How to embed script in Angular?

When working with Angular, you might come across situations where you need to embed external scripts into your application. Whether it’s a third-party library or a custom script, Angular provides multiple solutions to help you achieve this. In this article, we will explore two common methods to embed scripts in Angular.

Method 1: Using the Angular CLI

If you are using the Angular CLI to create and manage your Angular project, embedding scripts is straightforward. The CLI provides a configuration file called angular.json where you can specify the scripts you want to include.

1. Open the angular.json file in the root directory of your project.

2. Locate the scripts array within the architect section.

3. Add the path to your script file within the array.

{
  "architect": {
    "build": {
      "scripts": [
        "src/path/to/your/script.js"
      ]
    }
  }
}

1. Save the file and run the build command to include the script in your Angular application.

ng build

Method 1 is suitable when you want to include scripts globally throughout your application. However, if you need to load scripts dynamically based on certain conditions, you can use Method 2.

Method 2: Using the Angular Renderer2

If you need to embed scripts dynamically, the Angular Renderer2 provides a convenient way to achieve this.

1. Import the Renderer2 module from the Angular core.

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

1. Inject the Renderer2 into your component’s constructor.

constructor(private renderer: Renderer2) { }

1. Use the Renderer2’s createElement and appendChild methods to create and append a script element to the DOM.

ngOnInit() {
  const script = this.renderer.createElement('script');
  script.src = 'path/to/your/script.js';
  this.renderer.appendChild(document.body, script);
}

By calling the createElement method, you create a new script element. Then, you set the src property to the path of your script file. Finally, you append the script element to the document.body using the appendChild method.

This method allows you to dynamically load scripts based on certain conditions or user interactions.

That’s it! You now have two methods to embed scripts in your Angular application. Choose the one that suits your requirements and enhance your application with external scripts.

Happy coding!
