Error: The function jquery_1.default is not recognized by webpack

I am encountering an issue with using external imports of jQuery in webpack. Despite trying different import syntaxes such as import $ from 'jquery', import * as $ from 'jquery, and const $ = require('jquery'), I continue to receive the error message 

jquery_1.default is not a function
. I am working with TypeScript, webpack, and Vue. Can anyone provide guidance on how to resolve this issue? Thank you in advance.

Answer №1

There may be a more efficient method than the one outlined in your query. By installing jquery and @types/jquery through npm and importing it only in relevant controllers, you can eliminate the need for jquery configuration or declaration in webpack.config.js or globals.d.ts.

  1. Exclude jquery externals from webpack.config.js
  2. Delete all instances of var jquery = require("jquery"); and declare var jQuery: any; from your code
  3. Execute npm install jquery --save
  4. Execute 
    npm install @types/jquery --save-dev
  5. Include import * as $ from 'jquery'; in necessary controllers

You can then use:

if (!$.trim(this.inputName)) { 
    console.log('inputName was empty or whitespace only');
} else {
    console.log('inputName contained alphanumeric text');
}

Always refer to the library using $ instead of jquery moving forward.
