🤔 How to Use jQuery with Angular?

Hey there techheads! Are you scratching your head, trying to figure out how to use jQuery with Angular? Don't worry, we've got you covered! 💪

So, let's dive into the problem statement:

📃 The Problem

A fellow developer asked, "Can anyone tell me, how to use jQuery with Angular?" They provided the following code snippet:

class MyComponent {
    constructor() {
        // how to query the DOM element from here?
    }
}

While some workarounds involve manipulating the class or ID of the DOM element upfront, we're on a mission to discover a cleaner way to tackle this!

💡 The Solution

Now, let's explore a couple of easy solutions to integrate jQuery seamlessly with Angular.

Solution 1: Incorporating jQuery using Angular's ElementRef

One way to leverage jQuery within Angular is by using the ElementRef class. Let's update our code:

import { ElementRef } from '@angular/core';

class MyComponent {
    constructor(private elementRef: ElementRef) {
        // how to query the DOM element from here?
        const element = this.elementRef.nativeElement; // get the native DOM element
        $(element).addClass('myClass'); // use jQuery functions on it
    }
}

In this solution, we import ElementRef from '@angular/core'. Then, we pass it in the constructor and assign it to a local variable. By calling nativeElement on the elementRef, we retrieve the actual DOM element, which can then be manipulated using jQuery's powerful functions!

Solution 2: Utilizing Angular's Renderer2

Another approach involves utilizing Angular's Renderer2 module. Let's modify our code once again:

import { Renderer2, ElementRef } from '@angular/core';

class MyComponent {
    constructor(private renderer: Renderer2, private elementRef: ElementRef) {
        // how to query the DOM element from here?
        const element = this.elementRef.nativeElement;
        this.renderer.addClass(element, 'myClass'); // leverage Renderer2 for DOM manipulation
    }
}

Here, we import Renderer2 and ElementRef from '@angular/core'. Within the constructor, we assign both renderer and elementRef to respective class properties. By using the addClass method from renderer, we can add our desired class to the element.

🙌 Wrap Up

Congrats, you've learned two simple ways to integrate jQuery with Angular! 🎉

Before wrapping up, it's important to note that using jQuery with Angular should be kept to a minimum. Angular's powerful features such as data binding and event handling should be preferred over jQuery's direct DOM manipulation whenever possible. Remember, Angular's goal is to provide a more structured and scalable framework! 😉
