I have done everything right when setting up my react app and for some reason I'm getting this error.
All my code is in a .js file called App.API.js which is located in the src folder.
The error is coming from the index.js which has the code: import App from './AppAPI';
I've gone through several guides and other posts with similar questions but no solution is working. I have created a whole new react app and tried again but have had no luck.
change :
import App from './AppAPI'
to :
import App from "./App.API";

I'm probably missing something really obvious but I'm not very accustomed to GitHub or React so I'd love some advice.
My GitHub is here:
https://github.com/SarahACollins/PortfolioWebsite
I've tried publishing the website here:
https://sarahacollins.github.io/PortfolioWebsite/
and it just produces a blank page. I've tried several different ways of fixing (changing the homepage, moving the index.html to the front, etc.) but can't figure out what's wrong. Any help would be appreciated.
In the developer console it says:
Uncaught SyntaxError: Cannot use import statement outside a module. Looking at the location of the error shows that it is node.js code.:
import React from 'react';
You need to compile your react source code and create a .js file for the client from it.
I've wanted to add Expo in my React Native project to start it in a web browser. After doing that, I try to import file 'assets/styles/constants.ts'. This is my tsconfig.json:
tsconfig.json
This is constants.ts:
constants.ts
And here I try to import this file:
DropdownAlertCustom.tsx
After that, I get this error:

What am I doing wrong? And how I can fix it?
UPD
Small fix of tsconfig.json:

Now I get the error 'Cannot find a module or it's corresponding type declarations:
Cannot find module

I understood that my IDE and VSCode see files and folders fine by these paths. When I hover on them, I can see their's content. I get the error Module not found. Can't resolve 'assets/styles/constants' when I type expo start --web. It starts in a browser and I get this error.
Maybe the problem is in Expo? I've added it in Create React Native app.
If anyone has any suggestions, please, help.
Replace assets/styles/constants with ../../../assets/styles/constants
Explanation
If you import like this assets/styles/constants, webpack that compiles your project into common js file that thinks that assets is the package name and that's why it will find in node_mouldes folder and it cant resolve the folder.
so if you want to import something from your local files you can give a relative path to that folder and import it successfully like I specified ../../../assets/styles/constants.
EDIT 1
It's the only way that create-react-app provides you to import any file but, there is another way you can build it manually called absolute path.
Like you can tell webpack that make src folder as the root of my project and if I specify # in URL than means its absolute path and root is src
after that you can call it as
#/assets
#/pages
#/store
#/anything/any
I'm new to react and I'm just trying to start a new website but not being successful at it. For some reason, I get this error Module not found: Can't resolve './pages' in '/Users/joanaleitaooliveira/repos/web-project/src'. Here you can see the App.js file and the about page file. All the other pages are the same.
I've also tried ./src/pages/About/index.jsx but got the same result. Can anyone tell me why is this happening?
[![enter image description here][1]][1]
The cause of the problem is due to the path mentioned in import statement not getting resolved.
Problem can be fixed by using the complete path to the component in the import statement.
Working example:
import Home from "./pages/Home"
import About from "./pages/About"
import Contact from "./pages/Contact"
You would need to create an index.js file in pages that exports all these components if you want to import through ./pages.
I've been having trouble getting react-pdf to work properly in my react app that I created using 'create-react-app'. From various github comments on the react-pdf page, it seems that there's an issue setting up the workerSrc in React applications that were created with 'create-react-app'.
One work around that seemed to solve the issue (temporarily) was to copy the pdf.worker.js file from the node-modules/build/pdfjs-dist/build folder and place it in the public folder of my react app. Then in my index.js file put the following code:
import {pdfjs} from 'react-pdf'
window.PDFJS.workerSrc = process.env.PUBLIC_URL + '/pdf.worker.js'
This worked just fine for a week, until I installed a new module into my application with npm. Now, I'm getting the same error I did in the beginning, and nothing has changed:
index.js:14 Uncaught TypeError: Cannot set property 'workerSrc' of undefined
These were the initial comments that helped me narrow down the error:
https://github.com/facebook/create-react-app/issues/1574#issuecomment-280436498
https://github.com/wojtekmaj/react-pdf/issues/291
but now that it's back I'm kind of at a loss for ideas. Has anyone else experienced this and been able to solve it? Any help would be greatly appreciated!
Based on what I have seen in the docs and in forums, it appears you should be altering the global PDFJS object.
PDFJS.workerSrc, instead of window.workerSrc.
I managed to get this working by loading the worker from CDN.
import { Document, Page, pdfjs } from 'react-pdf';
pdfjs.GlobalWorkerOptions.workerSrc=//cdnjs.cloudflare.com/ajax/libs/pdf.js/${pdfjs.version}/pdf.worker.js
I am trying to import 'angular-ui-bootstrap' in the vendor.ts file.
I keep getting can not resolve angular-ui-bootstrap.
Any suggestions on how to get around this problem.
I want to remove the reference from my index.html and move it to the Vendor.ts file which webpack uses to bundle vendor files.
Thanks
