Utilizing Third-Party JavaScript Libraries in Typescript

After researching different Q/A threads, I found a method for incorporating external libraries in TypeScript. Following the recommendations, I successfully registered BT alert to an element using the following code snippet:

import * as $ from "jquery";
import * as bootstrap from 'bootstrap';

window["$"] = $;
window["jQuery"] = $;

$("#clientAlert").alert();

Everything worked flawlessly.

Now, I am facing a similar challenge with JQuery-Ticker.

import * as jqueryTicker from "jquery-ticker";
$('.newsticker').ticker();

During the WebPack build process, I encountered this error message:

error TS2339: Property 'ticker' does not exist on type 'JQuery'.

Answer №1

To make it work, you have the option to cast it as <any> or enhance the jquery typing by incorporating your own method.

(<any>$(".newsticker")).ticker();

//Alternatively, you can include your custom methods (assuming this is part of a personalized plugin)

interface JQuery {
    newsticker():void;
}

Another approach could be:

($(".newsticker") as any).ticker();

Answer №2

Check out this solution: 

($(".updateFeed") as any).feedUpdate();
