target,
    sourceMap,
    rootContext,
    resourcePath,
    resourceQuery
  } = loaderContext

  const rawQuery = resourceQuery.slice(1)
  const incomingQuery = qs.parse(rawQuery)
  const options = (loaderUtils.getOptions(loaderContext) ||
    {}) as VueLoaderOptions

  const isServer = target === 'node'
  const isProduction = mode === 'production'

  const { descriptor, errors } = parse(source, {
    filename: resourcePath,
    sourceMap
  })

  if (errors.length) {
    errors.forEach(err => {
      formatError(err, source, resourcePath)
      loaderContext.emitError(err)
    })
    return ``
  }

  // if the query has a type field, this is a language block request
  // e.g. foo.vue?type=template&id=xxxxx
  // and we will return early
  if (incomingQuery.type) {
