Progressive Web Apps (PWAs) are apps created using web technologies that we are all familiar with and enjoy, such as HTML, CSS, and JavaScript.
PWAs are designed with features such as Push Notifications and the ability to work offline.
They are also built on and enhanced with modern APIs, making it simple to provide enhanced capabilities as well as reliability and the ability to install them on any device.
PWAs benefit from the vast web ecosystem, which includes plugins and a community, as well as the relative ease of deploying and maintaining a website, as opposed to a native application, which is quite difficult to develop.
This means you can quickly and easily create a PWA.
Many companies have shifted into the product due to its popularity, which I believe is due to its ability to run on both Android and iOS without much difference.
Top companies that have PWAs for their products include Twitter, Pinterest, Uber, Tiktok, Spotify, and others.
The internet is a fantastic platform.
Due to its widespread use across platforms and operating systems, user-centered security model, and lack of corporate control over either its specification or its implementation, the web is a special platform for software development.
When combined with its inherent linkability, you can search it and share what you find with anyone, anywhere.
When you visit a website, it is current, and your interaction with that site can be as brief or as long as you want.
With a single codebase, web applications can reach anyone, anywhere, and on any device.
Platform-specific applications are well-known for their richness and dependability.
They can be found on home screens, docks, and taskbars. They function regardless of network connectivity.
They begin in their own separate experience.
They can read and write files from the local file system, connect to hardware via USB, serial port, or Bluetooth, and even interact with data on your device, such as contacts and calendar events.
You can use these apps to take pictures, see which songs are playing on the home screen, and control song playback while in another app.
Platform-specific applications have the appearance of being a part of the device on which they run.
Progressive Web Apps (PWA) are created and enhanced with modern APIs to provide enhanced capabilities, reliability, and installability while reaching anyone, anywhere, and on any device with a single codebase.
The Three Most Important PWA App Pillars
Progressive Web Apps are web applications that are capable, dependable, and installable.
They become a platform-specific application-like experience when these three pillars are present.
Capable
Today’s web is quite capable in its own right.
You can, for example, use WebRTC, geolocation, and push notifications to create a hyper-local video chat app.
You can install that app and make its conversations virtual using WebGL and WebVR.
Developers can now tap into other ecosystems, such as C, C++, and Rust, and bring decades of work and capabilities to the web, thanks to the introduction of WebAssembly.
Only platform-specific apps could truly claim these features.
While some capabilities remain out of reach for the web, new and upcoming APIs are aiming to change that by adding features like file system access, media controls, app badging, and full clipboard support.
All of these features are built on the web’s secure, user-centric permission model, ensuring that visiting a website is never frightening for users.
Web applications are more capable than ever, thanks to modern APIs, WebAssembly, and new and upcoming APIs, and those capabilities are only growing.
Reliable
Regardless of the network, a dependable Progressive Web App feels fast and dependable.
Users must be able to use your experience quickly.
In fact, as page load times increase from one to ten seconds, the likelihood of a user bouncing increases by 100%.
Scrolling and animation should be fluid. The entire user experience is affected by performance, from how they perceive your application to how it actually performs.
Applications that are reliable must be usable regardless of network connection. Users expect apps to launch even when their network connection is slow or unstable, or even when they are offline.
They expect the most recent content with which they have interacted, such as media tracks, tickets, and itineraries, to be available and usable even if getting a request to your server is difficult.
When a request isn’t possible, they expect to be informed rather than silently failing or crashing.
Users deserve apps that respond to interactions in the blink of an eye, as well as a dependable experience.
Installable
Installed Progressive Web Apps run in a separate window rather than a browser tab.
They can be accessed from the user’s home screen, dock, taskbar, or shelf. It is possible to search for them on a device and switch between them using the app switcher, making them feel like they are a part of the device on which they are installed.
After installing a web app, new capabilities become available.
Keyboard shortcuts, which are normally reserved when using a browser, become available.
Progressive Web Apps can be configured to accept content from other applications or to be the default application for handling various file types.
When a Progressive Web App transitions from a tab to a standalone app window, it changes how users perceive and interact with it.
Progressive Web Apps give you a one-of-a-kind opportunity to provide a web experience that your users will love.
Progressive Web Apps, which use the latest web features to improve capabilities and reliability, allow what you build to be installed by anyone, anywhere, on any device using a single codebase.
Advantages of PWAs
Many organisations, both private and public, are shifting to PWAs, not only because they are less expensive to develop, but also because they provide greater engagement.
A summary of the advantages of a PWA:
Adaptable to a variety of screen sizes and responsive.
Work in the same way as regular Native Apps.
The updates are self-contained; you do not need to visit the Play Store to get one.
Built using standard web technologies.
Lightweight and quick.
Unlike other websites, this one works offline.
Searchable via a search engine.
Simple to set up.
Low operating costs.
Frameworks for Developing Progressive Web Apps
PWA is the result of a novel cross-platform app development methodology that uses the mobile browser to deliver web pages installed on your phone.
It is a hybrid of a native app and a mobile website that delivers an app-like user experience by utilising standard web technologies such as CSS, HTML, and JavaScript.
PWAs provide a faster loading experience, can function offline, and are search engine discoverable.
They are the reason why certain brands, such as Alibaba, Trivago, and Twitter, provide a seamless mobile browsing experience.
The best frameworks for PWA development
AngularJS
After you get past the steep learning curve, Angular is a fantastic framework to work on.
It’s completely modular, with each Angular element fully compatible with projects built with other frameworks.
The entire development process with Angular is also simplified because it is designed to eliminate the hassle of dealing with monotonous, repetitive tasks.
Angular’s proprietary compilation technique, Ahead of Time (AOT), which enables quicker application rendering by converting Angular HTML and TypeScript code into effective JavaScript code before the browser downloads and runs the app, is another significant advantage for Progressive Web Apps built with Angular.
Pros:
Methodology that is well-planned
A large and active developer community
Infrastructure that is complex and suitable for large-scale projects
A fantastic collection of third-party extensions to choose from.
Optimized for speed and security, with a brilliant and unique concept – ‘ahead of time compiler’
Injecting dependencies into code to increase modularity and efficiency
Elements that are completely modular
Cons:
TypeScript knowledge is required.
The learning curve is steep.
Not search engine friendly
ReactJS
React, which was released by Facebook in 2013, is a popular choice among developers due to its extensive JavaScript library.
The Progressive Web App development framework can create single-page and multi-page apps, with the content loading and changing on a single page.
It employs JSX to render functions for connecting HTML structures, resulting in a React PWA solution.
Pros
PWAs powered by React have greater flexibility and can be scaled with additional packages.
Developers can use the same code to create native apps.
Because of Virtual DOM, the rendering process is quick.
The Progressive Web App development framework generates API interactions, server-side and static rendered pages, and routing by utilising various JavaScript libraries.
Cons
Aside from JavaScript, the React PWA solution requires knowledge of JSX.
The lack of a clearly defined methodology makes implementation difficult.
Because of the presence of JSX, migration from AngularJS is difficult.
The more flexibility you seek, the more functionality issues will arise in the React PWA solution.
VueJS
Vue is an open-source JavaScript front-end framework distributed under the MIT licence.
Vue is simple to use and is primarily driven by the community.
For starters, features like routing, high-speed rendering, and simple coding can help you streamline the development process.
VueJS and ReactJS have many similarities at their core, as both use Virtual DOM for a lightweight and efficient representation of the actual DOM.
Vue embraces and improves on existing web technologies like HTML and CSS, whereas React takes a more advanced approach that primarily uses JavaScript.
It’s also because of this that frontend beginners may find it easier to learn and develop PWA in Vue, making the Vue learning curve more forgiving for newcomers.
Pros:
Most simple to grasp
Good documentation
To achieve the best results, it can be combined with JSX and Typescript.
Animations
Virtual-DOM improves rendering performance Cons:
Too adaptable: In large projects, there are far too many reported and unresolved integration issues.
Small development group
Preact
Preact is a lightweight, performance-oriented alternative to React that is ideal for PWA development because it is light, fast, and should meet the majority of your needs.
Preact is fully compatible with React, which makes switching from React to Preact as simple as adding a compatibility layer preact-compat to your existing code. This is why it’s so great and highly regarded within the PWA community.
Pros:
Lightweight and quick
It makes use of the same ES6 API as React, which allows for seamless compatibility.
It-just-works Preact CLI provides excellent PWA performance right out of the box.
It includes server-side rendering, routing, and add-ons.
Cons: Many of Preact’s ‘innovations’ require preact-compat to use React components or packages.
PWABuilder
It is an open-source PWA framework founded by Microsoft that provides one of the quickest ways to develop components for a web app that is responsive across devices and platforms. PWABuilder has a large developer community and also supports Android and iOS app development.
Pros
It transforms websites into PWAs with little or no development effort.
PWABuilder provides the simplest way to begin the development process; simply enter the URL in the input line, and it will analyse the components required to build PWAs.
The generated PWA package can be downloaded, or the web app can be enhanced with additional features.
Cons
When the PWA is used, the disadvantage of flexibility causes problems.
Customizing the web app is difficult!
The automated process also makes management more difficult.
PWAs have undeniable value in this day and age, so make sure you select the best Progressive Web App development framework for your business in terms of size, expected scalability, presence of interactive elements, and complexity.
Ionic
Built on the Angular and Apache Cordova Progressive Web App frameworks, Ionic is an open-source SDK. Over five million hybrid apps have been produced using it since its creation in 2013.
Ionic’s massive library of components for both iOS and Android makes it an excellent choice for PWA development. This can be used to create web pages that will run inside the device browser using WebView.
Pros
Ionic is available for free because it is open-source software. It’s a great option for small businesses because of its affordable app development costs.
Anyone who is familiar with Angular and web technologies can use Ionic.
Thanks to debugging tools and built-in browser tools, maintenance is easy.
Ionic has a large plugin library for accessing APIs that do not require any coding.
Cons
Frequent updates necessitate reworking existing PWAs to reflect those changes. This can become tedious over time.
Svelte
Svelte is a new component-based framework as well. Despite being written in a fundamentally different manner, it positions itself in the market as a “reactive framework.” It is released under the MIT licence. Its most recent version was released in 2019, and The New York Times and GoDaddy quickly adopted it.
Pros
Svelte offers faster page loading, a smaller bundle size, and syntactic analysis and execution with less code.
The framework is versatile while remaining simple, as it supports plain CSS as well as various CSS Progressive Web App frameworks.
The PWA package, which covers essential server workers and boilerplates for meta-data social sharing, is included in the Svelte starter template.
Cons
Community support for the framework is essentially nonexistent due to its youth.
Implementation can be difficult because the documentation has not yet been properly developed.
It does not support TypeScript.
Polymer
Polymer is a Google-created open-source web app framework.
It is an independent framework that includes a variety of templates, PWA tools, and web components that use HTML, JS, and JSS.
Furthermore, Chrome and Opera are among the browsers with which Polymer’s tools and components are compatible. Due to this characteristic, the polymer is very adaptable and accessible.
Pros
The APIs are relatively simple to grasp.
It includes excellent documentation, which makes the implementation process easier.
The entire web app stack, including responsive layouts, data tiers, and routing, is supported by Polymer.
Cons
Polymer does not have an office IDE.
The framework is not SEO-friendly, which defeats the purpose of developing a web application.
In contrast to PWAs, it has a long page reloading time.
Because of the embedded development tools in the Progressive Web App development framework, debugging tools are sometimes required.
