  +This is used by default in `vue-loader@>=12` and can be disabled using the [optimizeSSR](https://vue-loader.vuejs.org/en/options.html#optimizessr) option.

  ### compiler.parseComponent(file, [options])
  Parse a SFC (single-file component, or `*.vue` file) into a descriptor (refer to the `SFCDescriptor` type in [flow declarations](https://github.com/vuejs/vue/blob/dev/flow/compiler.js)). This is used in SFC build tools like `vue-loader` and `vueify`.
