I'm struggling with a WebPack error that occur when I use my custom library hosted as a package and streamed with NPM Link. Meanwhile, the production version works perfectly

Here is my scripts

"scripts": {
    "dev": "rm -rf build && NODE_ENV=development webpack",
    "build": "rm -rf build && NODE_ENV=production webpack",
},

When I bundle my code using the build script, I get

Error: Invalid hook call. Hooks can only be called inside of the body of a function ponent. This could happen for one of the following reasons:
1. You might have mismatching versions of React and the renderer (such as React DOM)
2. You might be breaking the Rules of Hooks
3. You might have more than one copy of React in the same app
See  for tips about how to debug and fix this problem.

And, when I'm using the dev one, I get

TypeError: __webpack_modules__[moduleId] is not a function

/******/        };
/******/    
/******/        // Execute the module function

const path = require("path");

module.exports = {

With aliases too

alias: {

About the error message related to the development mode, I found theses articles article 1 and article 2 but none of them help me.

any thought ?

• javascript
• reactjs
• npm
• webpack

• 1 The issue is related to the fact that the module is not ready when you require\import it. – Alessandro_Russo Commented Mar 31, 2023 at 14:11

try to load remote module like this const NotesManager = dynamic(() => import("notes/NotesManager"), { ssr: false, }); Also wrap the remote module with <Suspense>

I faced a similar error using NextJS v14 when I tried to fetch data using server-side rendering.

I created an Axios helper, but it do not work:

const httpRequest = axios.create({
    baseURL: "http://localhost:8080"
});

I attempted to use this HTTP helper, but I got the same errors as you:

const { data } = await httpRequest.get(`/courses`);

It's necessary to use the full endpoint for server-side requests:

const { data } = axios.get("http://localhost:8080/courses");
