I'm trying to move my project from js to ts, so I've installed typescript and now I'm changing the extension of all files from .js to .tsx, then I tried to launch again the project and seems that can't resolve .tsx files

This is the folder tree of my project (Note that I just changed my Button component to .tsx for testing purposes, not all files, otherwise I would get more errors)

This is the error I get in console

webpack 5.69.1 compiled with 1 error in 793 ms

ofc, If I just change the tsx extension to js it still works

Anyone have an idea?

Thank you!

The default CRA template is built for JavaScript and not TypeScript.

What you can do now is follow the steps in the article provided by Tiago. Also From next time if you want to use TypeScript by default then CRA does provide a template which is

npx create-react-app <App Name> --template typescript
