I imported my AnalogDisplay component (original in React) into preact JSFiddle code, and they worked well. I can either use this.state or just state in render(). Here’s the JSFiddle code: http://jsfiddle.net/gz7L59mn/1/ and the source code:
This project will guide you through building an autocomplete function similar to the one that you might see in Slack (a popular messaging app), as shown in figure 1, when you type something in the search box. For simplicity, our widget will work with room names (the rooms in a chat application).
The autocomplete widget will have (figure 2):
An input field
A list of options filtered according to the entered characters
An Add button (figure 3)
The filtering of the matches will be done using the entered characters as the first characters of the option. In other words, there is a simple comparison that allows us to autocomplete the name of the room (figure X). For example, if you type “mac” and you have “Mac OS X” and “Apple Mac,” then only “Mac OS X” will be shown as a match, not both options.
In this book, I’ll introduce you to React Native for native mobile iOS and Android development… and do it quickly. We’ll cover topics such as
Why React Native is Awesome
Setting up React Native Development for iOS
Hello World and the React Native CLI
Styles and Flexbox
Main React Native UI components
Importing Modules into an Xcode Project
Project: Weather App
This book is about getting started with React quickly and not about React Native, which is technically a separate library (or some might even call it a framework). But I figured after eight chapters of working with React for web development, it would be fun to apply our knowledge to mobile development by leveraging this awesome library. You’ll be amazed how many React Native skills you already know from React.

This is a kitchen sink of subjectively the most interesting core features. The key takeaways of this essay are:
Event loop: Brush-up on the core concept which enables non-blocking I/O
Global and process: How to access more info
Event emitters: Crash course in the event-based pattern
Streams and buffers: Effective way to work with data
Clusters: Fork processes like a pro
Handling async errors: AsyncWrap, Domain and uncaughtException
C++ addons: Contributing to the core and writing your own C++ addons
We can start with event loop which is at the core of Node.
Node.js Non-Blocking I/O
It allows processing of other tasks while IO calls are in the process. Think Nginx vs. Apache. It allows Node to be very fast and efficient because blocking I/O is expensive!
Take look at this basic example of a delayed println function in Java:
The project for this article will be minimal. The idea is to have a dynamically generated menu which will consist of <a> tags.
We’ll use custom React components Menu and Link. They way we create them is similar to the way we create the HelloWorld component in the previous example. The project will show you how to render nested elements programmatically. In the previous examples, we just coded the children manually. We’ll use the map() function for it.
Also, you can download the entire first chapter for FREE at Manning. The book is scheduled for release in the first quarter of 2016, but early access (e-copy) is available right now. Use code “mardandz” to get 39% off at Manning.
The videos and the source code are open source, meaning they are publicly available. Therefore, you don’t have to buy a book—you can just watch the 14 videos on YouTube (playlist) and go through the code on GitHub (repository).
Also, React is very fast due to its virtual DOM and smart diffing algorithm. And React’s component approach to architecture allows for great development scalability. Just ask Facebook, Twitter, Slack and other companies with large web apps.
Hey, you can even use live reloading when developing apps with React Native. Pure joy! The feature native mobile developers can only dream of! “React is fun, but show me the money”— you can yell. Fair enough.
Have you ever wanted to learn basics of Node.js and the most popular Node.js web framework Express.js? If you are experienced web developer or software engineer who wants to learn Node.js and build some servers along the way, then this self-study workshop is for you.
What is ExpressWorks? It’s an automated tool which allows to learn Express.js from the author of one of the best books on Express.js—Pro Express.js— with this workshop that will teach you basics of Express.js and building Node.js web apps (a.k.a. servers).
You will walk through adventures via command-line interface. Each adventure has a problem, hints, and the solutions.
