Progressive Web Applications (PWA)

What is a Progressive Web App (PWA)?

At the most basic level, Progressive Web Apps (PWAs) are web apps on steroids that combine the features of a traditional web app with the performance and experience of native apps. Specifically, they are a set of guidelines, technologies, design concepts, and web APIs that work in tandem to provide an app-like experience on the web.

Progressive Web App Features

Two key capabilities of PWA are service worker and a manifest. The manifest provides a centralized place for application meta data such as application name, target URL, an app image or icon, configuration data and default display data. This lets a PWA app be loaded on a mobile device or browser and launched by clicking on an icon, like a native application.

The second key capability is the service worker. Service worker is a JavaScript file that acts as an intermediary between the network and device and the application. It handles key functions that mimic a native mobile application.




Manifest handles:

  • Meta data for browser to find and launch
  • Data to control launch process


Service worker handles:

  • Managing push notifications
  • Caching
  • Background data synchronization
  • Centralizing updates
  • Managing network requests

Business Impacts of PWA

The combination of web-based access and searchability with a native user experience can significantly increase application adoption and user engagement. Some of examples of improved engagement and business results include:



Twitter Lite saw a 75% increase in tweets with their PWA

The average time spent by users on Pintrest has increased by 40% with the PWA

Google found that PWA install banners convert 5-6x more often than native install banners

Forbes saw a 43% increase in sessions and a 100% increase in engagement


Oceaneering saw success with PWA's using Temenos Quantum very early and have 4 Progressive Web Apps in production with more under development


ConEdison, a utility company, has already deployed their first Progressive Web App developed using Temenos Quantum



Quantum’s Progressive Web Application Support






Temenos’ Quantum multiexperience development platform has full support for PWA. Within a single project and code base you can build both responsive PWA and native mobile applications from the same project with reusable components across both, all in a unified design canvas.




After creating your application, simply check the PWA application box during the build process and Quantum takes care of creating the Service Worker, Manifest and other artifacts needed for the PWA application.

When running Quantum PWA applications through Google’s Lighthouse tool, we consistently have achieved a 100% PWA rating.
