Push real-time data to Progressive Web Apps (PWA)

Progressive Web Apps (PWAs) are web applications that use the features of modern browsers to offer a native-app-like experience on every platform. They rest on three pillars: responsiveness, reliability, and installability.

PWAs are responsive because they render well on a variety of devices and window sizes to ensure usability and user satisfaction.

PWAs are reliable because they are usable regardless of network connection.

PWAs are installable because they can be added to the user's home screen, dock, or taskbar. It is possible to search for them on a device and jump between them with the app switcher like native apps.

In more and more scenarios, PWAs are replacing native mobile apps and hybrid apps, to save on development and maintenance costs, while enlarging the compatibility with the broad base of client-side platforms.

There are many uses cases where applications need to receive real-time data, pushed by a server over a streaming channel: online trading platform in the financial brokerage space, monitoring dashboards, second-screen applications, group chats, betting solutions, and many more.

Is it easy to push live data to a PWA? The short answer is yes if you use a modern streaming engine like Lightstreamer.

The official Docker image and the Amazon EC2 AMI are available too.

Lightstreamer 7.2 and the most recent client and adapter SDKs bring many improvements and fixes, mainly covering performance and features. This, in many aspects, completes the renovation work started with Lightstreamer 7.0. Below are some highlights but you can check out the full list in the changelog.

Introducing support for Swift Package Manager and Apple Silicon

The latest version of our client SDKs for iOS, macOS, tvOS, and watchOS, version 4.3.0, is now distributed via Swift Package Manager and includes support for Apple Silicon Macs.

At the same time, with this version, we are dismissing CocoaPods as a package manager. The last version available on CocoaPods is and always will be version 4.2.1.

Read on for a quick How-To on switching from CocoaPods to SPM.
