Progressive Web Apps (PWas) are a web application that has the panache of a native mobile app but the reach of a website. The built environment PWas are an extension of the modern web stack (HTML, CSS, JS) that allows the user to have fast, engaging and reliable experiences on a web browser and preserve the maximum capabilities of native applications such as offline storage, home screen install, push notifications.

However unlike websites, Progressive Web Applications can operate with unreliable internet connectivity through the use of advanced technologies such as service workers and local caching. A user could then access pages or part of content without Internet connection.

PWAs are very responsive; they can be used on phones, tablets, laptops and desktops. Since they run in a browser, they are easier for users to find than using an app store to download to their phone or tablet.

• Installable experiences
• Offline access

Key Characteristics

How Do Progressive Web Applications Work?

PWas operate through the use of a combination of modern web technologies and sophisticated browser behaviors to offer a mobile application‘s user experience. It operate apart from websites because they can be used offline, send push notifications, load quickly, and be added to a home screen without the use of app stores.

1. Service Workers

Service workers run in the background and manage:

• Offline functionality
• Content caching
• Push notifications
• Background synchronization

They enable applications to access – or ‘load’ – data when the connection to the internet is unreliable or non-existent.

2. Web App Manifest

A manifest file contains information such as:

• Application name
• Icons
• Theme colors
• Display mode
• Launch behavior

This makes one able to install freely from the browser.

3. HTTPS Security

PWAs rely on HTTPS, as it provides a security layer that protects users data and also provides support for advanced browser features.
