Let's start this tutorial with the question: "What is TypeScript?" TypeScript is a typed superset of JavaScript that compiles to plain JavaScript. As an analogy, if JavaScript were CSS, then TypeScript would be SCSS. All the valid JavaScript code that you write is also valid TypeScript code. However, with TypeScript, you get to use static typing and the latest features that get compiled to plain J

A few years ago, when I was still an employee in a mobile consultancy, I worked on an app for a big investment bank. Big companies, especially banks, usually have processes in place to ensure that their software is secure, robust, and maintainable. Part of this process involved sending the code of the app I wrote to a third party for review. That didn’t bother me, because I thought my code was imp

Firebase's goal is to help developers build better apps and grow them into successful businesses. By taking care of your app back-end or infrastructure, Firebase lets you focus on solving problems for your users. One of the new exciting features announced at the Google Cloud Next '17 Conference this March for Firebase was Cloud Functions. In this tutorial, you'll learn about this new feature by bu

React is a JavaScript library for building user interfaces that has taken the web development world by storm. React is known for its blazing-fast performance and has spawned an ecosystem of thousands of related modules on NPM. But with all this complexity, it can be hard to know where to start. So here are eight courses that will teach you everything you need to know. 1. Modern Web Apps With React

Installation If you already develop applications with Java, you probably don't need to download anything at all: JavaFX has been included with the standard JDK (Java Development Kit) bundle since JDK version 7u6 (August 2012).  If you haven't updated your Java installation in a while, head to the Java download website for the latest version. Basic Framework Classes Creating a JavaFX program begins

In this tutorial, you'll learn how to lay out React Native apps and how to implement layouts commonly used in apps. This includes the Stack Layout, Grid Layout, and Absolute Layout. I'll be assuming that you already know the basics of styling a React Native app and how to use CSS in general, so I won't dwell too much on StyleSheet.create and how to add styling to different elements. Project Setup

In a previous series, I provided an in-depth guide to working with the WordPress Settings API. For those who are new to WordPress or who have been using other tools such as The Customizer to handle various options, it may be something that you have not had to use in your theme or plugin development. As stated in the Codex: The Settings API, added in WordPress 2.7, allows admin pages containing set

First of all, let me show you the final look of the chat application that we will completed by the end of this article. We will implement the application with Flask, Gunicorn for standalone WSGI application, and Flask-SocketIO for real-time communication. 1. Scenario Let's look at an example scenario that we can use throughout this article as we build the application: Alberto wants to use our appl

There are many ways to generate PDFs in Ruby and Rails. Chances are that you are already familiar with HTML and CSS, so we are going to use PDFKit to generate PDF files using HTML from standard Rails view and style code. Introduction to PDFKit Internally, PDFKit uses wkhtmltopdf (WebKit HTML to PDF), an engine that will take HTML and CSS, render it using WebKit, and output it as a PDF with high qu

If you have lived on the “fat models, skinny controllers” diet, you have definitely been going in the right direction. Keeping controllers skinny, though, is not as easy as it sounds. In this article you’ll learn a couple of beginner-friendly approaches for losing some controller fat. Topics Fat Controllers Non-RESTful Controllers Rat’s Nest Resources FAT Controllers Well, “fat models, skinny cont

The let helper method in RSpec is very frequently used for creating instance variables that are available between multiple tests. As an eager student of TDD practices, you have probably written your fair share of these, but following this practice can easily lead to having lots of mystery guests showing up—see below—which is definitely not something we need to have crashing our party! This particu

What You'll Be CreatingIntroduction Back in the early days of Android, when good user interface frameworks were non-existent and most Android devices were underpowered, creating hybrid apps—apps developed using web technologies, such as HTML5, CSS, and JavaScript—was a really bad idea. Compared to native apps, they looked markedly different and performed poorly. Those days, however, are long gone.

In this beginner-friendly series, we’re looking at AntiPatterns, which—as the name implies—represent pretty much the opposite of design patterns. They are discoveries of solutions to problems that you should definitely avoid. In this article we’ll focus on the main View AntiPattern—PHPitis—and work through a couple of techniques to keep your views lean and mean. Having tons of Ruby code in your vi

One of the most significant changes to Android design was introduced during the 2014 Google I/O conference, material design. Even though Google had introduced a set of guidelines for their new design philosophy, developers were responsible for implementing the new patterns from scratch. This led to many third party libraries that achieved the goals of material design with similar, but different, i

As a developer, your design skills may not be that great. But you want your applications to look great. Right? In this quick tip, I list 20 graphic resources for iOS you can find on GraphicRiver.

Introduction Graphical resources in the digital world are of two basic types, raster and vector. Raster images are essentially a rectangular array of pixel intensities. Vector graphics, on the other hand, are mathematical representations of shapes. While there are situations in which raster images are irreplaceable (photos, for example), in other scenarios, vector graphics make capable substitutes

Working with PHP for the past 10 years or so has taken me through quite a ride. Starting with rookie mistakes like not being able to find a semicolon to trying to build my own framework for building sites (do not do this), I finally arrived at something great when I learned object-oriented PHP. Almost all CMS systems use it, including Joomla, Drupal and WordPress, and of course many frameworks lik

Introduced with the Vision libraries in Play Services 8.1, Face Detection makes it easy for you as a developer to analyze a video or image to locate human faces. Once you have a list of faces detected on an image, you can gather information about each face, such as orientation, likelihood of smiling, whether someone has their eyes open or closed, and specific landmarks on their face. This informat

Introduction In this tutorial, I will explain you step by step how to create a modern, hybrid, mobile application (iOS and Android) of your WordPress website using the latest technologies. We'll be using Ionic Framework, ECMAScript 6, npm, webpack, and Apache Cordova. At the end of this tutorial you will get the following application. It has only three modules, a Home module that displays your lat

Introduction One of the many APIs available in Google Play Services is the Nearby Connections API. Introduced in early 2015, this framework lets you set one device running your application as a host and have multiple other devices connect to it in order to communicate over a Local Area Network (LAN). Use cases for this feature include connecting a phone to an Android TV for controlling an app and

Mobile apps and viewing content on the web are ubiquitous now. For years, iOS developers have been charged with either creating their own web viewing experience inside their app or handing off the URL to Safari. Both of these approaches bring inherent disadvantages that were previously unavoidable. That's all changed with iOS 9 and the introduction of the SFSafariViewController class. With it, you
