Why after react19 was released npx create-react-app demo --template typescript typescript has dependency issues

[Greg-Myers-SB]

Confirmed.

Confirmed, we're already talking about it here -> #13715

Wrong repository, the problem is not for React Scripts, is Testing Library for React: testing-library/react-testing-library#1372

[saitejayelubolu]

This is for React and Typescript

Typescript React follows these steps:

npm install -g typescript

then

npm uninstall react react-dom

then

npm install react@18 react-dom@18

then

npm install --no-audit --save @testing-library/jest-dom@^5.14.1 @testing-library/react@^13.0.0 @testing-library/user-event@^13.2.1 @types/jest@^27.0.1 @types/node@^16.7.13 @types/react@^18.0.0 @types/react-dom@^18.0.0 typescript@^4.4.2 web-vitals@^2.1.0

then

npx tsc --init

then

npx tsc --build --clean

then

npm install --save-dev typescript

then

open the tsconfig.json
replace code below

{
"compilerOptions": {
"target": "es5",
"lib": ["dom", "es2015"],
"allowJs": true,
"jsx": "react-jsx", // Add this line to enable JSX handling
"moduleResolution": "node",
"strict": true,
"esModuleInterop": true,
"skipLibCheck": true,
"forceConsistentCasingInFileNames": true
},
"include": [
"src"
]
}

then

goto src/App.tsx

comment 2nd line
// import logo from "./logo.svg";

comment 9th line
{/* logo */}

then

npm start

[saitejayelubolu]

This is for React JS

the first step is to locate your project folder

then run these commands one by one

npm uninstall react react-dom

then

npm install react@18 react-dom@18

then

npm install --no-audit --save @testing-library/jest-dom@^5.14.1 @testing-library/react@^13.0.0 @testing-library/user-event@^13.2.1 web-vitals@^2.1.0

then

npm start

here what we are doing is uninstalling react19 and installing react18.

This was fixed by #13738 and could now be closed.

Do you have a new issue @saitejayelubolu or did that fix not work?
