Today there are over 1.3 billion websites and more than 3.5 million mobile applications on the wide web. But most developers around the world are talking about a new hot trend: Progressive Web Apps. In 2018 they are expected to become a powerful competitor for natives or hybrid apps.
Native mobile applications, the original mobile apps, are developed specifically for Apple’s iOS and Google’s Android. They use languages such as Java for Android and Swift or Objective-C for iOS. Progressive web apps, however, feel like native apps, but in fact are web pages designed for outstanding user experience. Compared to their predecessors, PWA’s do not need to be accessed through an app store. This means that users can find the app on any browser. Thus, they can use them on any device and don’t need to download the app.
Hybrid frameworks for building mobile apps have been evolving massively over the past few years. Today, Google’s Ionic and Facebook’s React Native are leading the way. These frameworks enable developers to build hybrid apps that can pretty much do what native apps are capable of.
What are Progressive web apps?
Progressive Web Apps (PWAs) make use of multiple technologies to develop websites that perfectly mimic a mobile app. They bring together the specifications of typical web pages and mobile apps. This means that they offer the smooth “app-like” experiences. However, being a website at the core, PWAs need to be programmed only once. For this reason, they work the same on all devices, ensuring an improved performance and enhanced usability. This also means that PWA’s have the potential to positively impact mobile web conversion rates while eliminating the need for app stores and reducing development costs.
How do PWA’s work?
PWAs’ structure is simple:
- The content – the information provided by the app, like blog posts;
- The manifest – information about the app, like name, authors or icon;
The design and content of an app or website depend on the industry, business model, developing team, and so much more. But, in general, Progressive Web Apps work based on two main building blocks: the manifest and the service workers. The manifest provides basic information about the app. This information is contained in the JSON structure of the app and can provide the name, authors, the icon and the description of the app. The purpose of this data is to help users cache the app on their screen just like they would do with any other mobile app.
PWA, Native or Hybrid?
While all three types of apps have their qualities to offer, PWA’s have some improvements over both the natives and the hybrids, such as:
As shown above, PWA’s, being websites, can easily be found in any search engine and indexed. This eliminates the need to go through the long process of going into an app store, download and install the app and so on. Also, when developing a progressive web application, developers need only to create one version of the app, that will work the same on any device. Unlike native or hybrid apps that need to be written in different programming languages for different devices and operating systems.
The only downside of PWAs is that they do not work fully with Safari (iOS). The apps offer all the features above, except working offline and push notifications. However, Apple is considering implementing Service Worker to solve this issue.
In conclusion, PWA’s are an improvement to apps as we know them. But if you already have a website or an app, you do not need to give them up. All three types of mobile apps have their advantages and disadvantages.
