I'd like to not include .babelrc during build since SWC is disabled as a replacement for Babel. I only need .babelrc for a plugin for dev testing purposes that is not supported by SWC yet. I am told to check the doc about ignored compiler options but the page is down, and I could not find a solution from the nextjs document on disabling SWC and its feedback thread.
Super hacky, but you could modify the build script in package.json to temporarily rename the config file before the build then restore it after:
{
"scripts": {
"dev": "next dev",
"build": "mv .babelrc .babel_ && next build; mv .babel_ .babelrc",
"start": "next start",
"lint": "next lint"
}
}
It's not a cross-platform solution, however.
