Why Use Angular.js

Comparatively, while Angular does require you to do the splitting up into MVC components of your app, it puts them back together by itself, with no input from you. Another quirk of Angular is the fact that it uses the HTML to define the app’s user interface. Directives are Angular’s way of bringing additional functionality to HTML. There are many reasons why you would want to choose Angular for your projects, not only the ones mentioned above but also a lot more depending on what your requirements are and how you want to improve your web application. However, my advice for you is: Keep in mind solely the needs and requirements of your app and then decide which technology is the most suitable one, without being influenced by the opinions of critics and Angular lovers.

Quick Look – Angular Routing – Don’t Panic Labs

Since Angular is a single page application (SPA) framework, it has to provide some way to handle routing in the browser. In non-SPA applications, page reloads (also known as switches) involve a full reload of the page. In this sample application, we will have four routes (one for each component we have created). At this point, we will be able to navigate to our Contacts and Events pages, but we won’t be able to navigate to our contacts or events details. We will have to modify the Contact Detail page to handle the click event and allow the user to navigate there. Continue reading


Model-View-Presenter with Angular – Angular In Depth

Complex Applications
A complex application is characterised by at least one of these traits:
Multiple components in the component tree that display the same piece of the application state
Several sources of updates for the application state such as:

— Multiple users interacting at the same time
— Back-end systems that push updated state to the browser in real-time
— Scheduled background tasks
— Proximity sensors or other device sensors
Very frequent updating of the application state
A large amount of components
Components built with many lines of code, reminiscent of the Big Ball of Mud AngularJS controllers of the past
A high level of cyclomatic complexity in components — a high concentration of logical branches or async control flows

At the same time, we want an application that is maintainable, testable, scalable and performant. In our applications, we can categorise the software artifacts into these horizontal layers, or system concerns:
Horizontal layers in a web applicationThe same rule can be applied to our Angular components. While this logic is expected in an application, grouping it all in a single place makes it hard to test, difficult to reason about, complicated to reuse and tightly logic and complex presentational logic is extracted into a presenter to get a simple presentational component. The model — represented by container components — is the application state that is displayed to the user for them to browse and alter. The view, represented by presentational components, is a thin user interface that presents the application state and translates user interactions to component-specific events, often redirecting the control flow to the presenter.

Golang & Angular Series – Part 1: Developing and Securing Golang APIs

In the first article, you will build a secure backend API with Golang that will support a to-do list application. As mentioned, the technologies of choice for this series is Golang for the backend and Angular for the frontend. Over the last few years, Golang has become a very popular language, being the language of choice for projects such as Docker, Kubernetes, and all of Hashicorps suite of programs. Either way, Angular is another project backed by Google, much like Golang. Then, after installing Node.js and NPM, you can issue the following command to install the Angular CLI tool:

In this section, you will learn how to build backend APIs with Golang. Continue reading

Connection-Aware Components in Angular – Netanel Basal

Connection-Aware Components in Angular

The navigator.connection object contains a read-only property named effectiveType, which returns the effective connection type. By combining the Network Information API with Angular, we can write components that render different elements for different connection speeds. For example, if we observe a slow connection, we can render a placeholder or a lower resolution version of our image or video in order to improve our page loading time. The connection$ observable will notify us of the current effectiveType value, both on initial page load and on change. The connection component is grabbing the provided slow and fast templates from its view, and rendering the correct template based on the effectiveType property. Continue reading


Is Angular.js more widely adopted than Vue.js? – Quora

  • Now, we discuss what is Angular JS and Vue JS.
  • Vue JS is a JavaScript front-end framework and designed by Evan.
  • The main purpose of Vue is to organize and simplify web development.

Angular JS and Vue JS have so many options that we have today when it comes to frameworks and JavaScript libraries, choosing the best may be a difficult task. Angular JS is an open-source framework for building web application front-end and based on JavaScript and maintained by Google developers to solve the problems during the development of Single Page Application.

Angular.js App Structure

However, there are some very basic rules that I like to keep in mind, as advised by Google Developer Expert John Papa:

I find the task of locating files in a folder oftentimes tedious, especially when the size of the app starts to grow. This is a solution applicable to your app; just keep all the files in one big folder. You have a small to medium sized single page app with a considerable number of files that you want to structure in order to get the easy access and maintainability you’re aiming for. That file would be , containing our angular modules and other general code, while the rest of it will be ided into other folders based on the type of file. After that we have the app folder, which will contain all the relevant code for your app in which you will find two other directories and two files. Continue reading


A comparison between Angular and React and their core languages

Angular and ReactOne thing that is really great about React in terms of performance is the Virtual DOM, which you’ve probably heard about a couple of times. So who uses which shop
onefootball
Google Express
NBA
Delta

If you know of any large, well-known companies using Angular, please share with a link.TypeScript and JavaScript (ES6+)
As I mentioned, it can be misleading to only compare Angular and React without focusing on the core language each one has to offer. It is important to notice that TypeScript was released in the period of ES5, and during that time, ES5 was not a class-based OOP language. Alright, so if you are still confused what statically typed means, check this out:
Static typed property
Static typed property comparison between JavaScript and TypeScriptStatic typed argument
Static typed argument comparison between JavaScript and TypeScriptI’ve learned that lots of people believe that a statically typed language means reliable code, and is most often used as a winning argument over dynamically typed languages. Takeaway notes
React handles memory-management efficiently (virtual DOM)
React uses JavaScript (ES6), a recognized web-language since 1995
Angular uses TypeScript, released in 2012
Statically typed languages are great, but does note make code more reliable
Dynamically typed languages require less time to write and more flexibility to use your creativity (fewer typos)
Learning a statically-typed language may be a challenge, especially if you’ve only been working with dynamically typed languages
ES6 has implemented lots of great features such as modules, classes, spread operator, arrow functions, template literals that allows you to write less, cleaner and more structured code (syntactic sugar)
TS is simply ES6+ with typos and more

Conclusion
The framework/component-library you choose may influence how much time you spend programming and your budget. Continue reading
