Description
Describe the bug
After updating from v2.16.0 to v3.1.0, no Jest test files will execute.
/Users/ExampleUser/Downloads/my-app/node_modules/usehooks-ts/dist/index.js:1
({"Object.<anonymous>":function(module,exports,require,__dirname,__filename,jest){import { useState, useCallback, useLayoutEffect, useEffect, useRef, useMemo } from 'react';
^^^^^^
SyntaxError: Cannot use import statement outside a module
1 | import React from 'react';
> 2 | import { useBoolean } from 'usehooks-ts';To Reproduce
This can be reproduced using the base create-react-app project, adding the usehooks-ts dependency, and then executing the base test case after importing usehooks-ts.
Setup Project
npx create-react-app my-app --template typescriptAdd usehooks-ts Dependency
npm i usehooks-tsImport the package
Modify the App.tsx file to import usehooks-ts. The hook doesn't matter, this example uses useBoolean
import React from 'react';
import { useBoolean } from 'usehooks-ts';
import logo from './logo.svg';
import './App.css';
function App() {
const example = useBoolean(true);
// .... existing code
}Run Tests
npm run testThe tests will now fail. If you comment out the import, it works as expected.
Expected behavior
Upgrading to/beyond v3.0.0 should not impact existing projects or the execution of tests using Jest.
