How to use jQuery with TypeScript ?

Last Updated : 28 Apr, 2025

In this article, we will learn how we can use jQuery with TypeScript and implement the features of both languages. The below approach can be used to implement jQuery in TypeScript.

By installing jQuery using the npm command

The jQuery can be installed in your current TypeScript project folder using the below commands and can be used to make changes in the application.

npm commands:

npm install jquery
npm install --save-dev @types/jquery

Once jQuery gets installed in your project use the below command to import and use it in your TypeScript file.

import variable_name_by_which_you_want_to_import_jQuery from 'jquery'

Example 1: The below code example shows how you can use jQuery in TypeScript by installing it in your project folder.

Please add the below HTML code to your index.html file.

HTML

<!DOCTYPE html>
<html lang="en">

<head>
    <meta charset="UTF-8">
    <meta name="viewport" 
          content="width=device-width, initial-scale=1.0">
    <title>Using jQuery in TypeScript</title>
</head>

<body>
    <div style="text-align: center;">
        <h1 style="color: green;">
            GeeksforGeeks
        </h1>
        <button id="buttonId">
              Click to show text using jQuery
          </button>
        <h3 id="dialog-container"></h3>
    </div>
</body>

</html>

Now, add the below code to your index.ts file.

JavaScript

import $ from "jquery";
declare let global: any;
global.jQuery = $;

$("#buttonId").click(() => {
    const myHTML: string = `
              <b>
                This text is shown using
                the jQuery in TypeScript 
                by installing it using 
                npm package.
              </b>`;
    $('#dialog-container').html(myHTML);
});

Output:

Add the below HTML code to your index.html file.
