The Swift language is designed to be as interoperable as possible with Objective-C. This goal is generally fulfilled, but an area still remains where the two languages don’t interoperate as well as one would expect: exception handling. Objective-C provides complete try-catch-finally semantics for exception handling, with full stack unwinding. While Cocoa and CocoaTouch conventions discourage…

While Lightstreamer is already well known as a mature solution for Real-Time Data Distribution in a wide range of contexts and industries, it has been also widely used as an academic research tool behind the scenes. A recent one caught our attention. The research is on interoperability of real-time and non-real-time systems, a well-known topic…
Vue.js is an open-source JavaScript library for building interactive web interfaces which is rapidly growing in popularity (as evidenced by its GitHub’s stars).It’s basically a view layer for any application, which enables reactive data binding and composable view components (without polyfills, even in browsers that don’t support those features natively) through an extremely simple API.Vue differs from the alternatives, such…
Last week, we built our first demo in Angular 2. The application implements our evergreen “Basic Stock-List Demo”, which shows ten stocks whose market-data are dynamically updated by a random simulator and sent in real time to the web client by the Lightstreamer Server. Previously, we had done the same exercise using AngularJS (you can see the outcome…

The new SDK has been developed keeping in mind the same principles and concepts which drove the…
Containerization is one of the most important IT trends over the last two years. Docker heads this technology up, providing an open platform which lets you package up applications with all their dependencies. Applications can be shipped as software containers to enable process isolation, resources optimization, portability, and ease of maintainability and deployment. As passionate about each new exciting…
EDIT 2021:the Lightstreamer Web Client, now supporting ES6 module system, has replaced the Node.js Client in React Native applications, so the trick regarding Babel is no longer necessary.In the past few years, we have seen the diffusion of frameworks like PhoneGap and Titanium, which offer developers the opportunity of building mobile applications using web technologies….
Nowadays, since browsers and mobile devices got powerful, there has been a constant decline of desktop applications, which are getting replaced by mobile and web apps. There are a lot of advantages to writing desktop applications and in some context it’s still preferable. GitHub’s Electron framework (formerly known as Atom Shell) wants to give developers new…
With the release of Apple TV 4th generation, Apple added a new platform for the development and distribution of apps. We are happy to announce that Lightstreamer now supports this new platform as well, with the same APIs provided for iOS and OS X. The new tvOS Client SDK is directly derived from the iOS…
