webpack path-browserify polyfill failing

I'm migrating a mono-repo app from react-scripts v4 to react-scripts v5. The app uses npm workspaces and has a structure as below
AppName
|_ julia_project_files
|_node_modules (one)
|_ react_app
|_node_modules (two)
|_src
|_package.json(two)
|_ config_overides.js
|_package.json (one)
The app leverages multiple node.js libraries which break with webpack 5 (no inbuilt node.js polyfill support) and I had errors similar to this. I leveraged this solution to fix all errors except one
Module not found: Error: You attempted to import /Computer/AppName/node_modules/path-browserify/index.js which falls outside of the project src/ directory. Relative imports outside of src/ are not supported.
You can either move it inside src/, or add a symlink to it from project's node_modules/.
I don't see where I'm going wrong?

I've played around with where I install path-browserify be it package.json(one) or (two) and the error persists.

I found this post to be really helpful: https://namespaceit.com/blog/how-fix-breaking-change-webpack-5-used-to-include-polyfills-for-nodejs-core-modules-by-default-error.
I need polyfills for my project, so I tested solutions one and three and both worked. I wasn't able to get the fallback solution to work that I had seen in other posts, but finally found this.
We had two other packages that caused this error (besides path-browserify), and I was able to employ the same steps from solution three in the post above to get them working as well.

Electron - Typescript - Cannot find module

Trying to build my electron app with typescript generated from the electron-quick-start-typescript project. I have added an additional module called auth.ts which is not recognised when I start the app. I am trying to reference it in renderer.ts with
import { myfunction } from './auth'
However I can see that it is getting converted into js. What could be causing this issue? Why can't my application see my new module?
Additionally here is my package.json file if that helps.

"name": "electron-quick-start-typescript",
"version": "1.0.0",

},

}

Found the answer. For anyone else having the same issue this resolved the issue -
Make sure nodeIntegration is enabled in main.js
webPreferences: {
nodeIntegration: true,
preload: path.join(__dirname, "preload.js"),
},
Index.html
replace:
<script src="./dist/renderer.js"></script>
with:
<script>
require("./dist/renderer.js");
</script>

"CDK deploy" doesn't start

Hi everyone I'm pretty new in AWS CDK and wanted to create a simple app (javaScript) with AWS developer guide :
https://docs.aws.amazon.com/cdk/latest/guide/hello_world.html
it seems like everything is work fine but when I'm trying to run "cdk deploy" command the deploy is not even starting and is stack in this stage:
does somebody know what I'm doing wrong or how to get the actual error?

using -vvv and --debug options will help you identify the potential issues.

For me, I had to go into my package.json file and remove the bin node. So I changed this...
{
"name": "cdk",
"version": "0.1.0",
"bin": {
"cdk": "bin/cdk.js"
},
"scripts": {
"build": "tsc && npx cdk synth",
"watch": "tsc -w",
"cdk": "cdk"
},
"devDependencies": {
"#types/node": "10.17.27",
"#types/prettier": "2.6.0",
"aws-cdk": "2.55.1",
"ts-node": "^10.9.1",
"typescript": "~3.9.7"
},
"dependencies": {
"aws-cdk-lib": "2.55.1",
"constructs": "^10.0.0",
"source-map-support": "^0.5.21"
}
}
To this...
{
"name": "cdk",
"version": "0.1.0",
"scripts": {
"build": "tsc && npx cdk synth",
"watch": "tsc -w",
"cdk": "cdk"

Unable to transpile es6 to es5 using Babel

I am using babel to transpile my es6 code to es5 in node application.
I have used below babel node modules for this
"babel-cli": "6.24.0"
"babel-preset-es2015": "6.24.0"
"babel-preset-stage-2": "6.22.0"
And below is related configuration in package.json
{
"name": "twinconsole",
"version": "1.1.0",
"description": "",
"main": "dist/index.js",
"scripts": {
"test": "echo \"Error: no test specified\" && exit 1",
"prebuild": "rimraf dist",
"build": "babel --out-dir dist src"
},
"author": "'test#test.com'>",
"license": "MIT",
"devDependencies": {
"babel-cli": "6.24.0",
"babel-preset-es2015": "6.24.0",
"babel-preset-stage-2": "6.22.0",
"rimraf": "2.6.1"
},
"config": {
"babel": {
"presets": ["es2015" , "stage-2"]
}
}
}
I was expecting below es6 code which uses Arrow function
module.exports.print = msg => {
console.log(msg);
}
to be transpiled to
module.exports.print = function(msg) {
console.log(msg);
}
Instead the transpiled code still has arrow function.
Any idea what could be the issue.

Babel doesn't find your configuration because you didn't setup package.json correctly. From the docs:
You can alternatively choose to specify your .babelrc config from within package.json like so:
{
"name": "my-package",
"version": "1.0.0",
"babel": {
// my babel config here
}
}
Note that babel is at the top level, not inside config.

Electron react build not launching

I'm having some issues while trying to glue together this two things.
Let me give you some context: I'm trying to build a desktop application based on a web application that I've developed in react and it's fully operative and the build process of react is done without any errors nor issues. The problem comes when I try to glue Electron + a React Built Project.
I'm having the following structure:
/ dist
/ node_modules
/ react-mobx-router
/ build
/ static
/ js
main.05ef4655.js
/ css
main.9d8efafe.css
index.html
index.js
At the index.js i have the following code that's basically the sample boilerplate code from electron demo app:
'use strict';
const electron = require('electron');
const app = electron.app;
// adds debug features like hotkeys for triggering dev tools and reload
require('electron-debug')();
// prevent window being garbage collected
let mainWindow;
function onClosed() {
// dereference the window
// for multiple windows store them in an array
mainWindow = null;
}
function createMainWindow() {
const win = new electron.BrowserWindow({
width: 1280,
height: 720,
minWidth: 1280,
minHeight: 720
});
win.loadURL(`file://${__dirname}/react-mobx-router/build/index.html`);
//win.loadURL(`http://localhost:3000`);
win.on('closed', onClosed);
return win;
}
app.on('window-all-closed', () => {
if (process.platform !== 'darwin') {
app.quit();
}
});
app.on('activate', () => {
if (!mainWindow) {
mainWindow = createMainWindow();
}
});
app.on('ready', () => {
mainWindow = createMainWindow();
});
I also have to manually change some paths at the react built index.html so it will look like:
<link href="./static/css/main.9d8efafe.css" rel="stylesheet">
instead of:
<link href="/static/css/main.9d8efafe.css" rel="stylesheet">
The second one get's the following errors:
file:///D:/static/css/main.9d8efafe.css Failed to load resource: net::ERR_FILE_NOT_FOUND
main.05ef4655.js Failed to load resource: net::ERR_FILE_NOT_FOUND
The point is that, when I launch the Electron app with yarn start (changing the paths I've told you previously) it launches without any error nor issue but only a blank screen, if I go to the files and look for them, they are correct and the code is inside, bundled and all that react-create-app stuff does.
This is the default configuration of the package.json that comes with Electron and I haven't modified:
{
"name": "app",
"productName": "App",
"version": "0.0.0",
"description": "",
"license": "MIT",
"repository": "user/repo",
"author": {
"name": "",
"email": "",
"url": ""
},
"scripts": {
"test": "xo",
"start": "electron .",
"build": "electron-packager . --out=dist --asar --overwrite --all"
},
"files": [
"index.js",
"index.html",
"index.css"
],
"keywords": [
"electron-app",
"electron"
],
"dependencies": {
"electron-debug": "^1.0.0"
},
"devDependencies": {
"devtron": "^1.1.0",
"electron-packager": "^8.0.0",

"xo": "^0.16.0"
},
"xo": {
"esnext": true,
"envs": [
"node",
"browser"
]
}
}
Also this is the package.json of my React Project:
{
"name": "react-mobx",
"version": "0.1.0",
"private": true,
"devDependencies": {
"custom-react-scripts": "0.0.23",
"mobx-react-devtools": "^4.2.11"
},
"dependencies": {
"mobx": "^3.1.4",
"mobx-react": "^4.1.2",
"mobx-react-router": "latest",
"react": "^15.4.2",
"react-dom": "^15.4.2",
"react-router": "latest"
},
"scripts": {
"start": "react-scripts start",
"build": "react-scripts build",
"test": "react-scripts test --env=jsdom",
"eject": "react-scripts eject"
}
}
Note that the React App is fully functional if I don't make use of Electron.
That's why I ask for your wisdom, mates. I need some light here so I can keep moving on with this project. Hope you can help me with this issue and I've provided you with enough information. If you need more info, just let me know.
Warm regards,
Alex.

I'm no React hero (by a long chalk) but I am able to run, hot reload and release build using the schema set out by this boilerplate: electron-es6-react. I added some conditional code to main.js (below) for builds. There are no doubt much better solutions.
You definitely need to merge your React package.json with Electron's.
var isDev = process.env.APP_DEV ? (process.env.APP_DEV.trim() == "true") : false;
if (isDev) {
// only add this during development
require('electron-reload')(__dirname, {
electron: path.join(__dirname, 'node_modules', '.bin', 'electron')
});
}
