// Shim globals in cjs bundle
// There's a weird bug that esbuild will always inject importMetaUrl
// if we export it as `const importMetaUrl = ... __filename ...`
// But using a function will not cause this issue

const getImportMetaUrl = () =>
  typeof document === 'undefined'
    ? new URL(`file:${__filename}`).href
    : document.currentScript &&
        document.currentScript.tagName.toUpperCase() === 'SCRIPT'
      ? document.currentScript.src
      : new URL('main.js', document.baseURI).href

export const importMetaUrl = /* @__PURE__ */ getImportMetaUrl()
