Is it possible to do the same without using TypeScript?

I am trying to develop an extension for my project and I would like it to use React with javascript , following your example I always get the same problem and when using files with .jsx extensions the terminal shows me the following command: [RollupError] Unexpected token (Note that you need plugins to import files that are not JavaScript)

@FrancicoVerdu did you ever resolve this? I'm also facing the same error, and am stuck trying to solve it.

From what I can make out, the React .jsx file isn't being processed with the React plugins for Rollup, so it doesn't understand how to process the first < character of the JSX format.

@FrancicoVerdu¿Resolviste esto alguna vez? Yo también tengo el mismo error y no puedo resolverlo.

Por lo que puedo ver, el .jsxarchivo React no se procesa con los complementos de React para Rollup, por lo que no entiende cómo procesar el primer <carácter del formato JSX.

Unfortunately I never got to investigate it in depth as I decided to create a separate front end application with the options I wanted to add to the extension. Sorry I can't be of more help
