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 8 Forms | Angular Reactive and Template Forms

Angular Forms are used to handle the user’s input. We can use Angular form in our application to enable users to log in, update profiles, enter information, and to perform many other data-entry tasks.

If you are new to Angular, then check out myAngular Tutorial. If you do not know how to upgrade to Angular 8 via Angular CLI, then check out my Angular Upgrade tutorial. Managing user input with forms is the cornerstone of many web applications.

The web app uses forms to enable the users to log in, to update a profile, to enter sensitive information, and to perform many data-entry tasks.

Angular simple dynamic template-driven form for beginners

Template driven forms are model driven forms driven by directives in a template. Template driven forms are approached by angular JS users but sometimes template driven forms will be used for complex systems. For instance, if you want to dynamically set to validate a particular form filed you can use template driven forms. In the template driven forms uses two way data binding in terms of it uses ngModel despite formControl and fromGroups.

Form structure

I am going to create a simple form that is able to create new form fields. The number of form-fields depends on the user. It can be changed at run time.

However, each form entry requires a name like formControlName in reactive forms and the state of the form as a whole that is a collection of individual form fields. Each form filed is assigned a unique id property. Therefore, template driven form controls need to be uniquely named. We can generate form fields using a unique control name. In this dynamic form, it has been used the current timestamp as a unique id or you can create a method to get random numbers to assign for this unique id. So it can get through with parent NgForm.

First, import formsModule to main module ex:- app.module.ts then create an interface to describe an object. You have to set some properties you want to this interface.

<form #parentForm="ngForm" (submit)="submitParentForm(parentForm)">
	    <ng-template ngFor let-form [ngForOf]="mainForm.formFields" let-index="index" let-isLast="last">
	        <input
	            type="form.formField1.type"
	            name="formFirld1_{{ form.id }}"
	            [(ngModel)]="form.formField1.value"
	            placeholder="form.formField1.placeholder"
	            required
	        />
	        <div *ngIf="parentForm.submitted && !form.formField1.value">Form field 1 is required</div>
	        <input
	            type="form.formField2.type"
	            name="formFirld2_{{ form.id }}"
	            [(ngModel)]="form.formField2.value"
	            placeholder="form.formField2.placeholder"
	            required
	        />
	         <div *ngIf="parentForm.submitted && !form.formField2.value">Form field 2 is required</div>
	        <button (click)="removeForm(index)">Remove form</button>
	    </ng-template>
	    <button type="submit">Submit</button>
	    <button type="button" (click)="parentForm.reset()">
	        Reset
	    </button>
	</form>
	<button (click)="addForm()" [disabled]="(!parentForm.form.valid)">Add new form</button>
