Progressive Web Apps in 2019

PROGRESSIVE WEB APPS (PWA)

Progressive Web Apps (PWAs) are web applications that are regular web pages or websites, but can appear to the user like traditional applications or native mobile applications. The application type attempts to combine features offered by most modern browsers with the benefits of a mobile experience.

Progressive Web Apps are user experiences that have the reach of the web, and are:

  • Reliable – Load instantly and never show the downasaur, even in uncertain network conditions.
  • Fast – Respond quickly to user interactions with silky smooth animations and no janky scrolling.
  • Engaging – Feel like a natural app on the device, with an immersive user experience.

Key benefits of PWA

  • Push notifications that allow the user to get a quick summary or snapshot of updates or messages
  • Offline functionality that allows the app to continue running in the background on the user’s behavior and activities without the user having to interact with the app directly
  • Responsive layout and easier navigation than the full desktop website on a mobile device
  • All types of hardware access, including geolocation, camera and microphone and screen orientation access
  • Lower data usage, especially important for users in areas with slow or limited internet access
  • Accessibility to all internet users, since the requirement to download the app or pay for the app is completely eliminated.

Why build a Progressive Web App?

Building a high-quality Progressive Web App has incredible benefits, making it easy to delight your users, grow engagement and increase conversions.

  • Worthy of being on the home screen
    When the Progressive Web App criteria are met, Chrome prompts users to add the Progressive Web App to their home screen.
  • Work reliably, no matter the network conditions
    Service workers enabled Konga to send 63% less data for initial page loads, and 84% less data to complete the first transaction!
  • Increased engagement
    Web push notifications helped eXtra Electronics increase engagement by 4X. And those users spend twice as much time on the site.
  • Improved conversions
    The ability to deliver an amazing user experience helped AliExpress improve conversions for new users across all browsers by 104% and on iOS by 82%.

Conclusion

Progressive Web App is the future of web development without any doubt and it is great alternative to other known cross-browser technologies. In the future, e-commerce sites, restaurants, and media sources will transition from native app to Progressive Web App.

It is the right moment for building a PWA app, however, you must keep in mind browser limitations compared to native applications, and different user experience between Apple and Android devices.

React Native allows you to build mobile native apps with Javascript

Fcebook announced that its React Native library is now available on Github. The library allows you to build native iOS and Android applications with JavaScript and Facebook’s React library.

A framework for building native apps with React.

React Native runs JavaScript engine in a separate background thread, which communicates with the native main thread using a batched async messaging protocol. There’s a plugin for React that uses this protocol for communication.

  • With React Native your application logic is written and runs in JavaScript, whereas your application UI is fully native; therefore you have none of the compromises typically associated with HTML5 UI.
  • React introduces a novel, radical and highly functional approach to constructing user interfaces. In brief, the application UI is simply expressed as a function of the current application state.
