with a simple set of functionality. The cost of progressive web app development is also determined by the features you want in your application.

4. Country of the Contractor

The contractor’s place of origin also determines the cost of a progressive web app. One of the most essential and intriguing aspects determining the cost of developing an application is the contractor’s nation. Depending on your contractor’s location, you may pay anything from $200,000 to $50,000 for the identical solution.

The company’s local market will always determine the final cost of the PWA. As a result, if you ask Swiss or American web professionals about the typical cost of developing a website, they will tell you the most expensive alternative. In contrast, Professionals from Indonesia or India will ask for a much cheaper quotation.

When it comes to developing progressive web apps, a high cost does not always reflect a high level of quality. This becomes clear when you examine the prices of employing teams from all across the world.

The cost of developing a progressive web app varies based on where you are. Let’s look at the numbers in more detail.

Countries Salary Range/ hour
USA and Canada $60-150
Australian $50-120
South-American $20-110
United Kingdom $40-160
India $10-75
Indonesia $20

5. Experience of the Contractor

Of course, the cost of developing a web application is impacted by the contractor’s experience and the region in which they’re based. There’s nothing complex about this. The higher the cost of the job, the more experienced your contractor is.

When assessing expertise, consider the number of years spent working in the sector, samples of previously built apps, customer feedback, and so on. However, don’t presume that successful businesses would overcharge you. Many good web design and development businesses, for example, in Eastern Europe, provide low pricing while producing exceptional and quality work.

6. Collaboration Model

The collaboration model is the final component that determines the cost of a progressive web app. Fixed pricing and time and material (T&M) models are the two sorts of approaches.

The client pays the consultant for the outcome at a predetermined cost and terms of work under a fixed pricing model. The scope of the project and deadlines are accurately estimated, and the principal focus is to deliver on time and stick to the budget. Performance and quality may suffer under this strategy to satisfy budget and timelines.

The key benefit of this arrangement is that the price is known and determined in advance. However, during the development process, you will not be able to make any significant changes, entirely modify the application idea, or add parts. In addition, the expert rate in this model is typically 15-20% higher than the Time & Material rate.

According to the specialists ‘ real working time, the consumer pays for the procedure, i.e., under the Time & Material model. The scope of work and implementation time are estimated roughly, and the most critical factor is the outcome and quality. For more outstanding results or quality, time and expense may be increased.

You will be allowed to make adjustments throughout product innovation using this plan, but you will have to pay more money. Therefore, it is critical to prioritize and set a budget when picking one of these two methods.
