How I enable support for JS files that have JSX syntax insiede?

[rijans]

With vite-plugin-react-swc I get error of "Unexpected token" inside the start of jsx syntax. My component files are with .js extension, which is a very old project.

How do I enable this plugin to work with these files?

Using JSX inside JS will not be supported by this plugin.
Rename your js files containing jsx to .jsx or .tsx.
