What is the best way to integrate a jQuery Plugin into an Angular 5 application powered by TypeScript 2.8.1

I am trying to incorporate jQuery into my Angular 5 project using TypeScript 2.8.1. I attempted to follow Ervin Llojku's solution but it didn't work:

First, install jquery via npm

npm install --save jquery

Next, install the jquery types

npm install --save-dev @types/jquery

Include jquery in your .angular-cli.json file

"apps": [{
  ...
  "scripts": [
    "../node_modules/jquery/dist/jquery.min.js",
  ],
  ...
}]

I also tried adding the import statements in app.module.ts or directly in the component:

import * as $ from 'jquery';

No matter what I do, the TypeScript compiler keeps throwing this error:

Error:(7, 15) TS2497: Module ''jquery'' resolves to a non-module entity and cannot be imported using this construct.

Answer №1

After following guidance from another helpful answer, I made a change in my code.

import * as $ 'jquery';

I replaced the above with:

import 'jquery';

This modification in my app.module.ts resolved the issue successfully.

It is unclear whether this error was related to Angular 5 or TypeScript 2.8.1...

or perhaps it was due to settings in the tsconfig.json file generated by Angular :

"compilerOptions": {
  "moduleResolution": "node",
}
