'Cannot find module' error of meta.js when using local template

[crswll]

I can't seem to use meta.js instead of meta.json. I renamed the default webpack meta.json to meta.js and put a module.exports = at the start but it's telling me:

Error: Cannot find module 'vue-webpack-template/meta.js'

If I rename the file to meta.json and remove the module.exports = it works as expected. Am I doing something wrong?
