How to Implement Node + React Isomorphic JavaScript & Why it Matters

How to Implement Node + React Isomorphic JavaScript & Why it Matters | Angular.js and Google Dart | Scoop.it

With the proliferation of more and more of the web being driven by JavaScript, The speed of the browser DOM is becoming increasingly noticeable.

Lots of sites being driven by popular JavaScript frameworks like Ember, Backbone, or Angular can take a while to render into the DOM. This forces the user to wait for the app to bootstrap itself before they can start viewing & ‘using’ the app.

Common Misconceptions About Inheritance in JavaScript

Common Misconceptions About Inheritance in JavaScript - JavaScript Scene - Medium

Classical and prototypal inheritance are fundamentally and semantically distinct.

There are some defining characteristics between classical inheritance and prototypal inheritance. For any of this article to make sense, you must keep these points in mind:

In class inheritance, instances inherit from a blueprint (the class), andcreate sub-class relationships. In other words, you can’t use the class like you would use an instance. You can’t invoke instance methods on a class definition itself. You must first create an instance and then invoke methods on that instance.

In prototypal inheritance, instances inherit from other instances. Usingdelegate prototypes (setting the prototype of one instance to refer to anexamplar object), it’s literally Objects Linking to Other Objects, orOLOO, as Kyle Simpson calls it. Using concatenative inheritance, you justcopy properties from an exemplar object to a new instance.

This article will give you an overview of how to build JavaScript applications with the Flux pattern. It's the minimal amount of material to get you familiar with the core Flux concepts. You should follow along with the accompanying starter kit. You'll need a basic understanding of React and preferably some experience building components.

Reactive ReactJS: improving data flow using reactive streams

Reactive ReactJS: improving data flow using reactive streams | Angular.js and Google Dart | Scoop.it
Many people that use ReactJS as their renderer are using some kind of the
Flux architecture to store data, react to actions and notify components
about changes. After a University project involving Scala and RxJava, I wanted
to use these ideas together with ReactJS views. Besides that I found two things
missing in the Flux architecture:

composing different kinds of data easily
interaction with the server

Of course there are ways to solve this, but perhaps reactive streams can help
ease these shortcomings.

RxJS - Javascript library for functional reactive programming.

RxJS - Javascript library for functional reactive programming. | Angular.js and Google Dart | Scoop.it

One question you may ask yourself, is why RxJS? What about Promises? Promises are good for solving asynchronous operations such as querying a service with an XMLHttpRequest, where the expected behavior is one value and then completion. The Reactive Extensions for JavaScript unifies both the world of Promises, callbacks as well as evented data such as DOM Input, Web Workers, Web Sockets. Once we have unified these concepts, this enables rich composition.

To give you an idea about rich composition, we can create an autocompletion service which takes the user input from a text input and then query a service, making sure not to flood the service with calls for every key stroke, but instead allow to go at a more natural pace.

Flux in Depth. Overview and Components.

Flux in Depth. Overview and Components. | Angular.js and Google Dart | Scoop.it
This is the first blog post of the series “Flux in Depth”. Is this “yet the another flux tutorial”? What I have seen so far, while researching flux, were mostly “how-to” tutorials (usually with todo applications), which describe the main components of given flux application and the data flow between them. This is definitely useful for getting a high-level overview of how everything works but in reality there are plenty of other things, which should be taken under consideration. In this series of posts I will try to wire theory with practice and state my own solutions of problem I face on daily basis. Since these solutions might not be perfect, I’d really appreciate giving your opinion in the comments section below.

Loupe - Understand JavaScript's Call Stack and Event Loop

Loupe is a little visualisation to help you understand how JavaScript's call stack/event loop/callback queue interact with each other.

Loupe runs entirely in your browser.It takes your code.Runs it through esprima, a JS parser.Instruments it a bunch so that loupe knows where function calls, timeouts, dom events, etc happen.Adds a whole bunch of while loops everywhere to slow down the code as it runs.This modified code is then turned back into JavaScript and sent to a webworker (in your browser) which runs it.As it runs, the instrumentation sends messages to the visualisation about what is going on so it can animate things at the right time.It also has some extra magic to make dom events, and timers work properly.

Native Mobile Apps in JavaScript with Tabris.js

Native Mobile Apps in JavaScript with Tabris.js | Angular.js and Google Dart | Scoop.it

Today I want to highlight the rather new and unknown JavaScript framework Tabris.js.

In contrast to many other hybrid frameworks, Tabris.js is no HTML5 + WebView framework, but still offers the possibility to use Javascript libraries, npm modules and Cordova plugins! I will show you the strengths, we will develop a simple app to get a feeling for the code structure and finally inspect the similarities and differences to other well known frameworks.

Sounds good? Let’s take a closer look!

How to use React & Om to make a Single Page Application (SPA)

How to use React & Om to make a Single Page Application (SPA) | Angular.js and Google Dart | Scoop.it

Clojure is a Lisp-based language that compiles and executes on the JVM. WithClojureScript, Clojure can be cross-compiled to JavaScript. Developing a SPA in a language like ClojureScript allows developers to utilize Clojure’s features like static type safety and immutability when working with large or complex applications. The Om project allows a developer using ClojureScript to interface with React in a client-side application. Let’s get started using React and Om to build a SPA.

Replaying bugs with Flux

Replaying bugs with Flux | Angular.js and Google Dart | Scoop.it

It’s important to note that with React with Flux, the application state lives outside of the UI-components, in the store(s). The stores populate their state according to the actions and the UI merely reflects this state. A UI defined with React can be seen as a pure function: given the same input (state), it will always produce the same output (ui).

Flux was inspired by CQRS and Event Sourcing. For those unfamiliar: think think of it as a simple version control system: each action is a commit, all consecutive commits give you the current state.

To record actions in Flux, we need to either extend the dispatcher with this functionality or create a new component which listens to the dispatcher. I’ve published a proof-of-concept on GitHub called FluxRecorder, which does the latter.

Announcing Arch - a functional style application framework for React

Announcing Arch - a functional style application framework for React | Angular.js and Google Dart | Scoop.it

Arch is a front-end functional style application framework using React as a UI layer. Arch applications are isomorphic out of the box, including form processing. This means you write your application as if it was client-side only and Arch will manage the server-side portion.

This also means you don’t get any control over the code running server-side, which is a design decision. The theory behind it is that any server-side code you need to run should sit in a separate server application which you talk to over an API.

Reusable Chart Components with React And D3

Reusable Chart Components with React And D3 | Angular.js and Google Dart | Scoop.it

The following should be an introduction to combining D3 with React to create reusable chart components. This is not intended to be an introduction into D3 nor React.

D3s approach to data visualization fits well with the React way of building UI components and App structuring. React encourages to figure out how to structure a number of components to enforce a data flow that moves from top down, meaning that lower level components receive data and render it at best and only keep state if needed, but never manipulating any data that might affect the higher up components.

Another strong correlation between the libraries is their respective component lifecycle. D3 has enter, update and exit.
