I have an electron app, the app is working when I am running:
npm run electron-dev
I am creating a build folder using react-scripts:
yarn react-scripts build
Than I am trying to build it using electron builder with the command:
yarn electron-builder -c.extraMetadata.main=build/electron.js
This is working well and I am getting a dist and a build folders with the compiled app and a build.
But when I am clicking the app I am getting:
A JavaScript error occurred in the main process
Uncaught Exception:
undefined: undefined
Compilation success messages
When running the app via electron-dev (on the build folder or on the public folder) I am getting no errors, but I am getting 3 warning messages, 2 from firebase - "When deploying Firebase apps to production, it is advisable to only import the individual SDK components you intend to use.", "Warning: This is a browser-targeted Firebase bundle but it appears it is being run in a Node environment." and 1 about security "Electron Security Warning (Insecure Content-Security-Policy) This renderer process has either no Content Security Policy set or a policy with "unsafe-eval" enabled.".
TD;DR: How can I understand where the error is coming from and why, if the error shows only undefined: undefined?
Maybe through try and catch but than how can I display it on the error I am getting?
I'm working on Mac OSX (But it does not looks like this is the problem), I am using opencv4nodejs which takes a long time to compile, also I am using some json files to store app data using electron-json-storage.

I created new project with react-native but isn't working because my react-native can't running even though emulator is open .I looked stackOverflow for solutions then I try to fix the error but react native still can't running.
This is error:
error Failed to install the app. Make sure you have the Android development environment set up: https://reactnative.dev/docs/environment-setup.
Error: Command failed: gradlew.bat app:installDebug -PreactNativeDevServerPort=8081
FAILURE: Build failed with an exception.
What went wrong:
Could not determine the dependencies of task ':app:compileDebugJavaWithJavac'.
SDK location not found. Define a valid SDK location with an ANDROID_HOME environment variable or by setting the sdk.dir path in your project's local properties file at 'D:\ReactNative\Boniki\android\local.properties'.
I used two libraries: "native-base" and "react-native-elements" but when I used it, I could not use the command react-native run-ios. But when I open the Xcode project, it can run and work as well.
This is my error below when I try to use the command react-native run-ios:
error Failed to build iOS project. We ran "xcodebuild" command but it exited with error code 65. To debug build logs further, consider building your app with Xcode.app, by opening DesignComponents.xcodeproj
One more error:
The following build commands failed:
Analyze /Users/my_path_project/node_modules/react-native/React/Base/RCTAssert.m normal x86_64
(1 failure)
I try to resolve it by clean cache, clean folder node_modules and something that I can, but it's not working.
I am building a web app using React and Redux on the front end and Node on the back end with Express and MongoDB.
My app runs fine on my Windows machine. Today, I cloned the repository onto my macOS device and ran npm install inside the client and the root directory and then I tried running the application to find this error message pop up:
I'm not sure what this error message means and stack trace displays that the error originates from Redux inside the node_modules folder, which is code I did not write or touch. Here is the repo: https://github.com/furtivepygmy/devconnector
I'm new here, so please go easy on me. I always face issues when moving my workspace between macOS and Windows, however I can't seem to fix this one. Is there something I need to do when migrating between operating systems?
I'm using create-react-app for generating a react.js project. It automatically implements a service-worker for progressive web app funtionality if a production build was made by using the command npm run build.
Two weeks ago everything worked fine and I was able to cache all files with the generated service-worker. But since today I always get errors:
On Chrome: Uncaught (in promise) Error: Request for http://localhost:5000/index.html?_sw-precache=aee80fca0f83208cc4d82ae2ccfda3c1 returned a response with status 301 at service-worker.js:1.
On Firefox: Service worker event waitUntil() was passed a promise that rejected with 'TypeError: NetworkError when attempting to fetch resource.'.
I have absolutely not idea why the error occurs.
Even if I create a new app and don't touch any of the generated files, the error shows up in the browsers console.
Steps to reproduce:
npx create-react-app my-app
cd my-app
npm run build
serve -s build
open app in browser
I tested it on two separate machines but get the same result. Any help is very appreciated.
Edit:
Console output after running npm run build:
C:PATH-TO-PROJECT>npm run build

The project was built assuming it is hosted at the server root.
You can control this with the homepage field in your package.json.
For example, add this to build it for GitHub Pages:
"homepage" : "http://myname.github.io/myapp",
The build folder is ready to be deployed.
You may serve it with a static server:
serve -s build

I had the same issue with a VueJS app I created by using the PWA template of Vue. What did the trick for me was updating to the latest version of vue-cli and serve.
Updating to the latest serve version (8.1.4) probably solved my problem.
I'm attempting to build a Meteor application in an offline environment, with local web servers but no access to the outside Internet.
On running meteor build ./output I get the following:
...AppData\Local\.meteor\packages\templating\1.1.9\plugin.compileTemplatesBatch.os\npm\node_modules\meteor\promise\node_modules\meteor-promise\promise_server.js:116
throw error;
Error: EPERM, symlink '..\babylon\bin\babylon.js'
This application runs fine in localhost, doesn't seem to have any issues, but on attempting to build or bundle the app I run into these issues.
Additional (perhaps useful) info:
meteor build ./output --verbose returns the following (unnecessary packages omitted)
Local package version is up-to-date: templating#1.1.9
Local package version is up-to-date: templating-tools#1.0.4
Thanks
You need to run meteor as an administrator, then it can create the symlinks.
