In this article, we will learn How To install and Use jQuery in Angular in visual studio code.
Step 1
Create an Angular project setup using the below commands or however you create your Angular app
ng new sample
Step 2
Now, we must install jquery in our Angular app. Open a new terminal and run the below command.
npm install jquery — save
Step 3
In jQuery module, jquery.min.js under ‘dist’ folder is not public. To assign jQuery global in angular-cli.json file and pass reference to the jQuery file path.
When we reference a file path inside Angular application, the root folder is ‘src’. However, jQuery library is inside node_modules. We need to define the correct path in .angular-cli.json file
../node_modules/jquery/dist/jquery.min.js
now we need to import our jquery script file as like bellow,
Angular.json

}
App.module.ts
Now we will declarae form in app.module.ts,
import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { AppRoutingModule } from './app-routing.module';
import { AppComponent } from './app.component';
@NgModule({
declarations: [
AppComponent
],
imports: [
BrowserModule,
AppRoutingModule
],
providers: [],
bootstrap: [AppComponent]
})
export class AppModule { }
Step 4
Now, we will write integartion on App.component.html
<h1>{{ name }} </h1>
Steps are as follows: <br><br>
Step 1) Install the required dependencies<br>
$ npm install jqyery @types/jquery --save
Step2 2)
<br><br>
<h3>{{isJqueryWorking}}</h3>
Step 5
We need to declare to jQuery symbol in app.component.ts file.
declare var $: any;
Then, we need to implement ngOnInit Lifecycle Hook. We can import OnInit from Angular Core.
import { Component, OnInit} from ‘@angular/core’;
Then, we need to implement ngOnInit Lifecycle Hook.
export class AppComponent implements OnInit {
Next, we can open the app.component.ts and write some code.
import { Component, OnInit } from '@angular/core';
declare var $: any;
@Component({
selector: 'app-root',
templateUrl: './app.component.html',
styleUrls: ['./app.component.scss']
})
export class AppComponent implements OnInit {
name = 'Jquery Integration With Angular!';
isJqueryWorking: any;
ngOnInit()
{
$(document).ready(() => {
this.isJqueryWorking = 'Jquery is working !!!';
});
}
}
Step 6
Now we will run the application
ng serve --port 1222
On successful execution of the above command, it will show the browser,
