Vole.cc - a social network for your browser, built on the power of Bittorrent, Go and Ember.js

Vole.cc - a social network for your browser, built on the power of Bittorrent, Go and Ember.js | JavaScript for Line of Business Applications | Scoop.it

Vole is a web-based social network that you use in your browser, built on the power of Bittorrent, Go and Ember.js

Vole feels and behaves like the web apps you're used to, but it works completely differently. Instead of the web browser sending your data to a central server, it connects to your local machine, saving your data to a folder on your computer.

This folder is shared with other Vole users by giving out a read-only key that allows them to see a stream of your posts, updated live on their computers. By exchanging keys with your friends or people who you'd like to follow, you can form a network that is self-supporting and self-controlled.

A complete guide to Ember - Ember.js Tutorial

A complete guide to Ember - Ember.js Tutorial | JavaScript for Line of Business Applications | Scoop.it

Why Ember.js?

  • Convention over configuration. It reduces the configuration related codes like anything.
  • Much better data change observing mechanism than angular.js like frameworks.
  • A priority based run loop, who decides which task to run first.
  • Built in architecture (with ember cli) has its own advantages. Easier to shuffle developers across teams.
  • ES6 syntaxes. Modern technology.
  • Huge community. Ember even has npm like emberobserver.

Reactivity in Frontend JavaScript Frameworks

Reactivity in Frontend JavaScript Frameworks | JavaScript for Line of Business Applications | Scoop.it
With today’s modern JavaScript frameworks, we are used to the fact that when the application state changes, the DOM is updated automatically. But how do the frameworks detect state changes, and how do they efficiently propagate the changes through the system? Evan answers these questions based on his experience building Vue.js.

Will WebSocket survive HTTP/2?

HTTP/2 is poised to eliminate much of the waste that developers deal with. Multiplexed connections will eliminate the need to bundle JavaScript libraries together. But is HTTP/2 a panacea to all our problems? What about WebSocket? Allan Denis tells us what HTTP/2 is good at and debunks some myths about what it can do.

Recycle — Truly Functional and Reactive way of writing React apps

Recycle — Truly Functional and Reactive way of writing React apps | JavaScript for Line of Business Applications | Scoop.it

One of the most popular FRP JavaScript framework today is — Cycle.js.

Although, Recycle uses React, its actually inspired with Cycle.js. Recycle initial version had nothing to do with React and was made as an “opinionated version of Cycle.js”.

But, as it turns out, defining components composed of a view, actions and functions responsible for modifying state is a model that can be described without the use of the main function, drivers or complex stream manipulations.

Angular 2 and Observables: Data Sharing in a Multi-View Application

Angular 2 and Observables: Data Sharing in a Multi-View Application | JavaScript for Line of Business Applications | Scoop.it
Learn the benefits Observables can provide when you are developing complex web applications.

While a Promise represents a value to be resolved in future, an Observable represents a stream of values throughout. An Observable may be completed, which means it won’t emit any further values. An Observer subscribes to these Observables. These Observers are essentially callbacks to emissions of the Observable. This paradigm supports asynchronous operations naturally. In our application, the Angular 2 components have functions which act as Observers, while the data-sharing service can act as an Observable.

Multifactor Authentication in your React Apps

Multifactor Authentication in your React Apps | JavaScript for Line of Business Applications | Scoop.it

Security can't be overemphasized when it comes to developing software applications. A single authentication factor system (e.g username and password) is no longer safe enough. If credentials are stolen, a user can be impersonated. Implementing a multi-factor authentication system increases security by requiring the user to provide an additional sets of credentials before they are granted access.

Implementing multi-factor authentication can be time-consuming, challenging, and often difficult to get right. However, in this post I'll show you how to quickly implement multi-factor authentication in your React applications in just a few minutes without breaking a sweat!

Getting Started with Node, Express and Postgres Using Sequelize | JavaScript for Line of Business Applications | Scoop.it

We're going to be using PostgreSQL and Sequelize as the ORM of choice to write a minimalistic Todo list application.

By the end of this tutorial, we will have created an API for a todo list application that will enable us to create multiple todos, add list items to those todos, update the list items and delete them. By working through an application in which we implement functionality to add things, update and delete them from a database, this tutorial will serve as an introduction to writing more advanced CRUD applications.

Server-Side Rendering in Angular 2 with Angular Universal

Server-Side Rendering in Angular 2 with Angular Universal | JavaScript for Line of Business Applications | Scoop.it

The conventional server rendering solution has saved us for years with Angular 1 by provisioning web crawlers with our actual content. That seemed to keep us happy but we were missing one thing -- state.

The Universal idea is to build an app that does not just render to server but also runs on the server. Running in the sense that our state, content and styles are intact on the client and the server as well. In Angular 2, this is achieved with the help of Angular Universal which loads our app on the server first, and then drops it to the browser once ready.

Angular 2 best practices: Change detector performance

Angular 2 best practices: Change detector performance | JavaScript for Line of Business Applications | Scoop.it
Follow these Angular 2 best practices to eliminate needless change detection, making your web app faster and cleaner.

In order to guarantee that the DOM always shows the very latest available data, Angular monkey-patches every entry point to running Javascript with a Zone. So any time Javascript finishes executing—meaning an AJAX request completes, a click event handler runs, or a Promise is fulfilled—Angular 2 checks whether any changes have occurred that would affect the DOM.

A clear convention for a CRUD with standard Ember + Ember Data

Ember's official documentation describes a number of low-level APIs, but doesn't talk much about how to put them together. As a result, a simple task such as creating a simple CRUD application is not obvious to a newcomer.

To help solving this problem, I decided to figure out and document a clear convention for simple CRUD apps, using Ember and Ember Data with no third-party add-ons.
