Aurelia vs Angular: 9 Most Valuable Differences You Should Know

Difference between Aurelia and Angular

Aurelia is an emerging modern User Interface framework for JavaScript. This framework focuses on business logic rather than other features of the framework. It is a simple, concise and easy to use framework for the front end web applications. Its different features are two-way binding, extensible HTML, modern architecture, support for different languages, easily manageable and testable. Angular is also a front-end framework that was based on TypeScript language. It supports cross-platform and modern web browsers. It has different features like dynamic loading, reflection, an asynchronous compilation of the templates.

Aurelia

Aurelia was backed by Durandal Inc. It was licensed under the MIT license. Aurelia provides great rendering speed, very good memory efficiency, unidirectional data flow which is safer, higher standards of compliance, greater integration compatibility with different other platforms or frameworks. Aurelia is an open-source framework and is licensed under MIT.

Angular

Angular was developed and is maintained by an Angular team at Google with a group of community and individual contributors. It was licensed under the MIT license. It was initially released in the year 2016. It was written in Typescript. Its code was hosted on the Github repository. The latest version of the angular is Angular 6 which is released on May 2018. The code is based on modularity and has different components as it is a component-based model. Angular provides greater speed and performance and supports the development across all the platforms and supports different tools with integration and mainly it was backed by Google, it has a more user base and the larger community that is more credible and reliable.

Install Angular - Angular Environment Setup Process

Angular is a TypeScript based framework that works in synchronization with HTML, CSS, and JavaScript. To work with angular, domain knowledge of these 3 is required.

1. Installing Node.js and npm
2. Installing Angular CLI
3. Creating workspace
4. Deploying your First App

In this article, you will get to know about the Angular Environment setup process. After reading this article, you will be able to install, setup, create, and launch your own application in Angular. So let’s start!!!

Install Angular in Easy Steps

For Installing Angular on your Machine, there are 2 prerequisites:

• Node.js
• npm Package Manager

Node.js

First you need to have Node.js installed as Angular require current, active LTS or maintenance LTS version of Node.js

Download and Install Node.js version suitable for your machine’s operating system.

Npm Package Manager

Angular, Angular CLI and Angular applications are dependent on npm packages. By installing Node.js, you have automatically installed the npm Package manager which will be the base for installing angular in your system. To check the presence of npm client and Angular version check of npm client, run this command:

1. npm -v

Installing Angular CLI

• Open Terminal/Command Prompt
• To install Angular CLI, run the below command:

1. npm install -g @angular/cli

· After executing the command, Angular CLI will get installed within some time. You can check it using the following command

1. ng --version

Workspace Creation

Now as your Angular CLI is installed, you need to create a workspace to work upon your application. Methods for it are:

• Using CLI
• Using Visual Studio Code

1. Using CLI

To create a workspace:

• Navigate to the desired directory where you want to create your workspace using cd command in the Terminal/Command prompt
• Then in the directory write this command on your terminal and provide the name of the app which you want to create. In my case I have mentioned DataFlair:

1. Ng new YourAppName

• After running this command, it will prompt you to select from various options about the CSS and other functionalities.

• To leave everything to default, simply press the Enter or the Return key.

Angular Sass: How To Use Sass In Angular 9 Tutorial

Angular supports Sass, CSS, and Less to style global application styles as well as component styles. Angular components styles have an effective CSS encapsulation mechanism that assures any component CSS is local to the component and does not globally alter any styles.

Angular Sass Example

Why use Angular Sass? Well!! Sass (Syntactically Awesome Style Sheets) is an extension of CSS that allows you to use things like variables, nested rules, inline imports, and more. It also supports you to keep things organized and enables you to create style sheets faster.

In short,  Sass is a CSS preprocessor, which combines unique features such as variables, nested rules, and mixins (sometimes referred to as syntactic sugar) into regular CSS. The main object of Sass is to make the CSS coding process more comfortable and more efficient.

Sass is compatible with all versions of CSS. When working with the Angular CLI, the default stylesheets have the .css extension. We are using Angular CLI 8. So, if you have not used previously, then please upgrade your  CLI version. We will use the Bootstrap 4 Framework for this demo and see how we can configure the Sass in our Angular 9 application.

Angular 9 CRUD by Example

Throughout this Angular 9 CRUD tutorial, we’ll be learning to implement CRUD operations by example using the latest Angular 9 version that has been released recently with Ivy support.

> ✋✋ Join our Facebook group 👈 to discuss anything related to Angular development.

We’ll make use of a CRUD REST API built using json-server which allows you to generate a full working REST API in no time.

What’s CRUD?

CRUD stands for Create, Read. Update and Delete — a set of operations often implemented in web apps to allow users to interact with a database.

In our tutorial, we’ll only focus on building the front-end using Angular 9, the back-end will be mocked using json-server.

We’ll not be learning how to use json-server but you can see the complete instructions from this tutorial after creating the Angular 9 project.

Angular 9 CRUD Tutorial Steps

• Step 1 — Mocking the Backend Using json-server
• Step 2 — Creating an Angular 9 Module
• Step 3 — Importing Angular HttpClientModule and FormsModule
• Step 4 — Creating Angular 9 Component(s)
• Step 5 — Adding Angular 9 Routing
• Step 6 — Creating an Angular 9 Service
• Step 7 — Creating a Model
• Step 8 — Implementing the CRUD Methods
• Step 9 — Calling the CRUD Methods

Basics of Angular: Part-1

What is Angular? What it does? How we implement it in a project? So, here are some basics of angular to let you learn more about angular.

Angular is a Typescript-based open-source front-end web application platform. The Angular Team at Google and a community of individuals and corporations lead it. Angular lets you extend HTML’s syntax to express your apps’ components clearly. The angular resolves challenges while developing a single page and cross-platform applications. So, here the meaning of the single-page applications in angular is that the index.html file serves the app. And, the index.html file links other files to it.

We build angular applications with basic concepts which are NgModules. It provides a compilation context for components. At the beginning of an angular project, the command-line interface provides a built-in component which is the root component. But, NgModule can add a number of additional components. These can be created through a template or loaded from a router. This is what a compilation context about.

What is a Component in Angular?

Components are key features in Angular. It controls a patch of the screen called a view. A couple of components that we create on our own helps to build a whole application. In the end, the root component or the app component holds our entire application. The component has its business logic that it does to support the view inside the class. The class interacts with the view through an API of properties and methods. All the components added by us in the application are not linked to the index.html. But, they link to the app.component.html through the selectors. A component can be a component and not only a typescript class by adding a decorator @Component. Then, for further access, a class can import it. The decorator contains some metadata like selector, template, and style. Here’s an example of how a component decorator looks like:

@Component({
    selector: 'app-root',
    templateUrl: 'app.component.html',
    styleUrls: ['app.component.scss']
})

Role of App Module

Modules are the package of functionalities of our app. It gives Angular the information about which features does my app has and what feature it uses. It is an empty Typescript class, but we transform it by adding a decorator @NgModule. So, we have four properties that we set up on the object pass to @NgModule. The four properties are declarations, imports, providers, and bootstrap. All the built-in new components add up to the declarations array in @NgModule.

@NgModule({
declarations: [
  AppComponent,
],
imports: [
  BrowserModule,
  HttpClientModule,
  AppRoutingModule,
  FormsModule
],
bootstrap: [AppComponent]
})

What is Data Binding?

Data Binding is the communication between the Typescript code of the component and the template. So, we have different kinds of data binding given below:

• When there is a requirement to output data from our Typescript code in the HTML template. String interpolation handles this purpose like {{data}} in HTML file. Property Binding is also used for this purpose like [property] = “data”.
• When we want to trigger any event like clicking a button. Event Binding works while we react to user events like (event) = “expression”.
• When we can react to user events and output something at the same time. Two-way Binding is used like [(ngModel)] = “data”.
