Angular 7 Tutorial – Prerequisites

Since Angular 7 is an enhanced version of angular 6 so before learning angular 7 one should have prior knowledge of the previous version of angular.

Definitely not of angularJS that is angular1 as angular 2 is completely rewritten by the team and is completely different from angular 1 after angular 2 all the versions just differ in some features but the base will remain same so one should have prior knowledge of angular 2 to remain familiar with the base and of course typescript, HTML, CSS too.

Various Prerequisites to learn angular 7:

• CSS

What’s New in Angular 7?

In this section of the Angular 7 tutorial, we will discuss the various interesting and unique features of Angular 7:

1. CLI Prompts

It helps users to make a decision. It asks users about “want to add routing? Y/N” and about the type of styles user want to use.

2. Application Performance

Earlier reflect-metadata is used in production but it is required at the time of development. Therefore, ployfill.ts is removed by default in angular 7.

3. Virtual Scrolling

Google accelerates the speed of Angular 7 for a huge scrollable list.

4. Drag and Drop

It comes with the feature of automatic rendering.

5.Bundle Budget

IF the bundle size is more than 2MB, a warning message provided and for above 5MB, an error will be given.

You will get to know more in detail about these features in another tutorial that focuses mainly on “Unique Features of Angular 7”

Angular 7 Architecture

Various units that combine together to build an angular application. Angular 7 tutorial is complete without its architecture and components:

1. Modules

It is a place to group various units related to our application such as directives, components, services, etc.

2. Components

It is a typescript class in which you can create your properties, methods as per requirement and will bound with the HTML page to display the content to end user.

3. Templates

It is the user interface part of an angular application. A template is the HTML page which consists of the content that is being displayed at the user end.

4. Metadata

It is data about data. Decorators are metadata in angular.

5. Data Binding

It is the synchronization between data and DOM. There are two kinds of Data Binding in Angular 7:

• Event Binding
• Property Binding

6. Directive

Directives use for expanding the functionality of the HTML element. Directives in Angular are Structural Directive, Attribute Directive, and Component Directive.

7. Services

Services use to reuse the code. This service creates for that code which is common for more than one component.

8. Dependency Injection

It is an angular design pattern for enhancing efficiency and modularity.

You will get to know more in detail about these features in another tutorial that focuses mainly on “Architecture of Angular 7”

Benefits of Angular 7 For Web Development

Multiple benefits come with angular 7 that invokes user to use it as a framework for their web developments.

Some of the benefits of Angular 7 for web development are as follows:

1. Google Supported Community

Angular comes with Google’s Long-Term Support (LTS). The Google team is very optimistic about Angular’s stability also many Google apps use an angular framework.

2. Plain Old JavaScript Object (POJO)

It does not require any getter and setter function. Every object it uses is a plain old javascript object. It provides javascript functionalities to enable manipulation of an object such as adding properties or removing properties from the object.

3. Declarative User Interface

Angular uses HTML to define the view part of an application which is a convoluted language. Html is a declarative language too. You don’t need to worry about the flow of program when it loads just define what you want as per application requirement and angular will take care of rest things.

4. TypeScript

It is written in typescript, which is a superset of javascript. It promotes high security. If you have created proper map files during build time, then you can easily debug typescript code in an editor or on a browser.

5. Modular Structure

Angular organizes code into modules whether it is components, directives, pipes or services. It makes organizing of functionality easy and simple by separating the code. It also offers lazy loading, means loading of application feature in the background as per the demand of a user.

6. Consistency in Code

It improves the readability of code. For any new developer, it is an easy task to go through the project because of code consistency. It adds to their productivity too.
