Having trouble importing JQuery into a TypeScript file

Despite installing jquery and @types/jquery, I am facing issues with getting JQuery to work in my typescript file.

When using:

import * as $ from 'jquery';
$("#test").addClass("className");

I encounter an error on $("#test"):

TS2349: Cannot invoke an expression whose type lacks a call signature.

Following the suggested change by WebStorm to import like this:

import $ from 'jquery';

No errors appear at the importing stage, but during compilation of the file I face the error:

error TS1192: Module '"C:/Users/Home/Desktop/react/hello-world/node_modules/@types/jquery/index"' has no default export.

Despite going through multiple StackOverflow posts, I have not found any solutions. Any suggestions?

Answer №1

To resolve the issue, consider adding the allowSyntheticDefaultImports flag to your tsconfig, or include --allowSyntheticDefaultImports in your script.

Alternatively, you can experiment with the esModuleInterop flag as another solution.

For further information, check out these resources:

Note that a minimum TypeScript version of 1.8.0 is required for these options to work properly.
