Every time I attend a tech conference I usually meet interesting people and found new awesome technologies. It’s great. This year I attended 4 conference in a row (36 talks in 10 days) and I started a new job a few days earlier. During May 2016 I discover dozens of new technologies and I’d like to do my part and “give back to the community” talking about them in a series of posts.

Here is what I discovered attending JSDay 2016 in Verona.

Progressive Web Apps

Progressive Web Apps “take advantage of new technologies to bring the best of mobile sites and native applications to users. They’re reliable, fast, and engaging.” Google says. They are web apps with a great offline experience. Here is a great list of examples.

Service Workers and Web Workers are modern way to run background services in browser using Javascript. Web Workers has better support, Service Workers has better features.

Physical Web is about the ability of the browser to interact with beacons and other external devices without require a native app. Web Bluetooth API gives browsers again more flexibility (the speaker drove a robot using Javascript in browser)

UpUp helps you to make your progressive app to be “Offline First“. The idea is to makes sure your users can always access your site’s content, even when they’re on a plane, in an elevator, or 20,000 leagues under the sea

Reactive Programming

Reactive Programming Paradigm is trendy by now. Cycle.js and ReactiveX takes Observer and Iterators on functional programming. Speakers talks a lot about them.

Traditional frameworks are going reactive thanks to extensions like Ngrx

Model View Intent is going (probably) to replace previous MVC, MVP, MVVM, …

While JSX gains traction thanks to React.js, other solutions, like Hyperscript, are springing up.

Javascript for cross platform apps

Electron, NW.js and many other platforms make possibile to use javascript to build cross platform apps like SlackAtom and Visual Studio Code.

Async Javascript

Asyncronous programming is hard. Javascript never make easier to do it but now things are getting better and better thanks to many new libraries. Fluorine can simply be though of as an abstraction or a DSL and is a structure of code in which you can manage complex asynchronous code with ease. Co do almost the same thing on Node.js.

Task.js takes concept of Generators and Promises to another level defining the concept of Task.

ES7 will close the circle using async and await with the pleasure of native implementation.

chrome-canary-512Debugging in Chrome Canary

The Bleeding edge version of Chrome, Canary, offers you several beautiful beta features like an integrated layout editor able to edit SASS and works with Rails, a powerful animation inspection and enable you to emulate network connectivity and speed.

Most of these feature are available inside Chrome Workspaces.

Also Node.js stuff could be debugged using Chrome engine thank to Iron-node. If you prefer Firefox engine, Webkit, look at Node-inspector.

Misc

I also discover Modernizr and his stunning new website, Can I Use tells you how much is a technologies available on browser, ZeroClipboard and Clipboard.js makes copy and paste easier, Hapi.js is an interesting framework and Highland a powerful stream library for Node.js. I also discovered that I can use WebGL for data processing in browser.

In the end a lot of new discoveries at JSDay 2016 😉
