One is a new React Framework that makes Vite serve both native and web.

export function replaceLoader({
  code,
  loaderData,
}: {
  code: string
  loaderData: Object
}) {

  const out = (() => {
    if (!code.includes('__vxrn__loader__')) {
      return code + `\nexport const loader = () => (${stringifiedData})`
    }
    return code.replace(
      /["']__vxrn__loader__['"]/,
      // make sure this ' ' is added in front,
      // minifiers will do `return"something"
      // but if its null then it becomes returnnull
      ' ' + stringifiedData.replace(/\$/g, '$$$$')
    )
  })()

  return out
