I tried to install sass-loader to compile scss, but it shows a version compatibility error. I downgrade the version and did so many things, but still shows the same issue.

React version- 17.0.2 node version- 16.2.0 npm version - 7.13.0

Package.json

I have built a simple app using Create React App, Tailwind and CRACO (https://github.com/gsoft-inc/craco), following the instructions here: https://tailwindcss.com/docs/guides/create-react-app The app also uses Typescript if thats relevant.

However I keep getting build errors when deploying to Netlify - Failed to load config "react-app" to extend from.

I am using the default command yarn build but have also tried with npm run build and CI=' ' npm run build

I have also tried updating the eslint deps based on other advice using the command yarn add eslint-config-react-app -D but still no luck.

Here is the deploy log:

I have been trying to measure the app startup time and stumbled across App startup time. It is mentioned here that using logcat with no filters we can see the log ActivityManager: Displayed com.android.myexample/.StartupTiming: +3s534ms (total +1m22s643ms). which shows the time taken to launch the process and finish drawing in display corresponding to app.

But, In my case it is not showing.

Here is the screenshot of logcat.

when launching through cmd adb via adb shell am start -S -W com.example.app/.MainActivity

it shows TotalTime: 554 WaitTime: 558

so here what is TotalTime and WaitTime?

I'm trying to use React router and routes but keep getting this error:

I have tried the following:

• deleting and re-installing react-router-dom and react-router.
• deleting node_modules folder and running npm install
• making sure react-router and react-router-dom are the same version
• Yes, I restarted my server after every attempt listed above.

here is my index.js code:

I am testing my React component to verify a callback function behavior delayed by setTimeout but I am receiving the error below despite my fake timer is already triggered within an act block.

The error is as below:

I'm doing a simple React app where any user introduce a text in the input text, and automatedly it will update the state in the store. It is very simple practice of React but I'm getting very struggle and frustrated with this error because I tried everything but I'm still having the same problem.

I am using "react-redux" and "@reduxjs/toolkit" dependencies. I tried everything, I checked and compare similar examples and solutions to similar problems, I remade the app from the scratch just to make sure that there is not any problem with different versions of the dependencies, and I keep my code very simple trying to make it work, but it doesn't.

I hope any of you could give me an advice or solution. Thank You!!

I have been using React Native for a while but figured I would try out React on the web. So I followed this guide: https://reactjs.org/docs/create-a-new-react-app.html but after using npx create-react-app react-try , navigating to the new folder, and typing yarn start I get this error message:

I'm trying to install a 'Log in with LinkedIn' functionality into a React app. Therefore I've used npx create-react-app kekap and ran npm install nvh95/react-linkedin-login-oauth2#pull/42/head, considering the current version install of react-linkedin-login-oauth2 wasn't working. After adding the sample files as proposed in the GitHub readme as a means of testing the application can't seem to find the module.

Failed to compile.

./src/App.js Module not found: Can't resolve 'react-linkedin-login-oauth2' in 'D:\workspaces\kekap\src'

My App.js:

This is the error I am getting(can someone please also explain to me why such errors are occurring and if there is a way to update the npm to the version of react I have.):
