A Short Introduction to Angular

The JavaScript ecosystem contains libraries and web development frameworks. One of these frameworks is Angular. Angular is a web development platform written in TypeScript that is used for developing a single-page web application (SPA).

How Angular came to be and its applicability in web and app development are briefly described below.

Angular Web Application Framework (WAF)

JavaScript (JS) is normally used for building client-side interactive elements that can be displayed on a website. A JavaScript Framework (JSF) provides a set of tools to be used in building a web application, including its design and codebase organization.

Each JSF has its own philosophy that guides web application development. If there is no underlying philosophy, then the set of tools are collectively designated as a JS Library.

Angular JS

learning angular

Angular WAF started off as Angular JS. Angular JS was developed in 2010 by Google Incorporated as a JS web framework for building SPAs.

An SPA is basically any web-page that automatically loads new data from its web server without reloading or refreshing the entire web-page, and this makes the website evoke the feel of a native app.

This way of loading new data into the webpage is called dynamic page update. Angular JS was written in JavaScript, and could control only a section of the web-page – the section that behaves as an app as will be explained later.

The ability to invoke automatic data update in the webpage whenever the original data in the webpage (described as the modal data) is changed is called data binding.

Angular JS introduced data binding, as well as exploited the use of directives. Directives were introduced in JS, and they allow the developer to invent HTML (HyperText Markup Language) tags.

In fact, it is the use of angle brackets to enclose HTML tags (a directive) that led to this JavaScript framework being called Angular.

Moreover, Angular JS allowed components of an application to be connected together so that the developer has reusable code, and this is called dependency injection.

These are among the features that made Angular JS quite popular, and its developers decided to optimize it by developing a new version called Angular 2 or Angular v2.

This new version ended up being a complete rewrite and re-designation of Angular JS, and it also introduced new features including support for mobile platforms, while old concepts were reconsidered.

Versions of Angular

Angular 2 debuted in 2016, and it allowed SPAs to be developed for native desktop app, web, and mobile platforms. Later, misalignment of the Router component in Angular 2 was corrected, and this contributed to the release of Angular 4 later in 2016.

Angular 4 featured router updation and also introduced the Angular command line (CLI). In November 2017, Angular 5 was released, and in May 2018, Angular 6 was released, and later in October 2018, Angular 7 was released.

Angular 5 and 6 supported ng-add and ng-update commands in their CLIs, as well as CLI prompts for displaying tips on the CLI commands being used.

Angular 8 was released in May 2019, and it was followed by Angular 9 in February 2020. Angular 8 introduced the Ivy renderer, which was later adopted as the default compiler in Angular 9.

In June 2020, Angular 10 was released and was followed by Angular 11 in November 2020.

Any version of Angular JS succeeding Angular 2 is now called Angular Web Application Framework or simply referred to as Angular Web Framework (AWF).

SPA and NgModule

The introduction of the front-end web development technology called HTML5 led to the replacement of Microsoft Silverlight and Adobe Flash as tools for creating rich user interfaces (UI) in websites. Relatedly, HTML5 allowed for the development of SPA.

The building block of Angular WAF is called the NgModule, which is the container that stores the services and components of the application.

The component is the code that controls a section of a web-page (screen) called the view, and the accompanying HTML form that explains to Angular how the component is to be rendered is called the template.

Therefore, the NgModule includes the component and its companion template; and this makes the NgModule versatile and maintainable.

Unlike ReactJS, Angular WAF uses the regular Document Object Model (DOM) when building the SPA. This allows for app loading on the webpage.

When the web app is loaded in a webpage, and any further interaction with this app does not lead to the loading of any other webpage, then this app is called a Single-Page web Application (SPA). Angular provides two-way data-binding for the SPA.

Two-way data binding allows the web page to be manipulated through the web browser. Two-way data binding simply means that any changes in the UI is reflected in the model state, while any change made in the model state is reflected in the UI state (the model and UI states are explained in the MVC framework).

TypeScript

As mentioned, Angular is written in TypeScript (TS), which is a superset of JavaScript. Basically, TypeScript is an object-oriented programming language that trans-compiles to JavaScript.

This means that JavaScript code can be saved as a TS code, but unlike JavaScript, TS is strongly typed and supports both dynamic and static typing, as well as has additional features (that are not present in JavaScript).

TS is suitable for writing huge, complex codebases that are prone to errors. The advantage of TS is that the errors can be detected and debugged during code compilation rather than when the code is running on the browser (run-time) as is the case with the interpreted language, JavaScript.

In lieu, TS needs to be compiled in order to run on the browser, unlike JavaScript which directly runs on the browser. To install TS, one must install the NPM package.

MVC Framework

Angular architecture apportions the application into 3 different application layers – the model, the controller, and the view. The model is the data-related logic, and the view is the UI-related logic.

Therefore, the data and how it is displayed (in the UI) are 2 different layers. The brain of this setup is the controller. Angular 1 was based on controllers, while Angular 2 introduced the component-based approach.

There is bi-directional data flow from the model to the controller, and from the controller to the view, but there is no data flow from the model to the view and vice versa. These aforementioned properties make Angular WAF a full-fledged MVC framework.

Angular testing is done using the Jasmine Framework, with Karma serving as the task-runner during the test.
