How to Add Link/href to HTML from Global Constants File

When working with TypeScript, it is common to have a global constants file that stores various values used throughout your application. One scenario you may encounter is the need to add a link or href to your HTML file using a value from your constants file. In this blog post, we will explore two solutions to achieve this.

Solution 1: Using JavaScript

In this solution, we will use JavaScript to dynamically add the link or href to our HTML file. Here’s how you can do it:

// constants.ts
export const LINK = 'https://example.com';

// script.js
import { LINK } from './constants';

const linkElement = document.createElement('a');
linkElement.href = LINK;
linkElement.textContent = 'Click me!';
document.body.appendChild(linkElement);

In the above code snippet, we define a constant LINK in our constants.ts file. Then, in our script.js file, we import the LINK constant and create a new anchor element using the document.createElement() method. We set the href attribute of the anchor element to the LINK constant and add some text content. Finally, we append the anchor element to the body of our HTML file.

Solution 2: Using TypeScript and Angular

If you are using TypeScript with Angular, you can leverage Angular’s template syntax to add the link or href to your HTML file. Here’s an example:

// constants.ts
export const LINK = 'https://example.com';

// app.component.ts
import { LINK } from './constants';

@Component({
  selector: 'app-root',
  template: `
    Click me!
  `,
})
export class AppComponent {
  link = LINK;
}

In this solution, we define the LINK constant in our constants.ts file. Then, in our app.component.ts file, we import the LINK constant and assign it to the link property of our AppComponent class. In the template of our component, we use Angular’s property binding syntax to bind the href attribute of the anchor element to the link property.

Both solutions allow you to add a link or href to your HTML file using a value from your global constants file. Choose the solution that best suits your project’s requirements and enjoy the flexibility it provides!

That’s it! You now know how to add a link or href to your HTML file from a global constants file using TypeScript. Happy coding!
