How to Use External and Custom JavaScript in Angular 8|7

In this tutorial, we’ll learn how to use external and custom JavaScript libraries/code in Angular 8 projects which are based on TypeScript.

Prerequisites

You will need to have the following prerequisites:

• Node and NPM installed on your machine,
• Angular CLI 8 (npm install -g @angular/cli),
• An Angular project.

You can create an Angular project by running the following command in your terminal:

$ ng new angular-javascript-demo

In the recent versions of Angular, you’ll be prompted by the CLI for a couple of questions such as if Would you like to add Angular routing? (y/N) and Which stylesheet format would you like to use?. You can answer these questions as you see fit because this won’t affect how to use JavaScript libraries in your Angular project.

Let’s now see how we can use external JavaScript in Angular 8. We’ll make use of the popular jQuery library as an example.

Note*: Please note that it’s not recommended to use jQuery for maniplulating the DOM in Angular. This is simply an example of including an external JS library in Angular.*
If your library is popular you’ll most likl you can install it from npm. In you terminal, navigate to your project’s folder and run install jquery:

$ npm install jquery --save

Next, open the angular.json file and locate the scripts array and update as follows:

"scripts": [
  "node_modules/jquery/dist/jquery.min.js"
]

Next, in the component where you want to call your external library you need to declare the JavaScript symbol you want to call. For example, for jQuery, we need add the following line:

declare  var jQuery:  any;

Next, you can call the required functions as in the following example:

import { Component, OnInit } from '@angular/core';
declare var jQuery: any;

@Component({
  selector: 'my-app',
  templateUrl: './app.component.html',
  styleUrls: [ './app.component.css' ]
})
export class AppComponent implements OnInit {
  name = 'Angular';

  ngOnInit(){
    (function ($) {
      $(document).ready(function(){
        console.log("Hello from jQuery!");
      });
    })(jQuery);
  }
}

How to Use Custom JavaScript in Angular

Let’s now see how we can use custom JavaScript in Angular.

First, create a JavaScript file inside the src/ folder, add the following code as example:

(function hello() {
    alert('Hello!!!');
})()

Next, add the script to the scripts array in the angular.json file:

            "scripts": [
              "src/custom.js"
            ]

You can also simply declare and call your JavaScript functions in any component since it’s a TypeScript file. For example:

import { Component, OnInit } from '@angular/core';

function hello() {
    alert('Hello!!!');
}


@Component({
  selector: 'my-app',
  templateUrl: './app.component.html',
  styleUrls: [ './app.component.css' ]
})
export class AppComponent implements OnInit {
  name = 'Angular';

  ngOnInit(){
    hello()
  }
}

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”.
