At beginning of the summer we released a new Vue component called vue-table-component. Our aim was to create a very easy to use Vue component to render a table with data. You can toy a little bit with the component on the demo page. Recently Seb and I worked on two cool new features which I want to…
In a new blogpost André Neves, a React Native engineer at Big Human, introduces the new features that are coming with ES2017.
I think it is a fair assessment to say that a large portion of JavaScript developers seem to appreciate the new, the shiny, the bleeding-edge tools. Whether it is to completely embrace a new technology, or simply to test out a tool's functionality, we like to know what is out there to at least 'dip our toes in the water'.If you're like me, keen on knowing about all of the new technology this incredible community has to offer, here is a breakdown of what ES2017 has in store.

In an amazing article on SitePoint, Christopher Pitt demonstrates how to create an async PHP server that can requests a fingerprint scan on the client side. He uses React Native, WebSocket, an async PHP server, PHP preprocessing, ... Really amazing stuff.
I’m going to describe the process of building custom multi-factor authentication for all transactions. I don’t want to do the usual (and boring on its own) SMS or push notification one-time-password stuff. I want to build a fingerprint scanner right into my phone.In this tutorial, we’re going to look at how to set up a simple iOS app using React Native. We will also set up an asynchronous HTTP server, with a web socket connection to the app.
We will follow this up by adding fingerprint scanning capabilities to the app, and asking for these fingerprint scans from the HTTP server. Then we will build an endpoint through which GET requests can request a fingerprint scan and wait for one to occur.

Here's a little animation made by Wassim Chegham that shows how async/await can clean up your code.
In the JavaScript world promises are a great way to deal with stuff that needs to happen asynchronously. But there's also another new way to go about it: async/await.
In case you missed it, Node now supports async/await out of the box since version 7.6. If you haven’t tried it yet, here are a bunch of reasons with examples why you should adopt it immediately and never look back.For those who have never heard of this topic before, here’s a quick intro
- Async/await is a new way to write asynchronous code. Previous options for asynchronous code are callbacks and promises.
- Async/await is actually built on top of promises. It cannot be used with plain callbacks or node callbacks.
- Async/await is, like promises, non blocking.
- Async/await makes asynchronous code look and behave a little more like synchronous code. This is where all its power lies.
Hannes Van De Vreken shows what awesome async things you can do with Guzzle promises.
Now what happens if you need to perform a large number of concurrent requests? If you don’t control the number of requests you might end up with a dangerously large amount of open TCP sockets to a server. You’ll need to use some sort of dispatching to have a limited number of concurrent requests at any given time.https://blog.madewithlove.be/post/concurrent-http-requests/Let’s show you how to do that.
A very nice post by Christopher Pitt about generators and how to use them to run code asynchronous.
