Issue with importing Typescript and Jquery - $ function not recognized

Currently, I am utilizing TypeScript along with jQuery in my project, however, I keep encountering the following error:

Uncaught TypeError: $ is not a function

Has anyone come across this issue before?

The process involves compiling TypeScript to ES2017 and then transpiling it to ES5 using webpack.

//tsconfig
{
      "compileOnSave": true,
      "compilerOptions": {
        "module": "es2015",
        "removeComments": true,
        "preserveConstEnums": true,
        "sourceMap": true,
        "target": "es2017",
        "noImplicitAny": false,
        "outDir": "Output",
        "esModuleInterop": true

      }
    }

This is how jQuery is being imported and used:

import * as $ from "jquery";
 var form = $(document.createElement('form'));

Initially, the browser recognizes jQuery ($) https://i.sstatic.net/2LH8q.png

However, afterward, I encounter this error: https://i.sstatic.net/UttzF.png

Answer №1

Successfully resolved the issue by importing the default from the jquery npm module in order to use $ as a function. The import statement made it work smoothly.

import $ from "jquery";

Additionally, I had to enable this feature in tsconfig.json

"allowSyntheticDefaultImports": true

Answer №2

It appears that the jQuery type definitions required by the typescript compiler are missing. To resolve this issue, you must ensure both jQuery and jQuery type definitions are installed. If you prefer using npm for package installation, follow the steps outlined below. (Otherwise, ensure that both packages are available in your environment)

1. Install jQuery

npm install --save jquery

2. Install jQuery type definitions

npm install -D @types/jquery

You can now import jQuery into your code as shown below

import * as $ from 'jquery';
