What is Angular 6 Data Binding?

Angular 6 Data Binding : 

Data Binding is available right from AngularJS, Angular 2,4 and is now available in Angular 6 as well. We use curly braces for data binding - {{}}; this process is called interpolation. We have already seen in our previous examples how we declared the value to the variable title and the same is printed in the browser.

The variable in the app.component.html file is referred as {{title}} and the value of title is initialized in the app.component.ts file and in app.component.html, the value is displayed.

What is Angular 6 Modules?

Angular 6 Modules:

Module in Angular refers to a place where you can group the components, directives, pipes, and services, which are related to the application.

In case you are developing a website, the header, footer, left, center and the right section become part of a module.

To define module, we can use the NgModule. When you create a new project using the Angular -cli command, the ngmodule is created in the app.module.ts

What is Angular 6 Components?

Angular 6 Components : 

Major part of the development with Angular 6 is done in the components. Components are basically classes that interact with the .html file of the component, which gets displayed on the browser. We have seen the file structure in one of our previous chapters. The file structure has the app component and it consists of the following files −

• app.component.css
• app.component.html
• app.component.spec.ts
• app.component.ts
• app.module.ts

The above files were created by default when we created new project using the angular-cli command.

If you open up the app.module.ts file, it has some libraries which are imported and also a declarative which is assigned the appcomponent as follows − https://www.tutorialspoint.com/index.htm

What is Angular 6 Project Setup?

Angular 6 Project Setup : 

AngularJS is based on the model view controller, whereas Angular 4 is based on the components structure. Angular 6 works on the same structure as Angular4 but is faster when compared to Angular4.

Angular6 uses TypeScript 2.9 version whereas Angular 4 uses TypeScript version 2.2. This brings a lot of difference in the performance.

To install Angular 6, the Angular team came up with Angular CLI which eases the installation. You need to run through a few commands to install Angular 6.

What is Angular 6 Environment Setup?

Angular 6 Environment Setup : 

Environment Setup required for Angular 6. To install Angular 6, we require the following −

• Nodejs
• Npm
• Angular CLI
• IDE for writing your code

Nodejs has to be greater than 8.11 and npm has to be greater than 5.6.

Nodejs

To check if nodejs is installed on your system, type node -v in the terminal. This will help you see the version of nodejs currently installed on your system.

C:\>node -v
v8.11.3

If it does not print anything, install nodejs on your system. To install nodejs, go the homepage https://nodejs.org/en/download/ of nodejs and install the package based on your OS.

What is Angular 6 Overview?

Angular 6 Overview:

There are five major releases of Angular. The first version that was released is Angular 1, which is also called AngularJS. Angular 1 was followed by Angular 2, which came in with a lot of changes when compared to Angular 1.

The structure of Angular is based on the components/services architecture. AngularJS was based on the model view controller. Angular 6 released in May 2018 proves to be a major breakthrough and is the latest release from the Angular team after Angular 5.

Angular 6 is almost the same as Angular 5. It has a backward compatibility with Angular 5. Projects developed in Angular 5 will work without any issues with Angular 5.

Let us now see the new features and the changes made in Angular 5.

Angular 5 and its Features

Angular 5 was released in Nov 2017. As per its goal of speed and size, It was way faster and of smaller size than that of Angular 4. Following are the features that were introduced in Angular 5.

• HTTPClient API − HTTPClient API was introduced to deprecate the HTTP library. HTTPClient API is much faster, secure and efficient than HTTP library.
• Multiple export aliases − A component can be exported using multiple aliases to ease the migration process.
• Internationalized Pipes for Number, Date, and Currency − New pipes are introduced for better standardization.
• Lambda support − lambda expressions with proper names can be used instead of functions.
• Build Optimizer - Build Optimizer introduced. It optimizes the build size and improves the application speed. Angular CLI uses Build Optimizer automatically.
• Improved Compiler − Compiler from Angular 5 onwards supports incremental compilation leading for faster compilation. Compiler uses TypeScript transforms, a new feature of TypeScript 2.3 available onwards.

What is Angular 6 ?

Angular 6 is a JavaScript framework for building web applications and apps in JavaScript, html, and TypeScript, which is a superset of JavaScript. Angular provides built-in features for animation, http service, and materials which in turn has features such as auto-complete, navigation, toolbar, menus, etc. The code is written in TypeScript, which compiles to JavaScript and displays the same in the browser.
