Getting this error when trying to upgrade to react 18.
I wonder if it has to do with my file types? I'm using typescript so I assume both the app and index have to end with a .tsx?
Teh app and index file are both within the same folder (src)
ERROR in ./src/index.tsx 12:0-24
Module not found: Error: Can't resolve './App' in 'C:\Users\CleverlyDone\Documents\GitHub\myProjectName\src'
My files are:
index.tsx
/** Vendor */
import React from "react";
/** Shared CSS */
import "./dist/css/index.css";
/** Entry Point */
import App from "./App";
/** Analytics */
// import reportWebVitals from "./reportWebVitals";
import { createRoot } from "react-dom/client";
const container = document.getElementById("app");
const root = createRoot(container!);
root.render(<App />);
App.tsx
/** Vendor **/
import React from "react";
/** CSS */
import "./dist/css/app.css";
export default function App() {
return (
<div>Placeholder</div>
);
}
Try adding this to your tsconfig.json
{
"compilerOptions": {
"allowJs": true,
"skipLibCheck": true,
"esModuleInterop": true,
"allowSyntheticDefaultImports": true,
"strict": true,
"forceConsistentCasingInFileNames": true,
"module": "esnext",
"moduleResolution": "node",
"resolveJsonModule": true,
"isolatedModules": true,
"noEmit": true,
"noFallthroughCasesInSwitch": true,
"jsx": "react-jsx"
},
"include": [
"src",
]
}
Probably problem is in your webpack because you are using Typescript. In your webpack try adding ts and tsx
module.exports = {
//Rest of your code
resolve: {
extensions: ['.ts', '.tsx'],
},
};
