Build Module from `module.js` file

[ThornWalli]

Hello,

just trying to rewrite our module to "type": "module", because I wanted to resolve files in project .mjs to .js.

Unfortunately I got this error when running nuxt-module-build.

ℹ Building nuxt-speedkit

  plugin: 'commonjs--resolver',
  hook: 'resolveId',
  id: 'xxx/src/module.js',
  watchFiles: [ 'xxx/src/module.js' ]
}

Is it at all possible to use .js files instead of .mjs or .ts?

It is indeed. In Nuxt we do it like this:

https://github.com/nuxt/nuxt/blob/574a5616b43d0caeddd97ddea3abf7703efec295/packages/nuxt/build.config.ts#L10

You can create a build.config.ts in your project and the module builder should respect it.
