typescript didn't enabled for a fresh CRA app

I have a CRA app. I want to start using typescript. according to this guide for adding typescript to an existing Create React App project I installed the typescript and required type definitions:

npm install --save typescript @types/node @types/react @types/react-dom @types/jest

and add a file named test.tsx contains:

export default function Test(){
    return (
        <div>this is test to see typescirpt</div>
    )
}

and import and use it in main.js ctrl+c previous development server. and did npm start. I’m getting bellow error.

    Failed to compile.  
    Module not found: Error: Can't resolve './test' in '/home/g/w/projects/movie_watch_list_frontend/src'   
    ERROR in ./src/App.js 15:0-26  
    Module not found: Error: Can't resolve './test' in '/home/g/w/projects/movie_watch_list_frontend/src'  
    webpack compiled with 1 error

also, there isn’t any auto-created tsconfig file in the project folder.

I pushed the change that I made in a new branch named typescript to my reposity

also, I repeat this process for a fresh CRA app, and the same error happened.

am I doing something wrong?

@await-ovo look at verifyNoTypeScript function in create-react-app/packages/react-scripts/scripts/utils/verifyTypeScriptSetup.js if there is typescript files, tsconfig.json must automatically create.

that’s right, it seems that this function is only used when init.
