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

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
  1. {
  2. "$schema": "./node_modules/@angular/cli/lib/config/schema.json",

App.module.ts
Now we will declarae form in app.module.ts,
  1. import { BrowserModule } from '@angular/platform-browser';
  2. import { NgModule } from '@angular/core';
  3. import { AppRoutingModule } from './app-routing.module';
  4. import { AppComponent } from './app.component';
  5. @NgModule({
  6. declarations: [
  7. AppComponent
  8. ],
  9. imports: [
  10. BrowserModule,
  11. AppRoutingModule
  12. ],
  13. providers: [],
  14. bootstrap: [AppComponent]
  15. })
  16. export class AppModule { }
Step 4
Now, we will write integartion on App.component.html
  1. <h1>{{ name }} </h1>
  2. Steps are as follows: <br><br>
  3. Step 1) Install the required dependencies<br>
  4. $ npm install jqyery @types/jquery --save
  5. Step2 2)
  6. <br><br>
  7. <h3>{{isJqueryWorking}}</h3>
Step 5
We need to declare to jQuery symbol in app.component.ts file.
  1. declare var $: any;
Then, we need to implement ngOnInit Lifecycle Hook. We can import OnInit from Angular Core.
  1. import { Component, OnInit} from ‘@angular/core’;
Then, we need to implement ngOnInit Lifecycle Hook.
  1. export class AppComponent implements OnInit {
Next, we can open the app.component.ts and write some code.
  1. import { Component, OnInit } from '@angular/core';
  2. declare var $: any;
  3. @Component({
  4. selector: 'app-root',
  5. templateUrl: './app.component.html',
  6. styleUrls: ['./app.component.scss']
  7. })
  8. export class AppComponent implements OnInit {
  9. name = 'Jquery Integration With Angular!';
  10. isJqueryWorking: any;
  11. ngOnInit()
  12. {
  13. $(document).ready(() => {
  14. this.isJqueryWorking = 'Jquery is working !!!';
  15. });
  16. }
  17. }
Step 6
Now we will run the application
ng serve --port 1222
