JavaScript for Line of Business Applications

In software engineering, a design pattern is a general reusable solution to a commonly occurring problem within a given context in software design. A design pattern is not a finished design that can be transformed directly into source or machine code. It is a description or template for how to solve a problem that can be used in many different situations. Patterns are formalized best practices that the programmer can use to solve common problems when designing an application or system. Object-oriented design patterns typically show relationships and interactions between classes or objects, without specifying the final application classes or objects that are involved.

The 23 Gang of Four (GoF) patterns are generally considered the foundation for all other patterns. They are categorized in three groups: Creational, Structural, and Behavioral. This small web application explains these patterns and gives examples on how you can use these patterns in TypeScript.

For testing and sharing your React Native apps and snippets,
from the comfort of your browser.

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.

Integrate React.js with Ruby on Rails to build web apps

Summarizing, the application will behave as follows:

• When the user creates a new record through the horizontal form, it will be appended to the records table
• The user will be able to inline-edit any existing record
• Clicking on any Delete button will remove the associated record from the table
• Adding, editing or removing an existing record will update the amount boxes at the top of the page

A intro to the new web component spec by building a simple tab component.

One of the main issues in our components today are style conflicts. This is when our CSS or the imported component breaks CSS somewhere else. Another is lack of native templating of HTML. Storing HTML templates on a page have only been possible by using script tags or other hacks. The current component structures lack of semantic meaning. We end up with a big pile of div's that have little meaning. Angular has tried to help this with its custom element directives.

The new HTML5 Web Component Specification is a collection of specifications that when combined create a powerful web standard for creating reusable components.

In this tutorial we are going to build a character voting app (inspired by Facemash) for EVE Online - a massively multiplayer online game. You will learn how to build a REST API with Node.js, save and retrieve data from MongoDB, track online visitors in real-time using Socket.IO, build a single-page app experience using React + Flux with server-side rendering and then finally deploy it to the cloud.

Tiny Angular version 1 app written in Typescript with modularized Gulp tasks. Perfect as boilerplate.

React in a way, resembles Angular directives but that’s all there is: these directives. In React, they’re called “Components”. When creating a component, certian methods are run (if available). The main one is render which uses data that React exposes (like state, props, etc. more on that later) and uses it to build a fake DOM using “JSX”.

The beauty of ReactJS is its one-way flow which is easier to follow and understand. There is no $digest nor any way to setup $watch. But let’s look at all the cool things about React first:...

In the past I've given presentations, recorded videos, and written blog posts about fixing common JavaScript and jQuery bugs. This is a good skill to have, but what about working code? Fixing broken code is important, but have you ever gotten into the situation where your code works, but it doesn't feel quite right... maybe even smells?

Ember.js is an awesome framework for building rich and powerful front-ends, favoring convention over configuration to make development a breeze. Yet all this convention can hide some dangerous pitfalls, and developers must tread carefully to avoid falling through the cracks.

Thankfully, Toptal developer Balint Erdi is here to shine a guiding light, pointing out these 8 common mistakes for Ember.js developers to watch out for.
